DC and AC Reversing Solid State Contactor
Features:-
- Designed to allow operation and reversing of the rotating direction of three phase motors.
- Offers a modern alternative to conventional electromechanical three phase reverser.
- Provides isolation through very high immunity Opto-couplers.
- Maximum current is 75 A,
- Models for 2KW, 3KW, 5.5KW, 7.5KW motor under 480 VAC or 600 VAC to be driven at high switching frequencies while taking account of starting currents.
- Built- in Interlocking Included.
- DC and AC models available
