TECHNICAL DATA

DATASHEET 5104, Rev D

28V DC Solid State Power Controller Module

Description:

This Solid State Power Controller (SSPC) Module is designed to operate without any heatsink requirements.

This is microcontroller-based Solid State Relays rated up to 35A designed to be used in high reliability 28V

DC applications. This module has integrated current sensing with no derating over the full operating

temperature range. This module is the electronic equivalent to electromechanical circuit breakers with

isolated control and status.
