EC Axial Fan, External Rotor 220V, Low Noise Energy Saving for Cabinet Cooling

1． 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,

2． 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,

3． Variable speed control of EC fan can be realized / achievedvia 0-10V speed adjustment and/or                

      external circuit impulse modulation

4． Constant torque ,constant speed and constant airflow of EC fan can be fulfilled via 180,sine                      

      SVPWM(Space Vector PWM)to meet customer needs

5． Intelligent EC fan can support users to realize centralized operation control by 485 bus and monitor as      

      many as 255 fans

6． EC fan has comprehensive protection function, such as phase failure, overvoltage, undervoltage,            

       locked-rotor, over current and temperature protection
