JKW-2 Three phase common compensation intelligent reactive power compensation controller

Main purpose and scope of application
JKW-2 series intelligent reactive power compensation controller adopts the most advanced single-chip control technology at home and abroad, the sampling physical quantity is reactive power, AC sampling resists the interference of high-order harmonics of the grid, and extracts the fundamental power parameters to control the power The capacitor is connected to improve the power factor, which can be widely adapted to different power grid conditions.
This product complies with: industry standard JB/T9663-2013 (our company is the main drafting unit of this standard).

Model and meaning

Working conditions
1. Power supply voltage: the rated value is AC 220V or 380V, and the fluctuation cannot exceed ±20%;
2. Ambient temperature: -25℃~55℃;
3. Relative humidity: the maximum relative humidity is 90% (at 20℃) ;
4, altitude: not more than 2000m;
. 5, environmental conditions: no explosion hazard medium flammable, non-corrosive metal gas and damage of an electrically insulating conductive dust;

Features
1. Real-time display of three-phase network status: including system voltage, system current, power factor and control parameters, etc.;
2. Automatically identify the polarity of the sampling signal, and there is no concern about the polarity of the wiring;
3. With memory for setting parameters, power-off Function, data will not be lost after power failure;
4. With over-voltage and under-voltage protection function;
5. With low reactive power blocking function, the grid reactive power is higher than the C/K setting value and the power factor is lower than the input threshold setting value It can effectively prevent switching oscillations;
6. It adopts cyclic switching mode, and the switching delay is adjustable;
7. Various parameters are all digitally adjustable, intuitive and simple, and can be widely applied to different power grid conditions;
8. Strong anti-interference ability, can directly resist interference pulses from peripheral common mode amplitude 2000V;
