CMC-MX motor soft starter is a new type of motor starting and protection device for soft starting and soft stopping of standard squirrel cage motors. The product combines power electronic technology, microprocessor and automatic control.
It can start/stop the motor smoothly without steps, avoiding mechanical and electrical shocks caused by traditional starting methods such as direct starting, star/delta starting, and auto-decompression starting. Effectively reduce starting current and power distribution capacity and reduce investment.
The CMC-MX soft starter integrates current transformer and bypass contactor inside, and users do not need to equip it additionally.
1. Various starting methods
Users can select current limit start, voltage ramp start, and can apply programmable kick start and start current limit in each mode to meet the needs of the site and achieve a good starting effect.
2. High Reliability
The microprocessor digitally processes the signals in the control system, avoiding the excessive adjustment of the analog circuit in the past, so as to obtain good accuracy and execution speed.
3. Powerful Anti-interference Performance
All external control signals are optically isolated, and different anti-noise levels are set to adapt to use in industrial environments.
4. Easy Adjustment
The control system has a wide range of applications, the mode adjustment is simple and easy to observe, and various functional options can be used to match various control objects.
5. Optimized Structure
The compact internal structure design is particularly convenient for users to integrate into the existing system, saving the cost of current transformers and bypass contactors for users.
6. Self-adaption of power frequency
Power frequency 50/60Hz adaptive function, convenient for users.
7. Analog output
4-20mA current output function, user-friendly.
8. Advanced MODBUS-RTU Communication function
During network communication, 32 devices can be connected. Users can achieve the purpose of automatic communication by setting the baud rate and communication address. The communication address setting range is 1-32, and the factory default value is 1. The communication baud rate setting range is: 0, 2400; 1, 4800; 2, 9600; 3, 19200; the factory value is 2 (9600).
9. Perfect protection
A variety of motor protection functions (such as overcurrent, input and output phase loss, thyristor short circuit, overheat protection, leakage detection, electronic thermal overload, internal contactor fault, phase current imbalance, etc.) not be damaged.
10. Easy Maintenance
The monitoring signal coding system composed of 4-digit digital display monitors the working conditions of the system equipment 24 hours a day, and provides fast fault diagnosis at the same time.
