JKW series intelligent low voltage reactive power compensation measurement and control device

summarize

JKW intelligent low-voltage reactive power compensation measurement and control device is a new generation of products developed and produced by our company in order to meet the needs of the development of low-voltage reactive power compensation. The product adopts universal instrument size for easy installation and use. Man-machine contact uses LCD screen display and buttons, and has capacitor status indication. The control physical quantity is reactive power, and the switching oscillation of the capacitor is solved. The special computing chip is used to calculate the power parameters with high precision and high control precision, with over-voltage, under-voltage, over-temperature and other protection functions. When the power grid parameters exceed the set limits, the controller quickly cuts the capacitors that have been put in to protect the safe operation of the capacitors and extend their service life.

JKW is an integrated controller for reactive power compensation and distribution monitoring, which integrates multiple functions such as data acquisition, communication, reactive power compensation, power network parameter measurement and analysis. If this product uses RS485 communication mode, it can network up to 32 sets of the company's YLZN, YLZK series combined low-voltage power capacitor compensation device or YLFK series communication type composite switch.

Main feature
