Frontgrade Launches Space-Optimized PSM28 Power Supply Module for High-Reliability SpaceVPX Systems

Colorado Springs, CO (September 9, 2025) - Frontgrade Technologies, a leading provider of high-reliability electronic solutions for space and national security missions, today announced the release of the PSM28 VPX Power Supply Module, an advanced, high-efficiency solution designed to power next-generation space systems with unmatched reliability and flexibility.

The PSM28 VPX, built on Frontgrade’s proprietary MAMBA™ architecture and utilizing Space GaN technology, delivers seamless conversion from 28V to a regulated 12V output. This compact 3U SpaceVPX power module is engineered to meet the stringent performance and environmental requirements of space missions, offering up to 24A peak current and 150W nominal (288W peak) output to support spacecraft processing systems and payloads.

Engineered for modular scalability, the PSM28 VPX supports parallel operation with active current sharing, enabling flexible power expansion across Frontgrade’s Reconfigurable Processing System (RPS-PS) and RPS-9X-PS platforms. The module features a main 12V rail and six switched 12V outputs, each capable of delivering up to 100W continuous power, streamlining distribution for plug-in cards and ensuring mission-critical redundancy.

“The PSM28 VPX is more than a power converter, it’s a scalable building block for mission success,” said Lorne Graves, Chief Technology Officer at Frontgrade. “It brings a smarter, more fault-tolerant approach to spaceborne power systems, while staying compact and easy to integrate into SpaceVPX environments.”

Equipped with Frontgrade’s UT32M0R500 ARM Cortex-M0+ microcontroller, the module enables real-time health monitoring, output control, and interface flexibility via IPMI commands. Designed to enable VITA 78.0 SpaceVPX systems, the PSM28 VPX ensures interoperability, radiation tolerance, and robust protection, empowering space system designers to confidently deploy in demanding orbital conditions.
