VPT Adds Industrial Level VHR Series DC-DC Converter Line

VPT now offers its VHR Series of industrial level DC-DC converters and EMI filters, available in models ranging from 5W to 100W.

The VHR Series of DC-DC converters provides customers with VPT’s renowned levels of product reliability for powering non-flight-critical programmes in military, avionics, and unmanned systems, as well as manufacturing equipment and controls.

"Engineers aren’t looking for a ‘one converter fits all’ solution, so VPT supplies a wide range of high-reliability standard products that best match specific application requirements," said sales and marketing vice president Monty Pyle.

"Just as space programmes utilise converters designed for rigid MIL specs and radiation exposure, programmes on the other end of the spectrum are aligned to solutions, like the VHR Series, that are cost effective and highly reliable without requiring the extensive environmental screening that is necessary for flight-critical programmes."

The VHR Series design leverages VPT’s decades of experience in proven military, aerospace and defence solutions. For budget-driven programmes, the series offers a wide input voltage range for nominal 28V input, an average 85% efficiency and low input and output ripple for reliable operational success, even in rugged environments.

Designed to operate at full-load over a wide temperature range of -40°C to 100°C, the VHR Series also offers fixed frequency operation, soft-start, magnetic feedback, inhibit and current-limit protection. Additionally, the VHR Series includes companion EMI filters ranging from 1A to 20A.
