28V DC Solid State Power Controller Module
Description:
These high power Solid State Power Controller (SSPC) Modules are designed to operate with minimal losses
and heat-sinking / airflow. They have an isolated case easing the installation process. High current bus bar
terminals are used to provide good, low-drop interface for the high current input / output. They are
microcontroller-based Solid State Relays rated up to 150A designed to be used in high reliability 28V DC
applications. These modules have integrated current sensing with no de-rating over the full operating
temperature range. These modules are the electronic equivalent to electromechanical circuit breakers with
isolated control and status.
This series is supplied in 2 SSPC current ratings of 150A and 130A.
SPDC150D28: 150A current rating
SPDC130D28: 130A current rating
