GR Series 1-7KW 3-phase electric motor forward and reverse rotation SSR
Introduction
This is a newly-designed SSR used for the control of forward and reverse rotation of electric motor; it is suitable for 3-phase inductive electric motor (P≤7000Wa). The built-in electronic lockdown circuit can effectively avoid the simultaneous conduction of SSR forward switch and reverse switch. The LED display the rotation direction of the 3-phase motor, green LED indicates forward direction and red LED indicates reverse direction. Its adoption of thyristor inverse parallel technology and built-in pressure responsive resistor over-voltage absorbing circuit has a strong over-voltage enduring capability, durable and stable.
Two models are available for this product, one choice is 2-controls of 3-phase, two terminals connect to the thyristor phase-shift switch, the other one is SC (short circuited). Another choice is 3-controls of 3-phase, all the 3 terminals connect to thyristor switch, which has a better performance than the former one.
