EPM 109 Series Solid State Power Controller

This LEACH Solid State Power Controller (SSPC) employs the latest micro-controller and Power FET technology incorporated into a Printed Circuit Board (PCB). The EPM-109 features non-derated switching for all types of load, while protecting against overload and short circuit. It features an extensive Built-In-Test (BIT) that verifies all critical functions at start-up and during operation. It is designed for operation in 28 VDC systems with a full rating of 3 channels of 7.5 Amps and 2 channels of 12 Amps.
