The difference between AC/DC/EC fans
Speaking of cooling fans, it is estimated that everyone is very familiar with it. We can not live without it, household appliances, electronic products, digital computers and so on. As long as we need to use it for cooling and exhaust, cooling fans can be divided into AC fans, DC fans and EC fans. Here, Denoson will explain AC/DC fans for you. The difference between /EC fans is:
AC fans are what we call AC heat dissipation fans. The principle and fabrication method of these fans are very simple, so we will not talk about them here in detail. Today we mainly focus on DC fans and EC fans.
DC fans and EC fans belong to DC cooling fans, but there are some differences between them. Simple summary: DC input is DC, EC can input AC, which converts AC into DC.
EC fan features: EC fan is a new type of fan industry, it is different from other DC cooling fan, it can not only use DC voltage power supply, but also can use AC voltage power supply. Voltages from 12v, 24v, 48V DC to 110V, 220V, 380V AC can be used universally without adding any inverters. All internal components of the motor are DC power supply, built-in DC converter AC, rotor position feedback, three-phase AC, permanent magnet, synchronous motor.
Advantages of EC fan: EC motor is DC brushless maintenance-free motor with built-in intelligent control module. It has RS485 output interface, 0-10V sensor output interface, 4-20mA speed regulating switch output interface, alarm device output interface and master-slave signal output interface. The product has high intelligence, high energy saving, high efficiency, long service life, etc. Small vibration, low noise and continuous and continuous work.
