ECM fan controller of 180 ° Sine wave DC inverter controller (permanent wind control)
1, 180 ° Sine wave DC inverter technology 2, 180 ° Sine wave-driven is more stable and quieter than the 120 ° Square wave. 3, With no location sensor, safer and more reliable. 4, Adjusting the speed within the super wide range of 100 rpm ~ 1500rpm, getting milder wind, and saving more power for the overall machine. 5. Torque mode, permanent wind control, and large wind outlet amount. 6, intelligent protection system, safer, and more stable H2: Power source panel of 180 ° Sine wave DC inverter ECM fan |
