Bypass Motor Soft Starter Fwi-ss3 Series 5.5kw-75kw 380v 3ph Application: Industrial

The Soft Starter we are offering is three-phase equipment without a built-in bypass contactor. This helps in adapting to the rapid development of electric power automation technology. It works well with this high-requirement technology as well. It detects the feedback voltage of the motor. It also helps in achieving closed-loop control. This ensures that the motor starts up under different conditions. Our Soft Starter reduces the starting stress of the motor and achieves maximum service life.



Intelligent external bypass soft starter is a latest start-up product, with long service life and low requirement for the environment. It designed and researched by our company with high technology, microprocessor as the core, combines SCR power drive, software and hardware protection, keyboard operation, torque control and fuzzy PID closed-loop algorithm and other advanced technologies. It integrates motor soft start, soft stop, light load energy saving and multiple functions into one. It is a newly built intelligent starter with international advanced level. This equipment has complete functions and implicit performance. It is widely used in the start-up process of transmission equipment, fans, pumps, compressors and most general applications.



1. Protection function: Motor protection during start-up, motor protection provides 12 kinds of protection functions after start-up and bypass, and there is no need to install other protection products, it helps to reduce investment of equipments.



2. Software keep upgrading: Abundant parameters. Adding Interval delay parameter to avoid motor damage caused by frequent start; Adding delay bypass switch parameter to prevent the contactor burning by the high-current switching.
