Posted by John McHaleBLACKSBURG, Va., 2 June 2010. VPT, Inc., a HEICO company (NYSE:HEI.A) (NYSE:HEI), has introduced a new electromagnetic interference (EMI) filter module for distributed power systems in avionics systems. The new VPTc10-28 EMI filter satisfies strict reliability requirements for commercial avionics and military systems in the U.S. and Europe, VPT officials say."Often modules developed in the U.S. satisfy only U.S. requirements," says Michael J. Bosmann, senior vice president of marketing and sales. "However we've planned the development of this product and future products on a more global scale to meet the growing demands of avionics and military power systems designers whether they're in Europe or the United States. The additional benefit to our users is the ability to design their systems for universal power systems which they can sell into both European and USA markets without changes in power distribution design." The VPTc10-28 Series EMI filter and transient suppressor combines two modules in one space-saving package. This module reduces the reflected noise of DC-DC converters while simultaneously protecting a power system from inrush current damage and reverse polarity conditions. The new EMI filters feature:- as much as 10 amps of output current; - as many as 150 watts of output power; - wide input voltage range; - transient operation to as much as 80 volts per MIL-STD-704 and 100 volts per DEF STAN 61-5 Part 6 Issue 5 and MIL-STD-1275;- transient operation to as much as 202 volts per ISO 7637-2 and DEF STAN 61-5 part 6, issue 6; - 45 dB minimum attenuation at 500 kHz; - inrush current limiting; - reverse polarity protection; - temperature range from -55 to 100 degrees Celsius; - six-sided metal rugged enclosure; - meets conducted emissions requirements of DEF STAN 59-411 Part 3 Issue 1 and MIL-STD-461C/D/E/F when used with VPT series DC-DC converters;- meets conducted susceptibility requirements of DEF STAN 59-411 Part 3 Issue 1 for land applications, MIL-STD-461C, CS01, and CS02, and MIL-STD-461D/E/F when used with VPT series DC-DC converters; - intended for harsh environments including severe vibration, shock, and temperature cycling conditions; and - testing is to JESD22, MIL-STD-810, and MIL-STD-883.The new modules are priced beginning at $248.00 each in OEM quantities.
