Cmc-mx built-in bypass motor soft starter is a voltage regulating and current limiting intelligent asynchronous motor soft starter based on trigger closed-loop algorithm. Power electronic circuit detection and advanced closed-loop control algorithm make the starting and protection functions. The contact of built-in bypass contactor adopts magnetic holding contactor, which is different from other external bypass AC contactors in long-term live operation mode. This product has no noise, no electromagnetic pollution, no spark and is green.

1. Multiple starting modes

The user can select current limiting start and voltage ramp start, and programmable jump start and starting current limit can be applied in each mode. Meet the on-site requirements and achieve good starting effect.

2. Reliability

The microprocessor digitizes the signals in the control system to avoid excessive adjustment of the previous analog circuit, so as to obtain good accuracy and execution speed.

3. Strong anti-interference

All external control signals adopt photoelectric isolation and are set with different anti noise levels, which is suitable for use in industrial environment.

4. Simple adjustment method

The control system has a wide range of applications, simple and intuitive mode adjustment, and can match all kinds of different control objects through various function options.

5. Optimized structure

The compact internal structure design is particularly convenient for users to integrate into the existing system, saving the cost of current transformer and bypass contactor for users.

6. Power frequency adaptation

The power frequency 50 / 60Hz adaptive function is convenient for users.

7. Analog output

4-20mA current output function, convenient for users.

8. MODBUS-RTU communication

During network communication, 32 devices can be connected. Users can set baud rate and communication address to achieve the purpose of automatic communication. The setting range of communication address is 1-32, and the factory value is 1. Communication baud rate setting range: 0, 2400; 1、4800； 2、9600； 3、19200； The factory value is 2 (9600).

9. Perfect protection function

A variety of motor protection functions (such as overcurrent, input and output phase loss, thyristor short circuit, overheating protection, leakage detection, electronic thermal overload, internal contactor fault, phase current imbalance, etc.) ensure that the motor and soft starter will not be damaged in case of fault or misoperation.

10. Easy maintenance

The monitoring signal coding system composed of 4-digit digital display can monitor the working condition of system equipment for 24 hours and provide rapid fault diagnosis at the same time.
