Audited Supplier EC Fans introduction
EC(Electronically Commutation)Motors, as bulit-in DC inverter driver three-phase AC external rotor permanent magnet synchronous motors,its efficiency and low nose is considered to be the untimate fan energy technologies.
The basic functions and performances of EC fan controller
Sensorless permanent magnet motor drive;
Wide input voltage range, single-phase 110-270V, three-phase 250V-480V, 50/60Hz;
PC(Power factor correction): Passive and active(IEC61000-3-2);
Soft start, adjustable acceleration, CVT;
Design operating temperature range: -30 ~ 60 degrees of minimum selection (The device in accordance with -40~ 85 degrees);
Protection: Overvoltage, undervoltage, overtemperature, overcurrent, phase loss detection, communication failures...
