Active surge protection filter module complies with DEF STAN 61-5 issue 6 load dump requirement

Active surge protection
The DSF226 EMC filter and surge protection module is designed for use in 28 VDC input defense applications. The PCB mounting module is encapsulated within a six sided metal enclosure and is able to support up to 200 Watts output power to drive downstream DC-DC converters.

The DSF226 complies with DEF STAN 61-5 part 6 issue 6 load dump requirements and meets the internationally recognised immunity and emission standards MIL-STD 1275A-D, DEF STAN 59-411 & MIL-STD 461C. Providing active surge protection, the unit allows for the full output power to be supplied over the entire 15 - 33 VDC, accommodating transients down to 10 VDC for up to 1 s. The output of the module tracks the input voltage and is clamped at < 36 VDC.

The DSF226 operates from -46°C to + 100°C and a thermal warning output is available to control the end-application or disable the filter output.

DSF226_Mechanical_Drawing.jpgThe DSF226 filter and surge protection module is ideal for use in combination with XP Power's MTC family of military-specification DC/DC converters, QSB and ICH series of power bricks. The DSF226 can also be combined with XP Power's J series of 24V 4:1 input converters for multiple output COTS defence applications.
