The difference between AC/DC/EC cooling fan
Speaking of radiator cooling fan, estimates that everyone is very familiar with, deficiency in our life without it, home appliances, electronic products, digital car and so on, as long as the need to heat the exhaust is used it, radiator cooling fan can be divided into AC cooling fan, DC cooling fan, EC cooling fan, here by possessing DC cooling fan manufacturers' Chi automotive air conditioning 】 For everybody about the AC/DC/EC cooling fan: the difference between AC cooling fan is what we call AC cooling cooling fan, this kind of cooling fan principle and producing method is very simple, so here is not more auspicious fine about everyone, today we explain mainly focused on the DC cooling fan and EC cooling fan. DC cooling fan and EC cooling fan is belong to the heat dissipation DC cooling fan, but they, and certain difference between simple summary: DC input DC, EC can input alternating current (ac), it is to put the ac to DC. EC cooling fan features: new varieties of EC cooling fan is the cooling fan industry, it is different from other heat dc cooling fan, it not only can use dc voltage power supply, but also can use ac voltage power supply. Voltage from the dc 12 v, 24 v, 48 v, the ac 110 v, 220 v, 380 v can be general, don't need to add any inverter transformation. All internal parts for motor power dc power supply, built-in dc variable exchange, using rotor position feedback, three-phase ac, permanent magnet synchronous motor. Advantages of EC cooling fan: EC of brushless dc motor for the built-in intelligent control module type WeiHuXing motor, output with RS485 interface, 0 , 4-10 v sensor output interface 20 ma speed switch output interface, alarm output interface and master-slave signal output interface, the product has high intelligence, high energy saving, high efficiency, long life, small vibration, low noise, and can work continuously uninterrupted, etc. Above is the AC/DC/EC distinction between the cooling fan. Hope to be of help, wen ling chi auto air conditioning manufacturing co. , LTD is a professional research and development radiator cooling fan, radiator cooling fan, dc cooling fan, dc fan cooling fan peng brand manufacturers. Has a high-quality research and development of management and technical team, dc cooling fan, complete product specifications, quality excellent, free proofing, directly or indirectly from two days out of the sample, dc cooling fan price consultation: 18923728252
