General Description
JKW15 APFC Reactive Power Compensation Controller is a special equipment to compensate reactive power for low-voltage power distribution systems. T597 design. The sampling physical quantity is reactive power, and the switching signal output controls the AC contactor to switch the power capacitor. It has the advantages of beautiful appearance, novel design, multiple functions, good control performance, and high reliability. It is in a leading position among similar products in China and provides a new type of equipment for power distribution automation. This series of products will display 2yxX when power on, indicating the program version of the product.
Standard JB / T9663-2013.
Working conditions
鈼?Power supply voltage: The rated value is 380V AC, and the fluctuation must not exceed 20%;
鈼?Ambient temperature: -25 鈩?~ 55 鈩?
鈼?Relative humidity: the maximum relative humidity is 90% (at 20 掳 C);
鈼?Altitude: no more than 2000m;
鈼?Environmental conditions: no explosive and flammable dangerous media, no corrosive metal gas and conductive dust that damages electrical insulation.
The main technical parameters
鈼?Rated current: ACO ~ 5A;
鈼?Rated voltage: AC220V / 380V;
鈼?Contact capacity: AC220V / 7A or AC380V / 3A per branch;
鈼?Current input impedance: 鈮?.02Q;
鈼?Shell protection level: IP30;
鈼?Frequency: 50Hz;
鈼?Sensitivity: 50mA;
鈼?Insulation voltage: 690V.
Features
鈼?Real-time display of network conditions: including reactive power, power factor, secondary current, primary current, system voltage, etc. (switching by clicking the up and down keys during automatic operation);
鈼?Automatically identify the polarity of the sampling signal, and there is no concern about the polarity of the wiring;
鈼?It has the function of setting parameter memory after power failure, and data will not be lost after power failure;
鈼?With over-voltage and under-voltage protection;
鈼?Has a double input threshold: only when the power factor is lower than the input threshold set value and the reactive power is greater than the minimum set of capacitor set values, it can be switched on to effectively prevent switching oscillation;
鈼?The input and removal delays can be adjusted separately, which has more power grid applicable ability;
鈼?Capacitor capacity input function, automatic identification numbering method for optimized switching;
鈼?There is a re-locking time that can be set to ensure that the capacitor has sufficient discharge time before being put into operation;
鈼?The output signal can be set to close a certain group or start a certain group of work by parameter setting;
鈼?All parameters are fully digital adjustable, which can be widely applied to different grid conditions;
鈼?Strong anti-interference ability, it can directly resist the interference pulse from peripheral common mode amplitude 2000V.Customized Compensation Controller
