DC Solid State Power Controller Module
Description:
This Solid State Power Controller (SSPC) Module is the electronic equivalent to an electromechanical circuit
breaker with isolated control and status. It is designed to operate with minimal heatsink requirements. It is a
microcontroller-based Solid State Relay rated up to 50A, and designed to be used in high reliability 375V DC
applications. These modules have integrated current sensing with no derating over the full operating
temperature range.
This product is programmable with a simple jumper configuration connector in steps as 30A / 40A / 50A.
The product series also allows the programming of the Instant Trip level at three different levels: 150A, 200A
and 50A. The Battle Override that allows the protection to be turned off is a standard option.
