Product Details Company Profile

Description

Summary

JKW4 series of reactive power compensation in high-performance automatic controller of the single chip processor as the core, it pay in the series decompossition algorithm get all the power base wave daa, especially suitable for the power systemharmonic sources with the automatic control of reactive power compensation. All components USES bonding process, reflow soldering, and multichannel test procedure,to make each product has the same stability and reliability.

Features

-TO wave reactive power cutting calculation capacity, it can avoid capacitance any form of cutting and harmonic vibration, And in a harmonic occasions to correct the grid reactive power compensation.

-Power factor measurement precision, display a wide range.

-Real-display voltage distortion rate andcurrent distortion rate and voltage distortion rate exceeds protection function.

-Overvoltage and ower the voltage protection function.

-With Power-down data.protection features, the parameters will not lost after power-down

-Current signal input impedance less than 0.0Ω，and it can be used in tandem with other instruments

-Increased the current polarity can open identification function.Convenient wiring,it do not need to change current signal. it can set discharge delay time to make the remnants of the capacitor input,TO extend the service life of the capacitor, Most of the composite switch has re-enter the delay function,Choose to set the controller delay phenomenon,When this phenomenon will greatly affect the accuracy of compensation

-Through manual function of parameter setting,it is able to save the running state After power outage,and it will Continue to follow the call again after the power failure,The new manual mode of operation can choose any circuit when would be needed by manual poeration

-More Loop can be done,it could achieve 24 loop at the most ,In some cases,large capacity,loops are more need to use two controllers, and we only need one

-Change the value of the transformer trans former magnification setting,XXXX/1 transformer can also be used.
