模块特点  Module Characteristics

1. 交流输入范围宽：260～500VAC

   Wide range of input AC: 260～500VAC

2. 先进的三相有源PFC技术: 更好地抑制高次谐波，THD满载时小于5%，功率因数可达0.99。

 Advanced PFC technique: high-frequency harmonic can be restricted better, and power factor can be 0.99

3. 智能温控风冷方式：增加风机的使用寿命,使模块运行更可靠，噪音更小。

       Intelligent temperature-controlled wind cooling: the usage life of fan is prolonged, which              makes module running more safely.

4. 先进的LLC谐振变换器技术：工作频率高，开关损耗小，转换效率高，大大减小磁性元器件体积，使模块体积和重量大幅减小。

       Advanced LLC resonant converter technology: high frequency, low switching loss, high efficiency, greatly reduce the size of magnetic components, the module size and weight significantly reduced.

5. 先进的数字控制方式：摒弃了以前所用的模拟控制方式，改用数字控制方式。模块精度更高，响应速度更快，校验和升级也更加方便。

Advanced digital control: to abandon the method ,which used analog-control previously, and use digital-control. Module has higher accuracy, faster response. Calibration and upgrade are more convenient.

6. 模块支持热插拔，使日常维护和维修方便快捷。

   Module supports hot-swap, so that routine maintenance and repair quickly and easily.

7. 独立工作能力：模块在脱离监控的情况下，可以正常工作。

   Ability to work independently: if the module brakes away from the monitor , it can work normally.
