AC/DC solid-state power control module

explain:

Solid state power controller（Aviation SSPC）Module is a microcontroller based solid-state relay designed for aircraft or naval 115VAC/150VDC applications. This module integrates current sensing and overcurrent/overheat protection. This module is equivalent to a DPST relay with a common single-sided isolation control.

This product complies with the documents and standards.
