Product Introduction

EC Backward centrifugal fan 280mm

Features of EC fan: EC fan is a new type of fan industry. It is different from other DC cooling fans. It can not only use DC voltage for power supply, but also use AC voltage for power supply. The voltage can be universal from DC 12V, 24V, 48V to AC 110V, 220V, 380V, without adding any inverter conversion. All internal component motors are DC power supply, built-in DC to AC, rotor position feedback, three-phase AC, permanent magnet and synchronous motors.

Application

EC fans have been widely used in: communication equipment, UPS power supply, medical equipment, electric welding machine, industrial control equipment, household appliances.

Advantages of EC fan: EC motor is a DC brushless maintenance-free motor with built-in intelligent control module. It is equipped with RS485 output interface, 0-10V sensor output interface, 4-20mA speed control switch output interface, alarm device output interface and master-slave signal output interface. This product has the characteristics of high intelligence, high energy saving, high efficiency, long service life, small vibration, low noise and continuous and uninterrupted operation.

Traditional DC motor has a shell, which contains all components, such as carbon brush, commutator, bearing, armature with winding, etc. They are arranged one by one. The use of EC motor components saves more space and eliminates the need for collectors and carbon brushes. Therefore, the motor is significantly shorter, so it has advantages in size and quiet operation during installation.
