VPT Adds VXR Series to Hi-Rel COTS Product Line

Wide Input Voltage Range and Advanced Packaging Technology for Superior Operation in Harsh Environments.

VPT, Inc. (VPT®), a HEICO company (NYSE:HEI.A) (NYSE:HEI), launched its new VXR Series of DC-DC Converters and EMI Filters today at the annual Association for Unmanned Vehicle Systems International (AUVSI) conference being held in Atlanta, Georgia. The VXR Series of DC-DC Converters and EMI Filters represent VPT's most advanced offering of its extensive line of high-reliability COTS DC-DC Converters and accessory products. Available in models ranging from 7 to 100 Watts with an industry leading wide continuous input voltage range from 9 to 60 VDC and transient operation from 6 to 80 VDC, the VXR Series is optimized for a broad range of applications from military ground vehicles to commercial and military aircraft, including the unique power needs of unmanned aerial and ground systems.

The VXR Series utilizes VPT's patent-pending advanced packaging technology. This proprietary encapsulation process incorporates EMI shielding and dual-sided thermal conduction. The integral epoxy encapsulated packaging is highly resistant to chemical, solvent and salt environments and is fully compatible with high-volume manufacturing processes including wave solder, cleaning solvents, high-pressure sprays and aqueous wash.

"The VXR Series of products is reliability and efficiency focused, utilizing a low-noise, fixed frequency wide input voltage range topology," said 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 added, "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."
