Ronk Type 4SAC Add-A-Phase Power Converter for 1-15HP, 480V Motor
The Type SAC is an ideal converter for most air conditioning applications. Its high efficiency, high starting torque, ease of use in automated systems and the ability to provide balanced currents to motors allows it to operate 3-phase compressor (and fan) motors at full rated load. Multiple compressor/additional motor units can also be provided as needed. The Type 4SAC models convert a single phase 480 Volt to a three phase 480 Volt.
