Working principal:

CPU controls the SCR to conduct phase angle trigger control, lowering the voltage on motor, then controls the voltage on motor and increases the motor torque of the smooth current until motor runs in full speed. The above way of starting can lower the inrush current of motor, reducing the impact on power grid and motor itself. Meanwhile, it also reduces the mechanical impacts on motor loading device, prolonging device service life and reducing motor breakdown.

Protection level of thermal overload of motor
The thermal overload protection of electric motor is reverse time limit overload protection. It is used to protect the motor by estimating the internal heat generated by the motor in the process of starting or running with a scientific calculation method. The mathematical model is established referring to IEC60947-4-2 standard, JB/T 10613-2006 standard and the performance characteristics of AC asynchronous motor in China. The overload protection curve of the starting power motor is drawn in the coordinate system according to this mathematical model, which is divided into 20 protection levels, as shown in the figure below. Level 1~8 is used in the thermal
overload protection of motor operation and the factory default value is 3; Level 9~16 is used in the thermal overload protection of motor start and the factory default value is 0 (close protection; no matter what kind of start mode, there is already protection on startup time); Level 17~20 is standby. When the thermal overload of motor does not reach the protection threshold at the start and operation process, and the working current recovers to the rated current, the heat integral constant can be restored to its initial state within 3 minutes. If the thermal overload of the motor exceeds the protection threshold, the soft start enters the protection state.

Installation Instructions


Installation of HV soft starter
4.1 Precautions for installation
on the base of the trench;
The reasonable installation can ensure the normal operation and service life of the equipment under the
conditions as follows:
4.1.1 Avoid installation in places with corrosive gases and metal dust;
4.1.2 Avoid installation in direct sunlight;
4.1.3 Take measures to prevent liquid from entering the inside of the device;
4.1.4 To obtain desirable ventilation and heat dissipation conditions, HV soft starter should be installed vertically
There is enough space for heat dissipation around the HV soft starter. The front and rear doors of the cabinet
can be opened for maintenance; keep the rear door of the cabinet and the wall at a fixed distance.

Our Advantages


The CGR series digital AC motor soft starter is a new type of starting device designed with power electronics technology, microprocessor technology, and modern control theory, which has reached the international advanced level. This product can effectively limit the starting current of asynchronous motors and can be widely used in loads such as fans, water pumps, conveyors, and compressors. It is an ideal replacement for traditional reduced voltage starting devices such as star/delta conversion, autotransformer voltage reduction, and magnetic control voltage reduction.

Our CGR  series soft starter has significant advantages in comparison to similar products.

Starting mode based on a variety of loads is used There are rich and diverse ways to start and convenient parameter settings, enabling the motor to achieve the best start effect based on different loads.
High technical performance Because the high-performance microprocessor and powerful software support functions are used, the control circuit is fully simplified and optimized and consistent and accurate operating performance can be realized without adjustment of circuit parameters.
High reliability All electrical elements are strictly screened and the control part of the whole machine is subject to high temperature cyclic test and vibration test which ensures high reliability of outgoing product.
Optimized structure Unique module structure and mode of connection entering at top and leaving at bottom are adopted, the anti-jamming technique is introduced, rational layout of control panel is conducted and the keyboard is of I2C bus with small volume. The optimized structure can facilitate integration and forming a complete set.  
Friendly human-computer interaction interface The display content of the keyboard is rich, the operation is intuitive and convenient as well as start, stop, operation and protection parameters can be set and modified according to different loads with real-time display of various working states. The interface can facilitate inquiry of operating current based on each phase and temperature and power frequency of the machine.
Impeccable motor protection function Online operation ability exists, real-time monitoring of working voltage, current and temperature can be realized, perfect comprehensive protection function of the motor is provided and the moderate protection threshold can be controlled to ensure the motor works stably furthest.
Rated output current can be reset When the nominal power of the soft starter exceeds actual load power, actual output current of the soft starter can be modified within a certain range to make it match with actual load to ensure accuracy of starting effect and protective function of the motor by the soft starter.
Excellent soft parking performance After you set the work mode, the effect of soft parking arises regardless of being in the start process or under the operation status. As for different kinds of loads, smooth stopping effect, especially the load of filling line and water pump applying to the line production can be achieved by reasonable parameter setting.
Industrial field bus is supported 485 communication function is provided and Modbus communication protocol based on international standard is supported.
