A voltage controller is similar in function to a soft starter. In difference to the soft starter, which always increases the motor voltage up to the nominal voltage, the voltage controller remains in the partially or fully modulated range, depending on the specified setpoint. This allows the user to adjust the motor torque over a wide range. It can also be used as a power controller for electric heaters.
Single-phase voltage controllers 1,5 – 18 A
Three-phase voltage controllers 6 A
