Function and Application
The JKF8 series intelligent low-voltage reactive power automatic compensation controller (referred to as the controller) is used in conjunction with low-voltage parallel capacitor screen devices, suitable for distribution systems with a rated voltage of 380V, AC, 50Hz. It controls the automatic connection and disconnection of parallel capacitors, improves voltage quality, and reduces energy loss. This product has passed the type test by the Power Industry Reactive Compensation Assembled Device Quality Inspection and Testing Center, and its main performance indicators have reached domestic advanced levels. It has a fully automatic mode, a 'dumb' design, and is one of the most cost-effective reactive compensation controllers in China at present.
