Nidec D3-14-0255-N Soft Starter Unit

Feature & Principle

This soft starter adopts thyristor voltage regulation control. It gradually increases motor terminal voltage during startup to reduce starting impact current, supports soft stop function. It integrates overload, phase loss and overheat protection, communicates with PLC via fieldbus for remote monitoring.
