A high-efficiency, compact, DC to DC converter designed to operate in Low Earth Orbit (LEO) environments that provides a regulated, isolated, 12V rail suitable for powering the full suite of Cesium communication products.
The Cesium 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 Cesium PCUs for higher output power or hot redundancy.
Use as a stand-alone power converter or combine with other Cesium modules for a system that works out of the box.
