Motor Soft Starter for 3 Phase AC690V 15-700kW Asynchronous Motors

CMC-HX soft starter is a new intelligent asynchronous motor starting and protection device. It is a motor terminal control equipment that integrates start, display, protection, and data collection. With the fewer components, user can achieve more complex control functions. The Chinese and English interface display makes the operation much easier. As CMC-HX soft starter is inbuilt with a current transformer, the external one is not needed.
 
Typical available loads: Centrifugal pumps, Hydraulic pumps, Axial fans, Centrifugal fans, Belt conveyors, Compressors, Crushers, Mixers, Ball mills, Thrusters
Availability:
  • CMC-HX_Smart Type
  • 3phase AC 690V±15% (Standard wiring), AC380V±15% (Internal delta connection)
  • Ordinary squirrel cage AC asynchronous motor
  • 15 ~ 700kW
  • Universal model, widely suitable for various mechanical loads. Typically used for fans, pumps, compressors, etc.

CMC-HX Soft Starter Technical Characteristics

  • Multiple start and stop modes

Voltage exponential curve start, voltage linear curve start, current exponential curve start, and current linear curve start. Programmable kick start torque and start current limit can be applied in each mode. According to the different loads, you can choose the corresponding start curve to achieve the appropriate starting effect. The device is provided with a variety of stop modes including programmable soft stop, free stop, braking, and pump stop. Unique basic algorithm makes the motor start and stop accurately and smoothly.

  • Perfect protective function

It detects current and load parameters, having overcurrent, overload, underload, overheating, phase failure, short circuit, three-phase current imbalance, phase sequence detection, frequency error and other functions.

  • Unique load application parameters

It is built-in ten kinds of load types for users to choose. It provides a unique start control curve for each type of load to make soft start match the load, so as to achieve the best start and stop.

  • Fireproof material

The product of below 90KW is in plastic structure made with inflaming retarding ABS material; for the product of 90KW and above, the upper cover is in plastic structure and main frame is made of aluminium-zinc plate with features of heatproof and corrosion resistance.

  • Friendly man-machine interface

The use of LCD liquid crystal display panel, Chinese and English display interface makes programming and parameter adjustment more convenient

  • Advanced communication function

Standard Modbus RTU communication. Optional Ethernet/GPRS communication module makes user’s network connection control easier and improves the system's automation level and reliability.

  • Unique SCR triggering close-loop control algorithm

The unique SCR close-loop control is specially designed for standard load and heavy load. User can choose current-limit start or voltage ramp start according to load conditions so as to realize absolutely smooth start without torque oscillation.

  • Dual parameter function

With two sets of basic parameters, it can control two motors with different power respectively.

  • Analog signal control

Users can input 4-20mA or 0-20mA standard signal, and conduct upper and lower limit setting of analog to achieve the start and stop control of motor and alarm.

The data (pressure, temperature, flow, etc.) can also be transmitted via a soft starter. It is provided with 4-20mA or 0-20mA standard analog signal output function.

  • Powerful anti-interference property

All external control signals are subject to optoelectronic isolation, and different anti-noise levels are set to adapt to the application in special industrial environments.

  • Self-adaption of power frequency

Self-adaption of power frequency 50/60 makes user easy to use.

  • Dynamic fault memory

Up to 10 failures can be recorded, making it easy to find the cause of the malfunction.

  • Movable panel

The panel can be moved to equipment operating surface through machine interface for remote control.

How to order

  • To place an order, please provide product model, specification, load and application condition to your supplier;

Special note: If client needs keyboard box to be externally placed, it is necessary to order the mounting accessoriess from manufacturer. When keyboard box is externally placed, it needs to lock the mounting fittings of external keyboard box onto door panel with its hole size of 115.5(H) * 104.2(W). For specific installation steps, please refer to our reference guide.


  • As the standard configuration of soft starter contains built-in current transformer, user does not need to externally connect the both.
