ADX Series, Extreme Duty - This SMART Series Phase Converter is manufactured in the USA by American Rotary and will convert 1 to 3 Phase power and provide 100% power for 208-250v equipment. The ADX series phase converters have current control to provide consistent torque while starting high inertia, extremely hard starting loads, yet are precise enough for CNC applications. Best for: High Inertia/friction loads such as pumps, fans, compressors, blowers, dust collectors and fly wheels. 

NOTE: for AIR COMPRESSORS: American Rotary recommends sizing 3:1 with Quincy, Ingersoll Rand, and Atlas Compco OR if the air compressor uses a high efficiency motor. (ex. 10HP compressor = ADX30)
