什么是EC風機呢？

經(jīng)常碰到客戶詢問，簡單介紹如下：
1. EC技術(shù)風機，可通過外部的電路脈沖調(diào)制或0-10V的電壓調(diào)節(jié)來實現(xiàn)風機的無級變速。

Variable speed control of EC fan can be realized/achievedvia 0-10V speed adjustment

and/or external circuit impulse modulation.

    2. EC技術(shù)的風機通過180度正弦（SVPWM）矢量控制可實現(xiàn)智能的恒轉(zhuǎn)速、恒轉(zhuǎn)矩、恒流量控制，滿足客戶的智能需求。

Constant torque,constant speed and constant airfiow of EC fan be fulfilled via180° sine SVPWM(Space Vector PWM) to meet customer needs.

   3. 智能的EC風機可支持用戶通過485總線實現(xiàn)集中運行控制和監(jiān)控多達255臺風機。

Intelligent EC fan can support users to realize centralized operation control by 485 bus and monitor as many as 255 fans

   4. 采用EC 技術(shù)的風機擁有全面的保護功能：如缺相、浪涌電壓、過欠電壓、堵轉(zhuǎn)、過電流、溫度保護等。

EC fan has comprehensive protection function,such as phase failure,overvoltage, undervoltage,loched-rotor,over current and temperture protection.
