Thursday, May 26, 2016 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. The 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.
