JKW-2 series of intelligent reactive power compensation controller using the most advanced single at home and abroad

Chip control technology, sampling the physical quantity of reactive power, AC sampling high-power grid

Harmonic interference, extraction of fundamental power parameters control the power capacitor connected to improve work

Rate factor, the series of products meet the JB / T9663-1999 industry standards, can be widely applicable

Should be in different grid conditions.

● Power supply voltage: 220V or 380V AC rated, the fluctuation can not exceed ± 10%.

● Ambient temperature: -25 ℃ ~ 55 ℃.

● Relative humidity: maximum relative humidity of 90% (20 hours)

● Altitude: not more than 2000m.

● environmental conditions: no explosive flammable hazardous media, non-corrosive metal gases and damage to electricity

Gas-insulated conductive dust.

● Real-time display of three-phase network status: including system voltage, system current, power factor and

Control parameters;

● automatic identification of sampling signal polarity, wiring polarity of the wrong polarity of the worry;

● Power-down memory with set parameters, data is not lost after power-down;

● with over-voltage and under-voltage protection;

● With low reactive blocking function, the reactive power is higher than the C / K set value and the power factor is low

The input threshold set back before the investment, effectively prevent switching oscillation;

● use of the cycle of switching work, and switching delay adjustable;

● All parameters are all digital adjustable, intuitive and simple, can be widely applied to different power grid conditions;

● Anti-interference ability, can directly resist the interference from the foreign common mode amplitude 2000V pulse.

1.1 Basic technical parameters
