Input Transient Voltage Protection
A built-in suppressor diode provides effective protection
against input transients which may be caused for example
by short-circuits accross the input lines where the network
inductance may cause high energy pulses.

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.

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 24 IMS 15 types a fast 3.15 A (F3.15A) fuse is
recommended.
– For 48 IMS 15 types a fast 2 A (F2A) fuse is recom-
mended.

1 Flexible load distribution: 24/48 IMS 15-0503 types; 2 A max. on one of the 2 outputs, the other output should not be loaded such that
the total output power exceeds
Po nom according to table: Type survey.
2 The current limit is primary side controlled.
3 Measured with both outputs connected in parallel. For -0503- types: total capacitance, both outputs.
4 Conditions for specified output. Other output loaded with constant current Io = 0.5 Io nom.
5 BW = 20 MHz
6 Measured with a probe according to EN 61204
7 The overvoltage protection is not tracking with R/Trim control.
