What is EC technology?
EC Technology stands for Electronically Commutated and combines AC and DC voltages, which is essentially a fan with a brushless DC motor, bringing the best of both technologies: the motor runs on a DC voltage, but with a normal AC supply. DC motors already have low power consumption but if used in an AC application, the power needed converting AC to DC, using a bulky, inefficient transformer. The EC motor incorporates voltage transformation within the motor. The non-rotating part of the motor (stator) is extended to make room for an electronic PCB board which includes power transformation AC to DC, as well as the controls.

 

Advantages of EC technology

Very high degree of efficiency

Integrated controller (continuous control)

Very simple connection

Additional functions (pressure control, airflow, speed, temperature, air quality, etc.)

Smaller-sized motor for the same level of performance

Less power consumption

 

 

The basic functions and performances of EC fan controller

1. Sensorless permanent magnet motor drive

2. Wide input voltage range, single phase 110-270V, three phase 250v-480v, 50/60hz

3. Power factor correction(PFC): Passive and active(IEC61000-3-2)

4. Soft start, adjustable acceleration, CVT

5. Design operating temperature range: -30~60 degrees of minimum selection(The device in accordance with -40~85 degrees)

6. Protection: over voltage, over temperature, over current, phase loss detection, communication failures.

7. The basic interface: 0-10V/PWM, RS485/Modbus, 4-20Ma

8.The basic parameters of field programmable: Maximum speed, minimum speed, maximum power, maximum current,

resonance avoid

9. Constant air pressure controlling function

10. Embedded design

11. Electro magnetic compatibility (EMC)

FAQ

1. How do I know which model I should choose

Please tell us the fans pressure and ofan and size of fans’ diameter you need. We will study and suggest you the right model.

2. Can we buy a sample for testing?

Sure, you are welcomed to buy a sample before mass order.

3. if the fans doesn't work well, what shall I do ?

If happens within one year, we will take in charge of the maintenance, or send you a new machine freely.
If after one year, we will supply you the right parts to replace at low price.
