SC764110 is a single-phase power solid state relay designed for motor control and phase angle control applications. It features a 4-30VDC control input with a control current range of 3-30 mA and an input internal resistance of 1000 O, providing flexible control options. The output stage delivers 24-520VAC at 50A nominal current (AC-51 rating) with random synchronization, a peak voltage rating of 1200V, and an on-state voltage drop of 1.4V at nominal load current. The relay exhibits fast switching characteristics with a turn-on time of 100 µs maximum and turn-off time of 10 ms maximum, operating across a frequency range of 0.1-440 Hz. It provides 4000V RMS input-output isolation and is designed to be mounted on a heatsink for thermal management, making it suitable for demanding industrial control applications requiring reliable AC power switching.
