| General Description | This series of devices regardhigh-performance single-chip micro
computers the basic hardware, adoptAC sampling, digital
integration, filtration technology, can trace andcompensate the
reactive electricity intelligently. This method hasprevented the
problem caused when contactor input and cut off thecapacitor,
through compounding switch (input and cutoff mode ofcombining with
crystal braking-tube and contactor ) and input and
cutoffover-zero,so as to prevent the〃surge current〃 caused while
capacitorinputting. Three is no mechanical movement,and electric
arc. No harmonicwave fast compensating speed that is especially
suitable for using atthe place of frequent inputting and cutting.
And this method can lenghenthe service life of the main device of
capacitor. It has reason-ablestructure, modern techniques, mainly
apples to the low-voltage powernetwork to increase power factor
and reduce reactive loss, improve power supply quality. It is the
newgeneration economizing on electricity products and also is one
of theadvanced compensator both at domesticand inter-national at
present. |

| Main Characteristics | Small volume, convenient for installing and maintenace,good water
proofperformance, and can be used for both outdoor and indoor.
Controlling parameter full digital operation, convenient for using,
the
data cannot lose when power off.
Digital display power network power factor, reactive power,voltage,
current (one side), control parameter.
With the function of over-voltage, under-voltage judgment displays
and fast cut off the compensated capacitor group.
With two working modes of manual and autocompensation.
It has the function of auto selecting the best mode to input and
cutoff
compens ation according to the result of capacitor group manual
input.
With two working modes of cycle or optimizing input and cutoff,
thecompen-sation Includes controlling mode of
1:1:1:11:2:2:21:2:4:8thecompensator will automatically distinguish
its code working mode ofmanual input duplexure capacitance value,it
works according to thecorrespondence code mode.
With two working modes of power factor or reactive power;
Compensating mode:①Phase splitting compensation ②Phase splitting
and three-phase compensation ③Three-phase compensation.
Control modeCrystal braking-tube input and cutoff ②Compound
