A high-efficiency, compact DC-to-DC converter designed to operate in LEO environments that provides a regulated, isolated, 12V rail suitable for powering the full suite of CesiumAstro communications products.
The CesiumAstro PCU-1C28 includes a fixed-frequency converter with integrated filters and protections as well as a digital interface for telemetry in a credit-card-sized footprint. Each module is parallelable with other CesiumAstro PCUs for higher output power or hot redundancy.
Use as a stand-alone power converter or combine with other CesiumAstro modules for a system that works out-of-the-box.
