Soft-Starter - EUROTHERM PROCESS - #1

Soft-Starters are electronic starters designed to accelerate, decelerate and protect three-phase induction motors, controlling the voltage applied on the motor. The ERSSW05 Plus Micro Soft-Starters, with Digital Signal Processor (DSP) control have been designed to supply an excellent performance during the starting and stopping of electric motors with excellent cost/benefit ratio. The Operator Interface allows easy parameter setting, simplifying the start-up and operation activities. The ERSSW05 Plus Micro Soft-Starters are compact, optimising the space in electrical panels. The ERSSW05 Plus incorporates all protections for the driven motor.
