This document is the user manual for GZK870I intelligent reactive power compensation controller produced by Shenzhen Autel Electrical Appliance Co., Ltd. in 2008. The product has features such as automatic phase recognition, route selection, power-off memory, and undervoltage setting, and can be used for compensating reactive power in low-voltage distribution systems.
The Autel GZK870I is a dedicated controller for compensating reactive power in low-voltage distribution systems. It features automatic phase recognition, configurable output channels (4 to 12), and robust interference resistance. The device allows users to set parameters such as switching points, delay times, and protection thresholds via an operation panel. This manual is written in Chinese.
