BQXR-Mining Explosion-proof motor soft starter

Products Features: 

1. Applicable Scope
Soft starter is with intelligent control box, compare with the traditional “star-delta” starting equipments, it can start motor in agradual and smooth way, reduce the impact on the power grid to raise the performance of the motor, which is a good solution to the impact of the machinery and equipment when the motor starting. Besides, it has the protection functions and intelligent communication functions. It can be widely used in adhesive tape transport, fan, pumps and other motor control.

2. Function Features
Easy to operate, simple parameters
LCD display showing voltage, current, fault and easy for maintenance
Perfect advanced control method: electric start-up with voltage slope, the option of the current closed-loop slope
The protection types: under voltage, over-voltage, overload, lack of phase, over load, line fault, blocking switch, thyristor failure.
With intelligent communication interface
With remote control, near control, centralized control the past control and a variety of control.
Explosion-proof shell is quick-opening, reliable mechanical linkage between isolating switch and explosion-proof shell.
The device type is rail type. The body is interchangeable; connector connections control circuit, easy for operation and
maintenance.
