Description
panel allow for a check of the main output voltage.
Full system flexibility and n+1 redundant operating mode are
possible due to virtually unrestricted series or parallel
connection capabilities of all outputs. In parallel connection of
several converters, automatic current sharing is provided by a
single-wire interconnection.
These extremely compact DC-DC converters incorporate all
necessary input and output filters, signaling and protection
features, which are required in the majority of applications.
The converters provide important advantages such as flexible
output power through primary current limitation, high
efficiency, excellent reliability, very low ripple and RFI noise
levels, full input to output isolation, negligible inrush current,
overtemperature protection, and input over-/undervoltage
lockout. The converter inputs are protected against surges
and transients occurring on the source lines.
As a modular power supply or as part of a distributed power
supply system, the extremely low profile design significantly
reduces the necessary power supply volume without
sacrificing high reliability. A temperature sensor disables the
outputs, if the case temperature exceeds the limit. The outputs
are automatically re-enabled, when the temperature drops
below the limit.
The converters are particularly suitable for rugged
environments, such as railway applications. They have been
designed in accordance with the European railway standards
EN 50155 and EN 50121-3-2. All printed circuit boards are
coated with a protective lacquer.
The fully enclosed, black-coated aluminum case acts as a heat
sink and an RFI shield. The converters are designed for 19"
DIN-rack systems occupying 3 U/4 TE only, but can also be
chassis-mounted by means of four screws. Fitting an
additional heat or ordering options with fitted heat sink is
possible as well.
The outputs are continuously open- and short-circuit proof. An
isolated output Power Good signal and LEDs at the front panel
indicate the status of the converter. Test sockets at the front

The current limitation is located at the primary side, thus
limiting the total output current in overload conditions. This
allows flexible loading of each output for unsymmetrical loads
in the range 10 to 90% of the total output power. In applications
with large dynamic load changes, we recommend connecting
such a load to output 1. If output 2 is not used, it should be
connected parallel to output 1. Both outputs can either be
series- or parallel-connected (see Electrical Output Data).
Functional Description
The converters are designed as forward converters using
primary and secondary control circuits in SMD technology. The
switching frequency is approximately 200 kHz under nominal
operating conditions. The built-in high-efficient input filter
together with a small input capacitance generate very low
inrush currents of short duration. After transformer isolation
and rectification, the output filter reduces ripple and noise to a
minimum without compromising the dynamic ability. The
output voltage is fed to the secondary control circuit via
separate sense lines. The resultant error signal is sent to the
primary control circuit via a signal transformer.
In normal operation, the internal control circuits are powered
by a third winding of the main choke (except 48Q models).
Start-up is ensured from the input voltage by a linear regulator.
Note: When the output voltage is much lower then the nominal
value, this linear regulator is activated, generating considerable
power losses.
Double-output models have the voltage regulation of output 2
relying on the close magnetic coupling of the transformer and
the output inductor together with the circuits' symmetry.

Input Fuse
Input Stability with Long Supply Lines
An incorporated fuse in series to the negative input line
protects against severe defects. The fuse is not externally
accessible. Reverse polarity at the input will cause the fuse to
blow.
If a Q Series converter is connected to the power source with
long input lines which exhibit a considerable inductance, an
additional external capacitor connected in parallel to the input
improves stability and avoids oscillations.
Note: Customer-specific models with no internal fuse are
available on request; the customer must prevew an external fuse
according to table 3.
Actually, a Q Series converter with nominal load acts like a
negative resistor, as the input current rises when the input
voltage decreases. It tends to oscillate with a resonant
frequency determined by the line inductance Lext and the input
Table 3: Fuse specifications
capacitance Ci + Cext and damped by the resistors Ri + Rext
.
The whole system is not linear at all and eludes a simple
calculation. One basic condition is given by the formula:

Rext is the series resistor of the source voltage including input

stable operating conditions. Worst case conditions are low

Low inductance Lext of the input lines and a parallel connected
input capacitor Cext are helpful. Recommended values for Cext
are given in table 4, which should allow stable operation up to
an input inductance of 2 mH.
Input Transient Protection
A metal oxide VDR (Voltage Dependent Resistor) together with
the input fuse and a symmetrical input filter form an effective
protection against high input transient voltages, which typically
occur in most installations, especially in battery-driven mobile
applications.

Nominal battery voltages in use are: 24, 36, 48, 60, 72, 96, and

In some applications, surges according to RIA 12 are specified
in addition to those defined in IEC 60571-1 or EN 50155. The
power supply must not switch off during these surges and
since their energy can practically not be absorbed, an
extremely wide input voltage range is required. The Q Series
input range has been designed and tested to meet most of
these requirements. See also Electromagnetic Immunity.

The inherent inrush current value is lower than specified in the
standard ETS 300132-2. The converters operate with
relatively small input capacitance, resulting in low inrush
current of short duration. As a result, in a power-bus system
the converters can be hot-swapped, causing negligible
disturbance.

output voltage regulation, the sense lines are connected after
the ORing diodes. The T pins should be connected together to

Fig. 10b shows a quite similar circuit with ORing diodes DR, but
with different output loads. To compensate for the voltage drop
of the ORing diodes (if necessary), an auxiliary circuit is added
to each power supply consisting of a small diode DS and a
small resistor RS. We recommend a current of approximately 10
mA through DS and RS. Only Load 0 benefits from a secured

Caution: Do not connect the sense lines after the ORing diodes,

the converters switches off and the ORing diode is blocking, a
reverse voltage can appear between the sense pin and the

In a symmetrical configuration the output 1 with open R input is

Vo2 depends upon the load distribution: If each output is loaded

Double-output models with 12 V: Voltage deviation of Vo2
versus Io2 for different currents on output 1
In double-output models, only the total current is limited,
allowing free choice of load distribution between the two
outputs, up to Io1 + Io2 ≤ Io max. However, a small current should
remain on both outputs to guarantee good voltage regulation.
In case of overload (Io1 + Io2 > Io max) both output voltages are
reduced simultaneously.

Current distribution in overload is dependent upon the type of
overload. A short-circuit in one output will cause the full current
flow into that output, whereas a resistive overload results in
more even distribution and in a reduced output voltage.

If a converter is located upright in quasi-stationary air

is operated at its nominal input voltage and output power, the
temperature TC measured at the Measuring point of case
temperature (see Mechanical Data) will approach TC max after

Note: T-function only increases the output voltage, until the
currents are evenly shared. If in a redundant system, one
converter fails, the remaining converters keep sharing their
currents evenly.
Current Sharing
The current sharing facility should be used when several
converters are operated in parallel or redundant connection.
This feature avoids that some converters are driven into
current limitation and thus produce excessive losses. As a
result, the stress of the converters is reduced, and the system
reliability is further improved.
Since the T pins are referenced to the pins S–, the S– pins of
all converters must have the same electrical potential.
Double-output converters with both outputs connected in
series can also be paralleled with current sharing, if pins Vo1–
of all converters are connected together, see fig. 8c.
Simple interconnection of the T pins causes the converters to
share the output current. The current tolerance of each
converter is approx. ±20% of the sum of its nominal output
If the output voltages are programmed to a voltage other than
Vo nom by means of the R pin or option P, the outputs should be
adjusted individually within a tolerance of ±1%.
currents Io1 nom + Io2 nom
.
In n+1 redundant systems, a failure of a single converter will
not lead to a system failure, if the outputs are decoupled by
diodes; see fig. 10.
Important: For applications using the hot-swap capabilities,
dynamic output voltage changes during plug-in/plug-out must be
considered.

Q Series Data Sheet
66 – 132 Watt DC-DC Converters
®
Applying generously dimensioned cross-section load leads
help avoiding troublesome voltage drops. To minimize noise
pick-up, wire the sense lines parallel or twisted. For
unsymmetrical loads, we recommend connecting the sense
lines directly at the female connector.
Output Good Signal (Out-OK)
The isolated Out-OK output gives a status indication of the
converter and the output voltage. It can be used for control
functions such as data protection, central system monitoring or
as a part of a self-testing system. It can be connected to get a
centralized fault detection or may be used for other system-
specific applications at the primary or the secondary side of
the converter.
To ensure correct operation, both sense lines must be
connected to their respective power output. With double-
output models, the sense lines must be connected to output 1
only. Caution should be exercised, if outputs are series-
connected, as the compensated voltage is effectively doubled.
Because the effective output voltage and output power are
increased by the sense lines, the minimum input voltage rises
proportionally to the compensated output voltage.
Connecting the Out-OK as per fig. 22, VOK <1.0 V indicates that
the Vo or Vo1 of the converter is within the range Vt1 low – Vt1 high
Vt1 low corresponds to 0.95 - 0.98 Vo1 nom, Vt1 high to 1.02 – 1.05
Vo1 nom
.
.
Note: Using the R-input or the option P, the monitor level is
tracking the programmed output voltage.
Caution: Sense lines should always be connected. Incorrectly
connected sense lines may cause an overvoltage at the ouput,
which could damage the output load and activate the second
control loop. The sense lines can handle only small currents.
In an error condition, if the output voltage is out of range due to
overload or an external overvoltage, VOK will approach Vp.
The output is formed by an NPN transistor. The emitter (Out
OK–) can be connected to primary Vi– or secondary Vo1– to
get an open-collector output. In a configuration of several Q
Series converters, the Out OK pins can be series-connected in
order to get a system level signal (as shown in fig. 9). If one of
the converters fails, the series-connected output rises to high
impedance.

The Vi– input (pin 32) is internally fused. This fuse is designed
to protect in case of overcurrent and may not be able to satisfy
all customer requirements. External fuses in the wiring to one
or both input pins (no. 30 and/or no. 32) may therefore be
necessary to ensure compliance with local requirements.
Safety and Installation Instructions
Connector Pin Allocation
The connector pin allocation table defines the electrical
potentials and the physical pin positions on the H15 connector.
Pin no. 26, the protective earth pin, is a leading pin, ensuring
that it makes contact with the female connector first.
Important:
• If the inhibit function is not used, pin 28 (i) must be connected
with pin 32 (Vi–) to enable the output(s).

Due to high output currents, the Q1001/1101 models offer two
internally parallel-connected contacts for both, the positive and
the negative output path (pins 4/6 and pins 8/10). It is
recommended to connect the load to both female connector
pins of each path in order to keep the voltage drop across the
connector pins to a minimum.

Installation Instructions
The
Q
Series converters are components, intended
The converters have been evaluated for:
• Class I equipment
exclusively for inclusion within other equipment by an
industrial assembly operation or by professional installers.
Installation must strictly follow the national safety regulations
in compliance to enclosure, mounting, creepage, clearance,
casualty, markings and segregation requirements of the end-
use application.
• Building in
• Basic insulation between input and case and double or
reinforced insulation between input and output, based on
their maximum rated input voltage
Connection to the system shall be made via the female
connector H15 (see Accessories). Other installation methods
may not meet the safety requirements.
• Basic insulation between Out-OK and case, and double or
reinforced insulation between Out-OK and input, and
between Out-OK and output, based on their maximum rated
input voltage
The Q Series converters are provided with pin 26 ( ), which is
reliably connected to the case. For safety reasons it is
essential to connect this pin to protective earth; see Safety of
Operator-Accessible Output Circuits.
• Functional insulation between outputs and output to case
• Use in a pollution degree 2 environment

Safety of Operator-Accessible Output Circuits
If the output circuit of a DC-DC converter is operator-
accessible, it shall be an SELV circuit according to IEC 60950.
Railway Applications
The Q Series converters have been designed by observing the
railway standards EN 50155, EN 50121-3-2, and EN 50121-4.
All boards are coated with a protective lacquer.
Table 21 shows some possible installation configurations,
compliance with which causes the output circuit of the DC-DC
converter to be SELV up to a configured output voltage (sum of
nominal voltages, if in series configuration) of 35 V.
The converters comply with class S1 of the fire protection
standard E DIN 5510-2 (Oct. 2007).
However, it is the sole responsibility of the installer to ensure
the compliance with the relevant and applicable safety
regulations.
Isolation and Protective Earth
The test of the resistance of the protective earthing circuit
reduced accordingly, so that the maximum specified output
power is not exceeded.
Description of Options
Option P: Output Voltage Adjustment
Option -7: Temperature Range
Option P provides a built-in multi-turn potentiometer, which
allows an output voltage adjustment of ±10% of Vo nom. The
potentiometer is accessible through a hole in the front cover.
Option -7 designates converters with an operational ambient
temperature range of –25 to 71 °C. Not for new designs.
With double-output models, both outputs are affected by the
potentiometer. If converters are parallel-connected, their in-
dividual output voltage should be set within a tolerance of ±1%.
Option B, B1: Additional Heat Sink
Thickness: 12.5 mm (opt. B) or 20 mm (opt. B1)
If Vo is set higher than Vo nom, the output currents should be

The maximum rated input voltage of EQ models acc. to IEC/EN 60950 is 150 V. Power-One specifies the tolerance as +12% (max. 168 V)
The earth connection has to be provided by the installer according to IEC/EN 60950.
Based on the maximum rated output voltage provided by the front end.
The installer shall provide an approved fuse with the lowest rating suitable for the application in a non-earthed input conductor directly at
the input of the DC-DC converter (see fig. Schematic safety concept). For UL’s purposes, the fuse needs to be UL-listed.
Each suppressor diode should be dimensioned such that in the case of an insulation fault the diode is able to limit the output voltage to
SELV (<60 V), until the input fuse blows (see fig. Schematic safety concept).
Has to be insulated from earth according to IEC/EN 60950, by at least supplementary insulation, based on the maximum nominal output
voltage from the front end.
