Press Release Summary:
Suited for harsh electrical environments, 500 W Model DSF500 protects DC-DC converters from surges, spikes, and ripples found on electrical system of any military platform. Input voltage is 10-34 Vdc, while output voltage is tracked and clamped to below 36 Vdc. Measuring 2.28 x 2.28 x 65 in., unit also protects against over-current conditions. Should demand exceed 28 A, warning signal can be used to disable DSF500 or turn off attached devices to reduce current.
Original Press Release:
Active Filter Protects Dc-Dc Converters to MIL-STD 1275A-D Without any Additional Components
XP Power announces availability of its new 500W active filter unit for use in harsh electrical environments. The DSF500 is designed to protect dc-dc converters from the surges, spikes and ripples that are typically found on the electrical system of any military platform, such as an aircraft or vehicle. The filter meets the military specification, MIL-STD 1275A-D, without the need to incorporate any additional components. Platform mounted systems can utilize standard industrial dc-dc converters without the risk of failure or damage due to supply transients and noise. Input voltage is within the range 10 - 34 VDC. Output voltage is tracked and clamped to below 36 VDC.
The 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 2.28 x 2.28 x 0.65 inches (57.90 x 57.90 x 16.45 mm). 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.
The DSF500 is available now, priced $234 each in OEM quantities.
