GENERAL:
Model 3G3RX2 series inverter is an open type AC Inverter with three phase input and three phase out-
put. It is intended to be used in an enclosure. It is used to provide both an adjustable voltage and
adjustable frequency to the ac motor. The inverter automatically maintains the required volts-Hz ratio
allowing the capability through the motor speed range. It is a multi-rated device and the ratings are
selectable according to load types by operator with key pad operation.
