Common cooling fans are EC, DC, AC, etc. EC fan is DC fan, which is AC to DC fan. It can not only use DC voltage power supply, but also AC voltage power supply. The voltage of 12V, 24V, 48V, 110V, 220V, 380V can be universal, without conversion.

Advantages of EC fan:

1. EC fan breaks through the frequency limit of the traditional AC fan, which can greatly improve the fan speed, lightweight motor design and reduce the air area.

2. EC fan motor built-in intelligent control module, DC brushless maintenance free type, with high efficiency, high energy saving, long life, low vibration, low noise, continuous work and other advantages.

3. The simplified structure not only improves the technological performance of the motor, but also enhances the mechanical reliability of the motor, increases the service life, greatly improves the air gap flux density, achieves the best design, reduces the volume and weight of the motor.

4. EC fan can do a variety of speed control and other functions, such as PWM, TC, VC temperature control, lower energy saving, can do a variety of signal output, real-time monitoring of fan running state.

5. EC fan can do high power, with soft start function, small starting current, less impact on power grid and equipment, higher reliability.

Dongxingyue specializes in cooling fans, including DC fan, AC fan, DC blower, centrifugal fan, EC centrifugal fan, cross flow fan, etc., which are mainly used in home appliances, communication, medical equipment, automobile, LED lighting and other industries.
