Phase-angle control adjusts output continuously each half-cycle — suitable for precise temperature regulation. Zero-cross control switches complete half-cycles on and off — reduces electrical noise and suits transformer loads.

Select based on load type, supply voltage, control method (phase-angle or zero-cross), and current rating. Choose a current rating at least 1.3× your actual load current to ensure reliable continuous operation. Send us your load specifications for a free selection recommendation.

Yes. Supported control signal inputs include 0–10V, 4–20mA, and potentiometer, compatible with PLC outputs and PID temperature controllers.

Overcurrent, overvoltage, and overtemperature protection. Specific features vary by model — contact us for details.
