Compact, digital AC semiconductor motor controller. When used on a typical 400VAC supply, this controller can soft-start and soft-stop 3-phase motors up to 22kW (30HP). When connected In Delta and up to 15kW (20HP) when connected In Line, all 3-phases are switched. Starting and stopping time as well as initial torque can be independently adjusted by potentiometers on the facia. A version adapted for starting Scroll Compressors is also available. This device does not include internal bypass relays but provides a relay contact to help energize an external bypass contactor.
