Waterproof Cooling Fan ’I can around the clock for you! ’

"Waterproof Cooling Fan" uses digital brush less DC external rotor motor centrifugal fan. Or, using a centrifugal fan EC motor. EC (Electrical Commutation) electrical power to DC power, built-in DC to AC (invert module through six), using the rotor position feedback, three-phase AC, permanent magnet synchronous motors. "h5雷竞技 " DC brush less motor is power quality and appearance rather than the substance of the motor, EC motor is essentially a three-phase AC permanent magnet synchronous motor) EC motor is a built-in intelligent control module DC brush less maintenance-free motor, comes with RS485 output interface, 0-10V sensor outputs, 4-20mA speed control switch output interface, output interface and main alarm signal output from the interface. "h5雷竞技 " with high intelligence, high energy, high efficiency, long life, low vibration, low noise, and other characteristics can work uninterrupted.
