XP Power has introduced a filtering and active surge suppression module that enables fast design of military specification (MIL STD) power systems using industrial DC/DC converters.

According to the press release, the new DSF200LV module reduces design time and cost, and system time-to-market. It is a 200W unit for use in 24/28V power systems in military vehicles, aircraft and naval vessels. It enables system compliance with MIL-STD 461E CE102 and DEF STAN 59-41 DCE01/DCE02 for electromagnetic compatibility, and MIL-STD 1275A/B and DEF STAN 61-5 Part 6 for surge and transient suppression.

The module has an input voltage range of 9Vdc to 36Vdc, and is clamped at a maximum output voltage of 36Vdc. It is rated at 7A continuous output with a baseplate temperature between -40C and 100C.

The filter is 92 to 98 percent efficient, enabling the device to generate minimal heat. Under no-load conditions it consumes 50?A. Additionally, the device has low-loss reverse voltage protection and has a series resistance of 0.26 ohm.

Measuring 61.2-by-36.8-by-13mm, the DSF200LV is designed for PCB mounting and is housed in a conductively-plated steel case with an aluminum baseplate for cooling.

The DSF200LV module is priced at $151 each for 1,000-piece orders.
