Product Description
Inspection of product nameplate: Confirm whether the cargo received by you is consistent with the product ordered by you.
Service conditions
Service conditions have a great influence on normal working and lifetime of the soft starter, thus the soft starter should be installed in the place with the following conditions met.
Service conditions of conventional product:
Power supply: Electric supply, self-provided power plant and diesel generating set.
Three-phase AC: 380V (-20%, +15%), 50Hz.
Applicable motor: General squirrel cage asynchronous motor (the wound-rotor motor can be negotiated).
Start frequency: The standard product is suggested to be started/stopped not more than 15 times an hour (based on load).
Cooling mode: The standard type is natural air cooling.
Protective grade: IP00.
Environmental conditions: The environment temperature is -25ºC~40ºC, and the humidity is ≤95% (20ºC±5ºC). There are indoor installation and good ventilation instead of condensation, flammable, explosive and corrosive gases and conductive dust. The vibration is less than 0.5G and the capacity should be lowered accordingly for use when the elevation exceeds 2,000 m.
Pursuant to actual rate current of the motor, rated output of soft starter should be reset at the time of use with reduced capacity to ensure accuracy of various control parameters and fault protection.

Protection level of thermal overload of motor
Typical applications:
Water pump: reduce the mechanical stress of the motor, reduce the starting current of the motor, and prevent the water hammer effect when stopped
Fan: Reduce belt wear and mechanical impact, save maintenance costs;
Compressor: use current limiting to achieve smooth starting, reduce motor heating, and prolong service life;
Crusher: Use locked-rotor protection and quick protection to avoid mechanical failure or blockage caused by motor overheating and burnout.
Transfer Machinery: Soft start for a smooth and gradual starting process to avoid product displacement.
Function:
Lower starting current of the motor, reduce the power distribution capacity and avoid capacity-increase investment;
Reduce the starting stress and prolong the service life of the motor and related parts;
Various starting modes, setting of wide range of current, voltage and time and adapting to start/stop of the motor based on a variety of loads.
Our soft starter is cored on advanced dual-CPU control technology. It controls controllable thyristor module, realizes soft starting & stopping of three-phase AC induction motor, and has wide range of protection functions e.g. overload, input phase failure, output phase failure, load short-circuit, starting limiting overtime, over-voltage, and undervoltage.
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. |
