Only Benshaw has designed, built and supports more than 40,000 solid state starters, from 2,300 volts to 15KV, for applications ranging from pumps, compressors and chillers to fans and blowers, crushers, chippers and conveyors; for every motor type: induction, synchronous, two-speed, reversing and wound rotor. The RediStart CFMVRMX series with MX3 technology is a fully integrated, programmable family of Class E2 load break/combination solid state starters. This integrated design includes control and power electronics, bypass and isolation contactors that reduce maintenance and operating costs when compared to other methods.

Advantages

• Protect machinery from failure and excessive maintenance caused by mechanical shock during starting or stopping. Solid State Starters provide smooth, stepless acceleration and controlled deceleration.

• Protect electrical systems from disruptive voltage drops and power outages caused by motor locked rotor inrush current. Solid State Starters precisely control the current ramp during start up.

• Protect mission critical motors from failure or unscheduled outages caused by machine or electrical system faults. The Solid-State Starter provides complete, high performance, coordinated line monitoring, motor control and protection.
