DSF500’s low loss, MOSFET-based protection circuit ensures that the unit can provide continuous reverse voltage protection. Attached systems are protected from incorrect, potentially damaging, electrical supply connections. The filter also protects against over current conditions. Should the demand exceed 28 Amps, a warning signal is given that can be used either to disable the DSF500 or turn off the attached devices in order to reduce the current. A disable function allows the system designer to turn off the unit remotely if required.
The unit measures 57.90 x 57.90 x 16.45 mm (2.28 x 2.28 x 0.65 inches). It is believed that no other competitor produces an active filter in such a small package that meets MIL-STD 1275A-D and can deliver 28 Amps. Compliance to electro-magnetic immunity MIL-STD 461E specification can also be achieved by following steps detailed in an applications note available from XP Power.
