220v Small Double Inlets Forward Centrifugal Blower Fan HVAC Air Cooing High Pressure

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. Sensorless permanent magnet motor drive

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