Summary
The converters provide supplementary insulation with
SELV outputs as e.g. required in battery supported systems
where the bus voltage may exceed the SELV limit of
60 V DC. They are designed, built and approved according
to the international safety standards IEC/EN 60950, UL
1950, CAN/CSA C22.2 No.950-95.
The IMS 15 series of board mountable 15 Watt DC-DC con-
verters has been designed according to the latest industry
requirements and standards. The converters are particu-
larly suitable for applications in industry and telecommuni-
cations where variable input voltages or high transient
voltages are prevalent.
The circuit comprises of integrated planar magnetics and
all components are automatically assembled and solidly
soldered onto a single PCB without any wire connections.
The proprietary magnetic feedback solution ensures maxi-
mum reliability and repeatability in the control loop over all
operating conditions. Careful considerations of possible
thermal stresses ensure the absence of hot spots providing
long life in environments where temperature cycles are a
reality.The thermal design allows operation at full load up to
an ambient temperature of 71°C in free air without using
any potting material. An extended temperature range –
40...71°C is available as an option. For extremely high vi-
bration environments the case has holes for screw mount-
ing.
Providing two wide input voltage ranges, 14...36 V DC and
36...75 V DC, the units are available with single, dual and
electrically isolated double outputs allowing the configura-
tion of output voltages from 3.3 up to 48 V DC externally ad-
justable, with flexible load distribution on dual and double
output units. A shut down input allows remote converter on/
off. Features include efficient input and output filtering with
unsurpassed transient and surge protection, low output rip-
ple and noise, consistently high efficiency over the entire
input voltage range, high reliability as well as excellent dy-
namic response to load and line changes.

DC-DC Converters
IMS 15 Series
Functional Description
The IMS 15 series of DC-DC converters are magnetic feed-
back controlled flyback converters using current mode
PWM (Pulse Width Modulation).The -05- and -0503- output
voltage versions feature an active magnetic feedback loop
via a pulse transformer which results in very tight regulation
of the output voltage (see fig.: Block diagram, single and
-0503- output types).The output voltages of these versions
can be adjusted via the R input.The R input is referenced to
the secondary side and allows for programming of the out-
put voltages in the range of approximately 80 to 105% of
Uo nom using either an external resistor or an external volt-
age source.
Trim input. The Trim input is referenced to the primary side
of the converter and allows for programming of the output
voltages in the range 100 to 105% of Uo nom by an external
resistor or within 75 to 105% using an external voltage
source.The load regulation output characteristic allows for
paralleling of one or several double output units of equal
output voltages.
Current limitation is provided by the primary circuit, thus
limiting the total output power of double output types to
approx. 130% of Po nom (see: Type Survey). The shut down
input allows remote converter on/off.
Overtemperature protection will shut down the unit in ex-
cessive overload conditions with automatic restart approxi-
mately every 50 to 60 ms.
The voltage regulation on the dual and double output ver-
sions is achieved with a passive transformer feedback from
the main transformer (see fig.: Block diagram, for double
output types). The output voltages can be adjusted via the

Reverse Polarity Protection at the Input
The built-in suppressor diode also provides for reverse po-
larity protection at the input by conducting current in the re-
verse direction. An external fuse is required to limit this cur-
rent.
For very high energy transients as for example to achieve
IEC/EN 61000-4-5 or ETR 283 (19 Pfl1) compliance (as per
table :Electromagnetic Immunity) an external inductor and
capacitor are required.
– For 24 IMS 15 types a fast 3.15 A (F3.15A) fuse is
04009
recommended.
L
– For 48 IMS 15 types a fast 2 A (F2A) fuse is recom-
mended.

Connection in Parallel
Thermal Considerations
Double outputs of the same converter with equal output
voltage (e.g. 5V / 5V) can be put in parallel and will share
their output currents almost equally. Parallel operation of
single or double outputs of two or more converters with the
same output voltage may cause start-up problems at initial
start-up. This is only advisable in applications where one
converter is able to deliver the full load current as e.g. re-
quired in true redundant systems.
If a converter, mounted on a PCB, is located in free, quasi-
stationary air (convection cooling) at the indicated maxi-
mum ambient temperature TA max (see table: Temperature
specifications) and is operated at its nominal input voltage
and output power, the case temperature TC measured at the
Measuring point of case temperature TC (see: Mechanical
Data) will approach the indicated value TC max after the
warm-up phase. However, the relationship between TA and
TC depends heavily on the conditions of operation and inte-
gration into a system.The thermal conditions are influenced
by input voltage, output current, airflow, temperature of sur-
rounding components and surfaces and the properties of
the printed circuit board. TA max is therefore only an indica-
tive value and under practical operating conditions, the am-
bient temperature TA may be higher or lower than this value.
Short Circuit Behaviour
The current limit characteristic shuts down the converter
whenever a short circuit is applied to its output. It acts self-
protecting and automatically recovers after removal of the
overload condition (hiccup mode).
Output Overvoltage Protection
Caution: The case temperature TC measured at the
Measuring point of case temperature TC (see: Mechani-
cal Data) may under no circumstances exceed the speci-
fied maximum value. The installer must ensure that un-
der all operating conditions TC remains within the limits
stated in the table: Temperature specifications.
The output of single output units as well as -0503- and
-05-05- types are protected against overvoltages by a sec-
ond control loop. In the event of an overvoltage on one of
the outputs the unit will shut down and attempt to restart
approximately every 50 to 60 ms. Double and dual output
units (with exception of the -0503- and -05-05- types) are
protected against overvoltages by a Zener diode across the
second output. Under worst case conditions the Zener di-
ode will short circuit. Since with double output units both
outputs track each other the protection diode is only pro-
vided in one of the outputs. The main purpose of this fea-
ture is to protect against possible overvoltages which could
occur due to a failure in the feedback control circuit. The
output overvoltage protection is not designed to withstand
externally applied overvoltages.
Overtemperature Protection
The converters are protected from possible overheating by
means of an internal temperature monitoring circuit. It shuts
down the unit above the internal temperature limit and at-
tempts to automatically restart every 50 to 60 ms. This fea-
ture prevents from excessive internal temperature building
up which could occur in heavy overload conditions.

Shut Down Function
The outputs of the converters may be enabled or disabled
by means of a logic signal (TTL, CMOS, etc.) applied to the
shut down pin. If the shut down function is not required then
it should be left open-circuit.
Double output units (except -0503- types):
The Trim input is referenced to the primary side. The figure
below shows the circuit topology. Adjustment of the output
voltage is possible by means of either an external resistor

Programming of the output voltage by means of an exter-
nal resistor Rext is possible within a limited range of
100...105% of Uo nom. Rext should be connected between
the Trim pin and Vi–. Connection of Rext to Vi+ may dam-
age the converter. The following table indicates suitable
resistor values for typical output voltages under nominal
conditions (Ui nom, Io = 0.5 Io nom), with either paralleled
outputs or equal load conditions on each outputs.
Depending upon the value of the required output voltage,

Attempting to adjust the output below this range will

For external output voltage programming in the range

connected to the Trim pin and Vi–. The table below indi-
cates typical Uo versus Uext values under nominal condi-
tions (Ui nom, Io = 0.5 Io nom), with either paralleled outputs
or equal load conditions on each output. Applying a con-
trol voltage >20 V will set the converter into a hiccup
mode. Direct paralleling of the Trim pins of units con-
nected in parallel is feasible.

Safety and Installation Instructions
Installation Instruction
supply line. We recommend a fast acting fuse F3.15A for
24 IMS 15 types and F2A for 48 IMS 15 types.
Installation of the DC-DC converters must strictly follow the
national safety regulations in compliance with the enclo-
sure, mounting, creepage, clearance, casualty, markings
and segregation requirements of the end-use application.
Standards and approvals
All DC-DC converters are pending to be UL recognized
according to UL 1950, UL recognized for Canada to CAN/
CSA C22.2 No. 950-95 and LGA approved to IEC/EN
60950 standards.
Connection to the system shall be made via a printed circuit
board with hole diameters of 1.4 mm ±0.1 mm for the pins.
The units should be connected to a secondary circuit.
Check for hazardous voltages before altering any connec-
tions.
The units have been evaluated for:
• Building in
Do not open the module.
• Supplementary insulation input to output, based on their
maximum input voltage
• The use in a pollution degree 2 environment
• Connecting the input to a secondary circuit which is sub-
ject to a maximum transient rating of 1500 V
Ensure that a unit failure (e.g. by an internal short-circuit)
does not result in a hazardous conditions. See also: Safety
of operator accessible output circuit.
Input Fuse
After approvals the DC-DC converters are subject to manu-
facturing surveillance in accordance with the above men-
tioned UL, CSA, EN and ISO 9001 standards.
To prevent excessive current flowing through the input sup-
ply line in case of a short-circuit across the converter input
an external fuse should be installed in a non earthed input

Safety of Operator Accessible Output Circuit
The electric strength test is performed as factory test in ac-
cordance with IEC/EN 60950 and UL 1950 and should not
be repeated in the field. Power-One will not honour any
guarantee claims resulting from electric strength field tests.
If the output circuit of a DC-DC converter is operator acces-
sible, it shall be an SELV circuit according to IEC/EN 60950
related safety standards
The following table shows some possible installation con-
figurations, compliance with which causes the output circuit
of the DC-DC converter to be an SELV circuit according to
IEC/EN 60950 up to a configured output voltage of 42 V.

Option K
Option K configures the electrically isolated double outputs
to the alternative pinout with outputs connected in series
(Vo+/Go/Vo–) and common ground.
However instead of using units with option K, it is recom-
mended to use the standard double output units by provid-
ing the printed circuit board with an additional pin hole (for
pin 12 of double output units) connected to pin hole 13.This
will provide more design-in flexibility since by that both
pinouts may be used on the same PCB.
See also fig. Block diagram, double output units, standard
pinout.
Option i Inhibit
Excludes shut down and option K, or C.
The output(s) of the converter may be enabled or disabled
by means of a logic signal (TTL, CMOS, etc.) applied to the
inhibit pin. No output voltage overshoot will occur when the
unit is turned on. If the inhibit function is not required the
inhibit pin should be connected to Vi– to enable the output
(active low logic, fail safe).
