Soft Starts

A Soft start motor is a device used typically with electrical AC motors.How do they work?They work by helping reduce the torque and load in the power up and electrical current surges that are typical with motors during their start-up phase. The soft start only does this temporary however as it is only needed primarily during start-upFeatures and benefits:Can control multiple phases of power upControl of starting toque in machineryMotor power ratings ranging up to 700 kW and aboveInline contactors are not necessary if the machine it is used on is electrically isolatedControl starting times of the soft startVoltage boost functions available to control over toqueCan be mounted to DIN, panels or simply snap on capabilities Where might I use one?Smaller size cranesAutomatic doors/gatesFans or pumpsConveyor beltsCompressors
