Durable Cooling Fan With Zw450c-230d3-00 For Eshaust Ventilation

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． Enable the selection of different power levels thus to get the best match of price and performance             according to customers’load requirements

4． As the rotor is mounted to interior, the external rotor fan is more compact constructed, smaller and            easy to abstract heat., thus ensure to maximum the reliability of fan operation,

5． Sustainable speed control benefits to achieve low operating costs, reduce CO2 emissions protect the       environment, enable the direct, simple communication between the host controller and the system,

6． Variable speed control of EC fan can be realized / achievedvia 0-10V speed adjustment and/or                  external circuit impulse modulation
