Autonics SR1-1425 is a 25 A single-phase solid state relay (SSR) from the SR1 series with detachable heat sink. It switches heaters silently and without contacts from the SSR (DC) output of a PID controller. In a 400 VAC phase-to-phase connection, the rated current corresponds theoretically to approx. 10.0 kW of resistive load.
