Carlo Gavazzi launched its new RGTS Series single-phase motor soft-starters. They can control 120 or 240VAC induction motors up to 25A / 3Hp.

 

The RGTS Series is a fully solid state solution. Wire bonding technology reduces the thermal and mechanical stresses of the output chips resulting in a longer lifetime, according to the company. The RGTS is a very simple soft starter requiring just two user adjustments. The motor ramp-up time, and initial torque, can be independently adjusted via the built-in potentiometers. The green LED indicates the supply voltage presence. The ramp-up and full-voltage indication are provided through an orange LED. The RGTS does not require a dedicated control signal. Hence less wiring is involved. Despite its simplicity, the RGTS solution that can help to reduce motor starting current by 40 percent compared to a direct on-line start.
