Solid State Relay Controller

Phillips & Temro Industries has launched a solid state relay controller (SSRC) for diesel engines. The company said the new SSRC is an application-specific product that performs supervisory and diagnostic functions to safely switch high electric current and quickly protect against overload and short circuit conditions.

The controller has no moving parts and offers low power consumption, long life, small size, fast switching speeds, shock and vibration resistance, short circuit protection, and diagnostic feedback, said the company. It uses CAN communications or discrete logic control depending on application requirements and has electric current ratings up to 400A 12V or 200A 24V.

Initial product applications include quick start air intake heaters that require high current control and safety monitoring to provide faster start times on diesel engines. PTI said it is currently exploring additional applications, including power generation and off-road.
