HFSR Soft Starter

TANSWAVES HFSR SOFT STARTER manufacturers -M/s Sakthi Power Innovatives an ISO 9001:2015 Certified Company is engaged in Designing and Manufacturing of Soft Starter with Air Core Series Reactor.Our starters are step less, reduced voltage start which ensures a constant low starting current and incremental voltage torque. This helps in optimizing the power source ie, transformer or generator size. Optimized power system gives savings capital in cost and savings in revenue expenditure due to increased efficiencies. Our soft starters are designed as per the IS 5553 (part 3)/ IEC 60289/60076 working on the principle of Series Reactor for current limiting of 3 phase motor”. Our Soft Starter shall be of air core design for smooth linear acceleration and high efficiency, Natural Air Cooled [meeting all the specification of standard IS 5553[part3] IEC60289/60076] and shall not generate humming noise while starting.

We are glad to provide “The customized Solution as per clients technical requirements’’.
