Description
The DC-DC converters have been developed as a re-
sponse to the increasing need for decentralised power sup-
ply systems. They are especially suitable for powering
small loads on PCBs and for realising redundant systems.
Five input to output isolation test voltage categories and
three temperature ranges are available. The DC-DC con-
verters feature low output ripple, low module height, high
quality and reliability. To minimize feedback effects in the
supply system, the modules are equipped with an efficient
low-pass Pi input filter.
All modules are manufactured according to ISO 9001.
Case: DIL 24 package, grey colored plastic material, self
cooling (free air convection).

2 See Block Diagrams
3 The output current of one output may be increased by 25% if the output current of the other output is reduced by 25% simultaneously.
Example for a 5 IWR 1-1515-N: The +15 V output current of 33 mA may be increased to 41 mA if the –15 V output current is reduced
to 25 mA.
4 The output current of both outputs of the 12, 24, 28 and 48 V input types may be increased by 20% of Io nom. Note 3 is applicable at
the same time. Example for a 24 IWR 1-2×1212-N: Io1 = +29 mA/–19 mA, Io2 = +19 mA/–29 mA or Io1 = ±19 mA, Io2 = ±29 mA

Safety Instructions
If the output circuit of a DC-DC converter is operator-acces-
sible according to the IEC 950 related safety standards, it
shall be an SELV circuit (Safety Extra Low Voltage circuit,
i.e. a circuit, separated from mains by at least basic insula-
tion, that is so designed and protected that under normal
and single fault conditions, the voltage between any two
conductors and between any conductor and earth does not
exceed DC 60 V).
In the following section an interpretation is provided of the
IEC 950 safety standard with respect to the safety status of
the output circuit. However, it is the sole responsibility of the
installer or user to assure the compliance with the relevant
and applicable safety standards.
If the following table is observed, the output of any DC-DC
converter is considered to be an SELV circuit up to a nomi-
nal output voltage of 30 V (2 x 15 V in series).

Isolation Tests
Input to output isolation voltage tests are performed as factory tests (100%) and should not be repeated in the field.

For production test purposes in accordance with IEC 950/EN 60950
Factory test procedure
Groups 03, 05, 08 and 13
In combination with the high isolation strength of the potting compound, isolation test voltages mentioned are guaranteed.
Connection in Series
If the outputs of one or more units are connected in series
each individual output should be protected by a zener diode
or preferably by a suppressor diode to avoid overvoltages
or reverse polarity at the individual outputs, e.g.:
– 1N5908 to protect 5 V outputs
+Vo
+Uo
Unit 1
Go
– BZW04-11 to protect 12 V outputs
– BZW04-14 to protect 15 V outputs
–Vo
(or equivalent types)
Such destructive voltages may occur at switch-on cycle of
the converters, if the output voltages do not rise at the same
time. The "slower" output(s) could be supplied and, as a
result, destroyed by the "faster" output(s) via the load. The
maximum output current is limited by the lowest current
limitation.
+Vo
Unit 2
Go
Connection in Parallel
–Vo
–Uo
Connection of the outputs of one or more units in parallel is
not permitted. The load distribution and the ripple values
could not be controlled.
Fig. 1
Outputs connected in series
Cleaning
Two CFC free cleaning solvents have been tested and can
be recommended:
Submersion of the units in water for rinsing is permitted.
Drying should be done in the air.
