China Wholesale 3 Phase Power Factor Controller Manufacturers - JKW series reactive power automatic compensation controller – LASTONE Detail:

Overview

JKW series reactive power automatic compensation controller is suitable for the automatic adjustment of capacitor compensation device of low voltage power distribution system (hereinafter referred to as the controller), so that the power factor can reach the user’s predetermined state, improve the utilization efficiency of power transformers, reduce line losses and improve voltage quality of power supply , thereby improving economic and social benefits.

Standard： JB/T 9663-2013

Features

● Calculate switching capacitor capacity with reactive power, high compensation accuracy

● Power factor measurement has high accuracy and wide display range.

● Initial phase preset (software adjusts the same terminal or current signal polarity)

● Two control modes: power factor and reactive power, HMI is easy to operate

● Various control parameters are fully digital adjustable and intuitive to use

● With two working modes: automatic operation and manual operation

● With over-voltage and under-voltage protection

● With data storage protection when power off

● The input impedance of the current signal is ≤ 0.01Ω.
