Description
safety agencies TÜV and UL (USA and Canada).
The H series of DC-DC converters represents a broad and
flexible range of cassette power supplies for use in
advanced electronic systems. Features include high
efficiency, reliability, and reasonable output voltage noise.
The case design allows operation at nominal load up to
50 °C in a free air ambient temperature. If forced cooling is
provided, the ambient temperature may exceed 50 °C, but
the case temperature should remain below 80 °C under all
conditions.
The converter inputs are protected against surges and
transients occuring at the source lines. Input over- and
undervoltage cut-out circuitry disables the outputs if the
input voltage is outside the specified range.
A temperature sensor generates an inhibit signal which
disables the outputs if the case temperature TC exceeds the
limit. The outputs are automatically re-enabled when the
temperature drops below the limit.
All outputs are open- and short-circuit proof and are
protected against overvoltages by means of built-in
suppressor diodes. The outputs can be inhibited by a logic
signal applied to the connector pin 2 (i). If the inhibit
function is not used, pin 2 should be connected to pin 23 to
enable the outputs.
Various options are available to adapt the converters to
individual applications.
The converters may either be plugged into 19-inch rack
systems according to DIN 41494, or be chassis mounted.
LED indicators display the status of the converter and allow
visual monitoring of the system at any time.
Full input-to-output, input-to-case, output-to-case, and
output-to-output isolation is provided. The converters are
designed and built according to the international safety
standard IEC/EN 60950 and have been approved by the

Functional Description
transistor.This signal is fed back via a coupling transformer.
The input voltage is fed via an input filter to the input
capacitor.This capacitor sources a single-transistor forward
converter. Each output is powered by a separate secondary
winding of the main transformer. The resultant voltages are
rectified and their ripples smoothed by a power choke. The
control logic senses the main output voltage Vo1 and
generates, with respect to the maximum admissible output
currents, the control signal for the primary switching
The auxiliary outputs Vo2 and Vo3 are unregulated. Each
auxiliary output's current is sensed and transferred to the
main control circuit using a current transformer. If one of the
outputs is driven into current limit, the other outputs will
reduce their output voltages as well because all output
currents are controlled by the same control circuit.

Input Fuse
The converters do not incorporate any fuse. External fuses
installed in the wiring to the inputs are essential.
If the input voltage remains below 0.8 Vi min or exceeds
1.1 Vi max (approx. values), an internally generated inhibit
signal disables the output(s). When checking this function
the absolute maximum input voltage rating Vi abs must be
carefully considered (see table: Electrical Input Data).
Between Vi min and the undervoltage lockout level the output
voltage may be below the value defined in table: Output
data (see: Technical Information: Measuring and Testing).

Output Protection
Each output is protected against overvoltages which could
occur due to a failure of the internal control circuit. Voltage
suppressor diodes (which under worst case condition may
become a short circuit) provide the required protection.The
suppressor diodes are not designed to withstand externally
applied overvoltages. Overload at any of the outputs will
cause a shut-down of all outputs.

Main outputs of equal nominal voltage can be connected in
parallel. It is important to assure that the main output of a
multiple-output converter is forced to supply a minimum
current of 0.1 A to enable correct operation of its own
auxiliary outputs.
Fig. 4
H2540/H3040: ΔVo2/3 (typ.) versus Io2/3 with different Io1
Outputs one and two of a double-output model may be
connected in parallel without
a
minimum current
requirement at the main output. Outputs two and three of a
triple-output model can be connected in parallel.
In parallel operation, one or more of the main outputs may
operate continuously in current limitation which will cause
an increase in case temperature. Consequently,
a
reduction of the maximum ambient temperature by 10 K is
recommended.
Main or auxiliary outputs can be connected in series with
any other output of the same or another converter. In series
connection, the maximum output current is limited by the
lowest current limit. Output ripple and regulation values are
added. Connection wiring should be kept as short as
possible.
If output terminals are connected together in order to
establish multi-voltage configurations, e.g. +5.1 V, 12 V
etc. the common ground connecting point should be as
close as possible to the connector of the converter to avoid
excessive output ripple voltages.

However, the relationship between TA and TC depends
heavily on the conditions of operation and integration into a
system. The thermal conditions are influenced by input
voltage, output current, airflow and temperature of
surrounding components and surfaces. TA max is therefore,
contrary to TC max, an indicative value only.

Caution: The installer must ensure that under all

Notes: Sufficient forced cooling or an additional heat sink
allows TA to be higher than 50 °C (e.g. 65 °C) if TC max is not
exceeded.
Thermal Protection
A temperature sensor generates an internal inhibit signal
which disables the outputs if the case temperature exceeds

Installation Instructions
In order to avoid possible damage, any penetration of
liquids (e.g. cleaning fluids) is to be prevented, since the
power supplies are not hermetically sealed.
The H series DC-DC converters are components, intended
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 with the enclosure, mounting,
creepage, clearance, casualty, markings, and segregation
requirements of the end-use application. See also:
Technical Information: Installation and Application.
Standards and Approvals
12H to 48H DC-DC converters correspond to class I
equipment. All types are UL recognized according to UL
1950, UL recognized for Canada to CAN/CSA C22.2 No.
950-95 and TÜV approved to IEC/EN 60950 standards.
Connection to the system shall be made via the female
connector H11 (see: Accessories). Other installation
methods may not meet the safety requirements.
The units have been evaluated for:
•
•
Building in
Supplementary insulation between input and case and
double or reinforced insulation between input and
output, based on 250 VAC and 400 VDC
Operational insulation between output(s) and case
Operational insulation between the outputs
The use in a pollution degree 2 environment
Connecting the input to a primary or secondary circuit
with a maximum transient rating of 2500 V.
All DC-DC converters are provided with pin no. 26 ( ),
which is reliably connected with their case. For safety
reasons it is essential to connect this pin with the protective
earth of the supply system if required in: Safety of operator
accessible output circuit.
•
•
•
•
Ensure that a cassette failure (e.g. by an internal short-
circuit) does not result in a hazardous condition. See also:
Safety of operator accessible output circuit.
The DC-DC converters are subject to manufacturing
surveillance in accordance with the above mentioned UL,
CSA, EN and with ISO 9001 standards.
To prevent excessive current flowing into the cassette (e.g.
by an internal short-circuit), an external fuse suitable for the
application and in compliance with the local requirements
should be installed in the wiring to one or both input pins
(no. 29 and/or no. 32). See also: Input Fuse.
Protection Degree
Condition: Female connector fitted to the unit.
Important: Whenever the inhibit function is not in use,
pin no. 2 (i) should be connected to pin no. 23 (Vo1–) to
enable the output(s).

Do not open the modules, or guarantee will be
invalidated.
Isolation
Make sure that there is sufficient airflow possible for
convection cooling. This should be verified by measuring
the case temperature when the unit is installed and
operated in the end-use application. The maximum
specified case temperature TC max shall not be exceeded.
See also: Thermal Considerations.
The electric strength test is performed as a factory test in
accordance with IEC/EN 60950 and UL 1950 and should
not be repeated in the field. Power-One will not honor any
guarantee/warranty claims resulting from electric strength
field tests.
If the end-product is to be UL certified, the temperature of
the main isolation transformer should be evaluated as part
of the end-product investigation.

50 Watt DC-DC Cassette Converters
Safety of operator accessible output circuit
If the output circuit of a DC-DC converter is operator
accessible, it shall be a SELV circuit according to the IEC/
EN 60950 related safety standards.
Only voltage adaptation and rectification to the specified
input voltage range of the DC-DC converter is needed.
The following table shows some possible installation
configurations, compliance with which causes the output
circuit of the DC-DC converter to be a SELV circuit
according to IEC/EN 60950 up to a configured output
voltage (sum of nominal voltages if in series or +/–
configuration) of 36 V.
Since the H series DC-DC converters provide double or
reinforced insulation between input and output, based on a
rated primary input voltage of 250 VAC and 400 VDC only
operational insulation is needed between the AC mains and
the input of the DC-DC converter. This means that there is
no need for an electrical isolation between the AC mains
circuit and the DC-DC converter input circuit to cause the
output of an H series DC-DC converter to be a SELV circuit.
However, it is the sole responsibility of the installer to
assure the compliance with the relevant and applicable
safety regulations. More information is given in: Technical
Information: Safety.

3 The earth connection has to be provided by the installer according to the relevant safety standard, e.g. IEC/EN 60950. If the converter
case shall not be connected with earth, the front end output circuit has to be insulated from earth according to the relevant safety
standard by at least basic insulation, based on the maximum nominal output voltage from the front end, and insulated from the

D Undervoltage Monitor
The input and/or output undervoltage monitoring circuit
operates independently of the built-in input undervoltage
lockout circuit. A logic "low" (JFET output) or "high" signal
(NPN output) is generated at pin 5 as soon as one of the
monitored voltages drops below the preselected threshold
level Vt. The return for this signal is Vo1– (pin 23). The D
output recovers when the monitored voltage(s) exceed(s)
Vt+Vh. The threshold level Vt is adjustable by
a
potentiometer, accessible through a hole in the front cover.
Option D exists in various versions D1 to D8 as shown in
the following table.

across the input filter. The value of ΔVti depends upon the
input voltage range, threshold level Vt, temperature, and
input current. The input current is a function of the input
voltage and the output power.

This option defines an undervoltage monitoring circuit
for the input or the input and main output voltage equivalent
to option D, and generates the ACFAIL signal (V signal)
which conforms to the VME standard. The low state level of
the ACFAIL signal is specified at a sink current of IV = 48
mA to VV -0.6 V (open-collector output of a NPN transistor).
The pull-up resistor feeding the open-collector output
should be placed on the VME backplane.

where as:
Ci min = minimum internal capacitance [mF], according to
the table below
Ci ext = external input capacitance [mF]
After the ACFAIL signal has gone low, the VME standard
requires a hold-up time th of at least 4 ms before the 5.1 V
output drops to 4.875 V when the 5.1 V output is fully
loaded. This hold-up time th should be provided by an
external input capacitance. Consequently the working input
voltage and the threshold level Vt i should be adequately
above the minimum input voltage Vi min of the converter so
that enough energy is remaining in this capacitance.

Vti = threshold level [V]
If the input voltage is below the required level, an external
hold-up capacitor (Ci ext) should be added.
Remarks: The threshold level Vti of option V2 and V3 is
adjusted during manufacture to a value according to table
Undervoltage monitor functions, section Option D.
Table 18: Available internal input capacitance and factory
potentiometer setting of Vti with resulting hold-up time.
A decoupling diode should be connected in series with the
input to avoid the input capacitance discharging through
other loads connected to the same source voltage.

level Vt is adjustable by a potentiometer accessible through
a hole in the front cover.
Option V operates independently of the built-in input
undervoltage lockout circuit. A logic "low" signal is
generated at pin 5 as soon as one of the monitored voltages
drops below the preselected threshold level Vt. The return
for this signal is Vo1– (pin 23). The V output recovers when
Versions V2 and V3 are available as shown below.

If Vi is monitored, the internal input voltage is measured
after the input filter. Consequently this voltage differs from
the voltage at the connector pins by the voltage drop ΔVti
across input filter and rectifier. The value of ΔVti depends
upon the input voltage range, threshold level Vt,
temperature, and input current. The input current is a
function of input voltage and output power.
