EC Cooling Fan Overview AC to DC cooling fan data

EC fan is DC DC motor and speed control function, directly applied to the AC power input environment, the use of high efficiency and energy saving DC DC motor, power consumption compared to the general AC motor to reduce more than 80%, and our company according to customers IP56, IP68 and ATEX explosion protection protection design to protect the long-term use of products and security.

Ordinary cooling fan, it is estimated that we are familiar with it can be divided into AC fans, DC fans, EC fans which AC cooling fan is what we call the cooling fan, the principle of this fan and production methods are very simple, so we focus on Take the DC fan and EC fan.

DC fans and EC fans are DC cooling fan, but there is a certain difference between them, a simple summary: DC input is DC, EC can enter the AC, and AC into DC.

EC fan features: EC fan fan industry is a new species, it is different from other DC cooling fan, it can not only use the DC voltage power supply, but also can directly use AC voltage power supply. Voltage from DC 12v, 24 v, 48v, to AC 110V, 220V, 380V can be universal, do not need to add any inverter conversion. All internal components for the power supply DC power supply, built-in DC variable AC, the use of rotor position feedback, three-phase AC, permanent magnet, synchronous motor.

EC fan of the advantages: EC motor for the built-in intelligent control module DC brushless maintenance-free motor, comes with RS485 output interface, 0-10V sensor output interface, 4-20mA speed switch output interface, alarm device output interface and the main From the signal output interface, the product has a high intelligence, high energy efficiency, high efficiency, long life, low vibration, low noise and continuous uninterrupted work and so on.
