General Introduction

The ARF50 series Motor Generator Sets are specially designed for the applications requiring high-quality 400Hz power source at the locations with 50Hz grid line. When connected to a 50Hz power source, it outputs the clean 400Hz electricity isolated from switching transients, voltage fluctuations and power line noise.

The ARF50 MG sets are rated for continuous duty Eachproductconsistsofone4-pole synchronous motor and one 24-pole brushless synchronous generator.Themotorand the generator are mounted on the same shaft. The units work at the speed of 2000rpm, and output 400Hz from no load to full load. Lightning Protection Device is included.d.
