The SPMU is a multi-channel 28VDC power controller that is capable of power management and diagnostics. The SPMU is conduction cooled, microcontroller-based, Solid State Power Controller (SSPC), designed with Line Replaceable Module (LRM) characteristics for military and commercial applications.
Each of the 32 channels of the SPMU has software programmable current ratings and can operate in groups. The design has integrated current, temperature and voltage sensing and no derating over temperature. Parameter measurements, system status information, and control commands are implemented over CAN and Ethernet bus interfaces.
