The POWRSOFT Controller is designed to soft start RONK rotary phase converters. By reducing the normal starting inrush on the single phase line by up to 50%, larger rotary converters may be used on utility single phase lines for irrigation systems and other loads when three phase is not available.
Built to work exclusively with RONK rotary phase converters. These units can be retrofitted into an existing RONK converter installation.
The reliability and safety of electrical systems have never been more crucial. RONK's American-designed and assembled products are durable, efficient, and built to last for decades.
