DC Solid State Power Controller Module
Description:
The Solid State Power Controller (SSPC) Module is a microcontroller-based Solid State Relay rated upto
25A designed to be used in Army, Air force and Navy in 28V DC applications. This module has integrated
current sensing with no derating over the full operating temperature range. The module is the electronic
equivalent to an electromechanical circuit breaker with isolated control and status.
This series is supplied in 3 product families covering 9 current ranges:
