"Micro Cooling Fan" is a new revolution in the fan industry, enabling AC and DC. DC voltage from 12v, 24 v, 48v, to exchange 110V, 380V can be generic, without adding any inverter converter. All internal components motor for the zero power DC power supply, built-in DC-AC (through six inverter module), using a rotor position feedback, three-phase AC, permanent magnet synchronous motors. (DC brushless motor is power quality and appearance rather than substance motors, "Micro Cooling Fan" is essentially a three-phase AC motor is a permanent magnet synchronous motors). Built-in intelligent control module is maintenance-free brushless DC motor, comes with RS485 output interface, 0-10V sensor outputs, 4-20mA speed switch output interface, the output alarm signal output from the interface and the main interface. "Micro Cooling Fan" with high intelligence, high energy, high efficiency, long life, low vibration, low noise, and other characteristics can work uninterrupted.
