VPT, a HEICO company focused on high-reliability power solutions for military, avionics, and space systems, has launched its new FLX Series of configurable DC-DC converters. Designed for mission-critical applications, the platform combines power conversion and EMI filtering in a rugged, scalable package, helping simplify the integration of power subsystems.
The FLX Series supports 28V, 50V, and 270V input buses and delivers power levels ranging from 1W to 5,000W, with efficiency reaching up to 90%. Its flexible output configurations allow multiple conversion functions to be combined within a single qualified assembly, reducing the number of separate modules and easing system-level integration.
An integrated EMI filter supports MIL-STD-461 requirements, while selected configurations can also meet MIL-STD-704, MIL-STD-1275, and DO-160 requirements. The series is offered in vertical, horizontal, and stacked mechanical configurations, giving designers greater flexibility for systems with varying space and thermal limitations.
Built for demanding environments, FLX converters can operate continuously from −55°C to +110°C without power derating. This makes them suitable for airborne, ground, and space applications. Built-in features include current limiting, short-circuit protection, undervoltage lockout, remote sensing, load sharing, and fixed-frequency operation. The converters also operate without optocouplers.
For space applications, radiation performance varies by model. Available options include radiation-tolerant versions rated to 30 krad(Si) and 42 MeV, as well as radiation-hardened versions rated to 100 krad(Si) and 85 MeV.
The modular FLX architecture allows power systems to be tailored to specific voltage, power, and mechanical requirements while leveraging qualified converter technologies. VPT manufactures these systems at facilities certified to SAE AS9100, J-STD-001 with the Space Addendum, and IPC-A-610 standards.
The FLX Series is currently available, with VPT offering additional configurations and feature options to meet application-specific requirements.
