When it comes to the cooling fan, estimates that everyone is very familiar with, deficiency in our life without it, home appliances, electronic products, digital computer, and so on, as long as the need to heat exhaust will use it, the cooling fan can be divided into AC fans, DC fans, EC fan, let small make up for you here about the AC/DC/EC fan is the difference between:
AC fan is what we call AC cooling fan, this kind of fan principle and production method are very simple, so here we do not talk about the details, today we mainly focus on DC fan and EC fan.
DC fans and EC fans are DC cooling fans, but there are certain differences between them. In a nutshell, DC inputs DC power, while EC inputs AC power, which converts AC power into DC.
Features of the EC fan: The EC fan is a new product in the fan industry. Different from other DC cooling fans, the EC fan can supply power not only with DC voltage but also with AC voltage. Voltage from dc 12v, 24 v,48v, to ac 110V, 220V,380V can be universal, no need to add any inverter conversion. All internal motors are dc power supply, built-in DC variable AC, rotor position feedback, three-phase AC, permanent magnet, synchronous motor.
Advantages of the EC fan: The EC motor is a brushless DC maintenance-free motor with built-in intelligent control module, equipped with RS485 output port, 0-10V sensor output port, 4-20mA speed switch output port, alarm device output port, and master/slave signal output port. The product has the characteristics of high intelligence, high energy saving, high efficiency, long life, low vibration, low noise and continuous uninterrupted work.
