Quick Brief

Place of Origin: Zhejiang China (Mainland) Brand Name: Wiscon Model Number: JKW5

Specifications and Product Details:

1.General Description

JKW5 controller adopts SCM with high performance as the basic hardware and special control program structure manufactured with ten-year experience. With the help of high-speed calculation and logic judgement of computer, the controller can realize the intelligence.

2.Features

(1)Adopt AC sampling technology

(2)Math integral, filter the wave, no sensitive to harmonic wave

(3)The reactive power as the control physical quantity,high control accuracy, without switching vibration.

(4)The control parameter is operated by math, it is convenient to operate, the data of power failure doesn't lose.

(5)Adopt the control scheme which can find the superior one automatically, reduce the switching times, improve the system service life.

(6)With strong anti-interference, it can resist the 20000V inference impulse inputted from the power supply, it can't lose the data until machine is dead, and it is available to run.

(7)The digits display the power factor of power net work, reactive power, voltage,current(primary side) and control parameter.

(8)It has manual running mode and automatic running mode,so it is convenient for customers installing and debugging.

(9)It indicates the over voltage and under voltage clearly,owns the obvious function of cutting capacitor bank rapidly.it prevents capacitor bank running under the over voltage.

(10)With optional locking function of switching vibration(it is stated when user orders).

(11)The single capacitor has the optional functions for delaying 200s from switching in to switching off,it has full discharging time after the capacitor bank being switched off,it can reduce the impact to power network from capacitor,(it is stated when user orders).

(12)When the input resistance of current sampling signal is less than 0.05Ω , it can be withdrawn from the measuring circuit.

(13)With the selection function of full automatic mode and manual setting mode.

(14)The product manual provides a lot of removing methods for faults,so user can install and debug.
