The POWRSOFT® is a specialized soft starter designed to reduce the inrush on the 1Ø utility lines for RONK rotary phase converters. By reducing inrush currents and minimizing mechanical and electrical stress on the system, POWRSOFT enhances the longevity and efficiency of phase conversion applications.
This unit works exclusively with RONK rotary phase converters, providing a controlled ramp-up of power to ensure smoother motor operation. While it does not directly affect the load equipment, POWRSOFT helps improve the reliability of power conversion by reducing voltage fluctuations and electrical disturbances during startup.
Ideal for applications where consistent and stable power delivery is critical, the RONK POWRSOFT offers a cost-effective and low-maintenance solution for enhancing rotary phase converter performance. Designed with industrial durability and seamless integration in mind, it ensures that your power system operates with maximum efficiency while extending the lifespan of your rotary phase converter.
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.
