Baoding Hongri Electric Co., Ltd.

Application:For 5.5-300kW D.C. motor, applied in high frequency welding pipe、metallurgy、plastic、paper-making、cement etc. industries.
Application Environment Request：
1、Indoor installation
2、The altitude cannot exceed 2000m
3、No corrosive and gas destroying electric isolation.
4、Environment temperature is between -10℃ and 40℃, air relative humidity cannot exceed 85%.
5、No electric dust、no severe shake and impactive situation
6、Installing gradient is not beyond 5°
Main advantages：
1、Microcomputer control board adopts MCS-51,the number of control boards is decreased to one from several boards.
2、Main circuit applies three-phase full controlled bridge structure, thyristors are cooled down by water or wind.
3、Primary transformer is dry type.
4、The LED displays all running state.
5、Structure is reasonable, convenient to use and maintain, the noise is low.
Technical guide line:：
Input voltage：three-phase four-wire system 380V±10%
