DATASHEET 6041, Rev -
DC Solid State Power Controller Module
Description:
This SPDP100D375 is a Solid State Power Controller (SSPC) Module; 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 100A, 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 60A / 80A / 100A. The product series also allows programming the
Instant Trip level at three different levels: 95A, 128A and 161A. The Battle
Override, that allows the protection to be turned off, is a standard option.
