| SENSITRON SEMICONDUCTOR Technical Data Datasheet 4119, Rev. B SPD-8A115 AC/DC Solid State Power Controller Module Description: The Solid State Power Controller (SSPC) Module is a microcontroller based Solid State Relay, designed to be used in Aircraft or Navy in 115VAC/150VDC applications. This module has integrated current sensing and over current / over temp protection. The module is equivalent to a DPST relay with a common single side isolated control.
