BLACKSBURG, Va., 5 May 2015. VPT Inc., a HEICO company (NYSE:HEI), is launching its new VXR Series of DC-DC converters and electromagnetic interference (EMI) filters at the annual Association for Unmanned Vehicle Systems International (AUVSI) conference in Atlanta, Georgia.

The VXR Series, the latest addition to the company’s high-reliability product family, includes models ranging from 7 watts to 100 watts with a wide continuous input voltage range from 9 volts DC (VDC) to 60 VDC and transient operation from 6 VDC to 80 VDC. The new product line is optimized for a broad range of applications, including commercial and military aircraft, and designed to meet the unique power needs of unmanned aerial systems (UAS) and ground systems.

The VXR Series uses VPT’s patent-pending advanced packaging technology, which incorporates EMI shielding and dual-sided thermal conduction. The integral epoxy encapsulated packaging is highly resistant to chemical, solvent, and salt environments and is compatible with high-volume manufacturing processes including wave solder, cleaning solvents, high-pressure sprays, and aqueous wash, officials explain.

“The VXR Series of products is reliability and efficiency focused, utilizing a low-noise, fixed frequency wide input voltage range topology,” says Jeremy Ferrell, VPT’s manager of standard product engineering. “We achieved this high efficiency over a wide input voltage range with a proprietary precision-controlled synchronous rectification topology. The high-efficiency design in-turn reduces the thermal management requirements.

“We also incorporated a proprietary control loop design that provides a fast transient response without the use of optoisolators,” Ferrell adds. “For customers with noise sensitive applications, we developed the VXR EMI Filter Series with current ratings from 2 to 20 Amps that were specifically designed to meet specific MIL-STD-461 and DO-160 conditions when used with our VXR Series DC-DC Converters.”

VPT Inc., part of the HEICO Electronic Technologies Group, provides DC-DC power converters, EMI filters, and custom engineering services for avionics, military, and space applications. Every day, global organizations like NASA, Lockheed Martin, Boeing, BAE Systems, the United States Air Force, and many more depend on quality solutions from VPT to power critical systems, officials say.

HEICO Corporation (NYSE:HEI.A) (NYSE:HEI) is engaged primarily in niche segments of the aviation, defense, space, and electronics industries through its Hollywood, Fla.-based HEICO Aerospace Holdings Corp. subsidiary and its Miami-based HEICO Electronic Technologies Corp. subsidiary.
