JKW reactive power controller

high-performance single-chip micro computer as the basic hardware, fully utilize high-speed operated strength

JKW series reactive power auto compensating controller is suitable for self-adjusting

capacitor compensation devices in low voltage distribution increase the efficiency of the power

transformer, reduce line loss, and improve voltage quality. On final aim it will increase the economic and social benefits.

Function characteristic

Adopt  AC sampling technology

Digital integration, filtration, not sensitive to the harmony wave.

Regard the reactive power as controlling physical quantity;  it has high control precision, without input and cutoff shaking.

The operation of the full digital of control parameter, easy to use, put in right place in one step, and the data are not lost to have a power failure. Adopt and optimize the excellent control scheme automatically, reduce the times of input and

cutoff, improve the service 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, under-voltage judgment 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(please indicate while or

during goods).

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 (Please indicate while ordering goods).

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

Output Loops 1-12 Loop
