VPT, part of HEICO, introduces the FLX Series DC‑DC platform, adding a configurable, high‑power option for harsh defense and space environments.

Rhea-AI Summary

HEICO (HEI), through its subsidiary VPT, has launched the FLX Series, a configurable DC‑DC converter power solution for mission‑critical military, avionics, and space applications. The FLX Series integrates VPT DC‑DC converters and EMI filters into a rugged, scalable housing supporting 28 V, 50 V, and 270 V bus inputs and delivering 1 W to 5,000 W of output power with efficiencies up to 90%.

Units offer multiple configurable outputs, three mechanical configurations, integrated MIL‑STD‑461 EMI filtering, and protection features such as current limit and short‑circuit protection. The assemblies operate continuously from –55°C to as high as +110°C with no power derating and include radiation‑tolerant and radiation‑hardened options for space platforms. The FLX Series is available now.

Analysis

HEICO shares were down 2.27% pre-publication, while three listed aerospace peers also declined; the FLX launch entered a predominantly negative peer backdrop rather than an isolated target move.

dc-dc converter technical

"launch of the FLX Series, a configurable DC‑DC converter power solution"

A dc-dc converter is an electronic device that takes direct current (DC) power at one voltage and changes it to a different DC voltage needed by other parts of a product, like stepping down battery power for small circuits or stepping up voltage for motors. Think of it as a pressure regulator for electricity; its efficiency, size, cost and reliability directly affect product performance, battery life, manufacturing cost and competitive position, which are important to investors.

emi filter technical

"integrates VPT's proven DC‑DC converters and EMI filters"

An EMI filter is a small electronic component that reduces unwanted electrical noise or interference generated by or entering a device, helping circuits run smoothly—think of it like a water filter that keeps grit out of a pipe. For investors, EMI filters matter because they affect a product’s reliability, compliance with safety and radio rules, production costs and supplier risk; problems with them can cause recalls, delays or added expenses.

mil-std-461 regulatory

"Integrated EMI filter (MIL‑STD‑461)"

A U.S. Department of Defense technical standard that sets limits and test methods to control unwanted electrical noise and sensitivity in electronic equipment, essentially a ‘noise-proofing’ and interference check so devices won’t jam one another or be knocked out by outside signals. For investors, MIL-STD-461 compliance is a practical gatekeeper: it can be required to win military or government contracts, affects product development and testing costs, certification timing, and the commercial reliability and marketability of electronic systems.

itar regulatory

"export license restrictions and regulations, which may include but are not limited to ITAR"

ITAR is a set of U.S. rules that control the export, import and sharing of military items, technologies and related technical data. For investors it matters because companies that make or handle controlled defense products can face strict licensing requirements, export bans, heavy fines, or lost contracts if they fail to comply—similar to a traffic cop that can stop or reroute a shipment, which can affect revenue, supply chains and company value.

radiation hardened technical

"to radiation hardened (100 krad(Si) / 85 MeV)"

Radiation hardened describes electronic parts or systems designed to keep working when exposed to high levels of radiation, such as from space, nuclear environments or certain medical equipment. Think of them as ruggedized devices with extra shielding and design tweaks so they don’t fail when hit by energetic particles. Investors care because these specialized components sell at higher prices, are critical for mission‑critical customers, and often command long contracts and higher barriers to competition.

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.
