Type B of the main control panel of 180°DC frequency-converting ECM fan of sine wave

•180°DC frequency-converting technique of sine wave

•180°drive of sine save is more stable and quieter than 120°square wave.

•With no location sensor,safer and more reliable

•Adjusting the speed within the super wide range of 100rpm~2000rpm,getting milder wind,and saving more power for the overall machine.

•Torque mode,permanent wind control,large wind outlet amount
