JKW Series reactive power compensator

○ Adopt AC sampling technology

○ Digital integration,filtation,not sensitive to the harmony mave.

○ regard the teactive power as controlling physical quantiry ;it has high control precision without input and cut off shaking.

○ The operation of the full digital of control patameter ,easy to use, put in right place in one step .and the date are not lose to have a power failure.

○ Adopt and optimize the excellent control scheme automatically ,reduce the times of input and cutoff , impove the setvice life of system.

○ Strong anti-interference ability can resist 2000V interference pulse from power direct,and not crashing ,does not lose the data ,it is reliable to run steady.

○ Digital display electric network power factors ,reactive power, voltage ,current(primary side)and control parameter.

○ With two working modes of manual and automatic is convenient for user to install and debug.

○ With the function of over-voltage judgent and display and fast cutoff capacitor group,prevent capacitor group from running under the over-voltage condition.

○ With the function of available input and cutoff shocking and locking(the used must specity when ordering).

○ With the function for the delay time of the selectable single group capacitor for 200 seconds from cutoff to input, makes capacitor have abundant discharging time after cutoff and reduce capacitor the impact in electric net when putting into again(The user must specify when ordering)

used must specity when ordering).

○ The input resistance of current sampling signal is smaller than 0.05Ω；it can be taken out from measuring loops directly.

○ Output loops 1-12LOOP
