1． EC fans includes AC input driven brushless DC fan with integrated design of AC-DC transformation circuit, the PFC circuit, the BLDC drive circuit, interface circuit. Due to the internal integration of the AC-DC converter circuit, the consumption of power will be reduced to facilitate the design and application of the overall power system in customer.
2． Brushless DC external rotor motor belongs to non-mechanical brush(commutator)DC motor which enforces the winding current commutation through electronic commutator (position sensing, non-position sensing),achieve the speed control function with PAM or PWM control
3.Design operating temperature range: -30~60 degrees of minimum selection(The device in accordance with -40~85 degrees)
4. Protection: over voltage, over temperature, over current, phase
loss detection, communication failures.
5. The basic interface: 0-10V/PWM, RS485/Modbus, 4-20Ma
6.The basic parameters of field programmable: Maximum speed,
minimum speed, maximum power, maximum current, resonance avoid
