YD-9CK-100 LCD Intelligent Capacitor Controller
YD-9CK-100 low-voltage reactive power compensation controller (controller for short), a new generation developed by our company, is based on various technologies of reactive power automatic compensation controller at home and abroad. With attractive design, it has full functions and full LCD menu. It’s flexible to install and apply the controller, and also it’s easy to operate it.
The controller uses RS-485 communication to connect with the intelligent integrated power capacitor produced by the company, with high integration degree, beautiful appearance, and universal instrument size. The controller has convenient installation and extremely simple wiring. Thus, the production efficiency and overall product quality are improved.
