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.
