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.
Ec fan exchange air by moving the air in a variety of aquipment and systems, its superiority is not only reflected in the compact structure, low noise and high efficiency but moreover it can keep continuous speed adjustment based on real-time temperature or pressure change, furthermost saving the power
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. The basic interface: 0-10V/PWM, RS485/Modbus, 4-20Ma
5.The basic parameters of field programmable: Maximum speed, minimum speed, maximum power, maximum current, resonance avoid
6. Constant air pressure controlling function
7. Embedded design
8. Electro magnetic compatibility (EMC)
Air performance curves
Our performance curves are tested in test camber according to DIN 24163 and refer to an air density of 1.2kg/M3. Testing conducted with inlet cone in airflow direction A, without protection guard
FAQ
1 Can we buy a sample for testing?
Sure, you are welcomed to buy a sample before mass order.
2. 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.
