VPT Announces the FLX Series, a Highly Scalable DC-DC Converter Power Solution for Mission-Critical Applications

BLACKSBURG, Va., Sept. 16, 2026 /PRNewswire/ -- VPT, Inc. (VPT^®), a HEICO company (NYSE: HEI.A) (NYSE: HEI) and leading provider of high-reliability power conversion solutions for military, avionics, and space applications, announces the launch of the FLX Series, a configurable DC‑DC converter power solution engineered for mission‑critical applications requiring robust, turnkey power conversion.

The FLX Series integrates VPT's proven DC‑DC converters and EMI filters into a rugged, scalable housing designed for the harshest environments. This configurable framework enables engineers to accelerate system integration by consolidating multiple converter modules into a single, qualified assembly.

"The new FLX Series is highly scalable, optimizes SWaP, and delivers exactly the power and voltages a customer's system needs," said Kevin Seaton, Advising Engineer at VPT. "We designed this series for rugged environments and favorable lead times, each assembly is prequalified to Military Standards and offers configurable output rails through preferred connector interfaces for streamlined power integration."

Supporting standard 28 V, 50 V, and 270 V bus voltages, the FLX Series delivers 1 W to 5,000 W of output power with efficiencies up to 90%. Each unit is configurable with multiple outputs, enabling engineers to consolidate multiple converter modules into a single, qualified assembly that simplifies system integration, saves engineering time, and ultimately reduces design risk.

The FLX Series is built to perform in demanding conditions including high shock, vibration, and wide temperature ranges. Units operate continuously from -55°C to as high as +110°C with no power derating, making them suitable for airborne, ground, and space platforms. For space applications, radiation capabilities range from radiation tolerant (30 krad(Si) / 42 MeV) to radiation hardened (100 krad(Si) / 85 MeV), depending on the selected converter model series.

Key Features:

• Flexible, turnkey power solution
• Integrated EMI filter (MIL‑STD‑461)
• Scalable output power up to 5,000 W
• 3 mechanical configurations (vertical, horizontal, and stacked)
