CMC-HX The Intelligent AC380V Motor Soft Starter

CMC-HX soft starter is a new type of intelligent asynchronous motor starting and protection device. It is a motor terminal control device that integrates starting, display, protection and data acquisition. More complex control functions can be achieved with fewer components. The Chinese and English interface display makes the operation easier. At the same time, the CMC-HX soft starter integrates a current transformer, so users do not need to externally match.

First, the role

Reduce the starting current of the motor, reduce the distribution capacity, avoid the investment of capacity increase; reduce the starting stress and prolong the service life of the motor and related equipment; smooth start and soft stop avoid the surge problem and water hammer effect of the traditional starting equipment; A variety of starting modes and a wide range of current, voltage and other settings, can adapt to a variety of load conditions; improve the reliable protection function, more effectively protect the motor and related equipment;

Second, the characteristics

SCR trigger

Closed-loop control algorithm SCR closed-loop control, designed for standard and heavy duty loads. The user can select the current limit start and the voltage ramp start according to the load condition to achieve a smooth torque-free oscillation start effect.


load application

There are ten kinds of load types built in the parameters for the user to choose, and the starting control curve is provided for each type of load, so that the soft start and the load are matched to achieve a good starting and stopping effect.


Multiple starting and parking methods

Voltage exponential curve, voltage linear curve, current exponential curve, current linear curve, and programmable kick start torque and starting current limit can be applied in each mode. According to different loads, the corresponding starting curve can be selected to achieve a good starting effect. A variety of parking modes, programmable soft parking, free parking, brakes, pump stop. The basic algorithm makes the motor start and stop more accurate and smooth.


advanced communication function

Standard Modbus RTU communication. Optional Ethernet/GPRS communication module facilitates user network connection control and improves system automation and reliability.


analog signal control

The user can input 4-20mA or 0-20mA standard signal, and can set the upper and lower limits of the analog quantity to realize the start and stop control and alarm of the motor. Data (pressure, temperature, flow, etc.) can also be transmitted via a soft starter. With 4-20mA or 0-20mA standard analog signal output function.


All refractory materials

Below 90KW is a fully molded shell structure, which is made of 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-resisting and anti-corrosion properties.


External panel

The panel can be externally led to the operating surface of the device through the fuselage interface for remote operation.


strong anti-interference

All external control signals are optically isolated and have different levels of noise immunity to suit industrial environments.


double parameter function

It has two basic parameters to control two motors of different powers.


power frequency

Adaptive power frequency 50/60Hz adaptive function, convenient for users.


dynamic fault memory

10 faults can be recorded. It is easy to find the cause of the malfunction.


perfect protection function

The whole process detects current and load parameters, and has microcomputer protection functions such as overcurrent, overload, underload, overheat, phase failure, short circuit, three-phase current imbalance, phase sequence detection, and frequency error.


friendly man-machine interface

It adopts LCD liquid crystal display panel and has two display interfaces in Chinese and English, which makes programming and parameter adjustment more convenient.
