BLACKSBURG, Va., 24 Feb. 2015.VPT Inc., a HEICO company (NYSE:HEI) with headquarters in Blacksburg, Va., is introducing the latest addition to the company’s high-reliability commercial off-the-shelf (COTS) product line -- VPT250-2800S Series single output 250-watt isolated DC-DC converters – to meet growing power conversion needs in military vehicles, weapons, and rugged systems requiring high reliability.
The new VPT250 Series is specifically intended for programs with harsh environments such as severe shock, vibration and thermal stresses. The product line features VPT’s proprietary six-sided encapsulated package with an integral metalized electromagnetic interference (EMI) shield, and are compatible with aqueous cleaning processes.
“The VPT250 provides design engineers with 25 percent more power in the same package envelope while improving electrical performance in key areas,” explains Monty Pyle, vice president, sales and marketing for VPT Inc. in Bothell, Wash. Our new epoxy encapsulated packaging provides the VPT250 with an integral EMI shield, protection from cleaning or application solvents and chemicals, as well as the option of thermal conduction from either the top or bottom surface.
The VPT250 boasts a wide input-voltage range (16 to 40 volts per MIL-STD-704 and MIL-STD-1275) and delivers 250 watts at efficiencies up to 92 percent from -55ºC to 100ºC. The VPT250 Series takes advantage of synchronous rectification topology and thermally conductive epoxy encapsulated packaging to deliver high-efficiency, fixed-frequency operation, low input and output ripple, and superior thermal dissipation, according to a company spokesperson. The VPT250 also provides parallel current-sharing capability up to 1,250 watts.
“Our customers said they need more power in the same space, impervious packaging and greater mounting flexibility without compromising electrical performance. The VPT250 checks all those boxes and more,” concludes Pyle.
VPT Inc., part of the HEICO Electronic Technologies Group, leads the industry in providing innovative DC-DC power converters, EMI filters, and custom engineering services for avionics, military, and space applications.
