VPT High-Reliability Power Conversion Products for Military and Avionics Applications


VPT is a global provider of critical power conversion solutions for avionics, military, and space applications.

VPT is part of the HEICO Electronics Technologies Group (NYSE:HEI.A) (NYSE: HEI). HEICO’s customers include a majority of the world’s airlines and airmotives, as well as numerous defence and space contractors.

Avionics and military DC-DC converters

VPT’s isolated DC-DC converters, along with its family of non-isolated, synchronous, buck regulated, point-of-load DC-DC converters create an efficient and cost-effective power system for saving electronic board space, weight and heat.

VPT offers product lines that are ideal for military aircraft, weapons systems and unmanned systems.

With a wide variety of power conversion products, high efficiencies, wide temperature ranges and DLA Standard Microcircuit Drawings (SMDs) for most models, it is easy to match VPT’s power conversion products to a programme’s military specifications.

Ranging from 1w to 120w with a military temperature range of -55°C to 125°C, VPT’s DV series of products are proven in military and avionics applications. They are designed to meet rigid military specifications and 100% hermetic with a host of circuit protection features.

High-reliability rugged power DC-DC converters

VPT’s VXR series of rugged high-reliability DC-DC converters and electromagnetic interference (EMI) filters are optimised for a broad range of applications. These include military ground vehicles, manned and unmanned aircraft that endure severe vibration, shock, temperature cycling and other adverse environments.

Furthermore, the VXR series features VPT’s patent-pending, epoxy-encapsulated V-SHIELD™ packaging, which is highly resistant to chemical, solvent and salt environments. This enables it to be fully compatible with high-volume manufacturing processes including aqueous wash, high-pressure sprays, cleaning solvents and wave solder.
