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.

VPT products are manufactured in a MIL-PRF-3853 Class H and Class K certified facility.
The F-35 Lightening II implements VPT parts.
VPT components are featured on-board the Predator.
VPT parts are on-board Boeing’s Apache Helicopter for high reliability.
V-SHIELD® epoxy packaging includes dual-sided thermal conduction and internal EMI shielding.
Most VPT products ship directly from stock.
VPT parts help power the optical Infrared Search and Track System developed by Lockheed Martin.

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, VPT’s patented epoxy encapsulated V-SHIELD® packaging is also highly resistant to chemical, solvent and salt environments, making it fully compatible with high-volume manufacturing processes such as wave solder, cleaning solvents, high-pressure sprays and aqueous wash.

Advanced power conversion technology benefits

VPT’s continual advancements in power conversion technology deliver many unique advantages across its product lines, including:

  • Maximum reliability, thick-film, hybrid technology
  • Innovative, rugged, high-reliability architecture
  • Proprietary epoxy encapsulation package availability
  • Full operation over wide temperature ranges
  • Excellent EMI performance
  • High-power densities
  • Lightweight

Rugged environmental screening

Each VPT product line offers several grades of environmental screening.

Depending on the product series selected, possible tests performed include:

  • Non-destructive bond pull
  • External and internal visual: constant acceleration and radiography
  • Particle impact noise detection (PIND)
  • Stabilisation bake and temperature cycling
  • Electrical: pre burn-in electrical, burn-in and 100% final electrical
  • Hermeticity

White Papers

  • VPT Series DC-DC Converters and Power Accessory Modules

    Military and other high reliability system designers are under continual pressure to reduce costs and development times. Following the DoD’s “COTS Directive,” one of the primary methods of achieving these goals is to forego military standards and specifications, and instead use the best available commercial practices, standards, components, and hardware.

  • High-Reliability Power Conversion

    When your programme needs true military-grade high-reliability DC-DC converters, EMI filters and other power accessories qualified to MIL-PRF-38534 Class H and Class K, count on the proven products from VPT's DV Series.
