11kW ~ 600kW 3 Phase AC electric Motor Speed Controller Soft Starter
Themotor soft starters use thyristors for controlled reduced voltage motor starting and stopping. These low voltage soft starters then switch to internal contacts for efficient running at the rated speed.

Technical characteristics
1. Unique SCR trigger closed-loop control algorithm
Unique SCR closed-loop control, specially designed for standard and heavy loads. The user can select the current limit start and the voltage ramp start according to the load condition to achieve an absolutely smooth torque-free oscillation start effect.
2.Control accuracy, real-time efficiency
High-performance CORETX-M3 32-bit core CPU for center control, fast speed, high precision, strong anti-interference ability
3.Beautiful appearance
Patented main circuit three-in and six-out structure, built-in current transformer scheme, convenient wiring and high reliability
4.Optional standard MODBUS-RTU protocol
5.Integrated advanced protection
It has protection functions such as input and output phase loss, overload, overcurrent, phase current imbalance, thyristor over temperature, etc., to protect the motor and related equipment in all directions.
6.Full refractory
90kw or less is a fully molded shell structure, processed with flame-retardant ABS material. The upper cover of 90KW and above is made of plastic shell structure, and the main frame is made of aluminum-zinc plate material. It has heat resistance and corrosion resistance.
7.External lead panel
The panel can be externally led to the operating surface of the device for remote operation through the fuselage interface, which is convenient for on-site use.
8.Simple maintenance
A monitoring signal coding system consisting of a 4-digit digital display that monitors the operating conditions of system equipment 24 hours a day, while providing fast fault diagnosis
