什么是EC風機呢？

經常碰到客戶詢問，簡單介紹如下：
1. EC技術風機，可通過外部的電路脈沖調制或0-10V的電壓調節來實現風機的無級變速。

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

and/or external circuit impulse modulation.

    2. EC技術的風機通過180度正弦（SVPWM）矢量控制可實現智能的恒轉速、恒轉矩、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總線實現集中運行控制和監控多達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、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.
