A soft-starter for three-phase induction AC motors, the RSGD needs only three settings. The self-learning algorithm adjusts the soft starter parameters to work with varying load conditions. It is active at every start to ensure that the motor always starts with the optimal settings. A current-balancing algorithm keeps the current unbalance to less than 15 percent. The line includes an option for Class 10 electronic overload. Phase-sequence protection can be enabled and disabled through the use of an integrated pushbutton. Torque controlled ramp-down provides smooth deceleration of motors. Features include operational current of 12 to 45 A; up to 40 hp rating; and operational voltage capacity of 220 to 600 VAC.
