Industrial ASR-90RA Variable Solid State Relay

With a 90 A rating and an integrated potentiometer, the ASR-90RA Variable Solid State Relay provides proportional, phase-angle control of AC resistive loads for industrial heating and power-regulation applications. It is designed for silent operation and longer service life compared with electromechanical relays, suitable for use in electric heaters, ovens, heat sealers, plastic processing equipment, and other temperature-control systems where an adjustable power output is required. Key specifications include input voltage range 80-250 VAC; output voltage range 24-480 VAC; 50/60 Hz; optical isolation; panel-mount housing; cooling via external heat sink; load type: primarily resistive; control method: integrated potentiometer adjustment; intended for indoor industrial environments.
