◆Product Features
▲ Automatic identification of sampling current polarity, LED digital display of grid power factor, voltage and current values;
▲ The front panel button operation can switch between automatic/manual mode, and manual switching can be achieved on this machine when set to manual mode;
▲ Overvoltage protection, undervoltage protection, low current cutoff, delay time, number of output channels, and upper and lower limits of power factor can all be set through front panel button operation. The FRAM ferroelectric memory is stored and the power-off state is not lost;
▲ Advanced fuzzy control technology, with the power factor set by the user as the target limit, the sampled physical quantity as the reactive current of the power grid, and overvoltage and undercurrent as the limiting conditions;
▲ Control circuit: 1-12 output circuits;
▲ Strong anti-interference ability, able to withstand interference pulses with an amplitude of 2000V directly input from the power grid, higher than national professional standards.
◆TECHNICAL INDEX
▲ Input signal: power supply voltage UA=220V ± 10%, input current series connected to the A-phase signal current transformer circuit of the main cabinet (with an internal 0.2 Ω resistor);
▲ Output capacity: Each contact has a capacity of AC380V/3A or AC220V/5A;
The overvoltage protection is set to 110% to 120% of the rated voltage value. Set at 253V (115%) when leaving the factory;
The undervoltage protection is set to 70% to 90% of the rated voltage value. Set at 176V (80%) when leaving the factory;
The low flow prohibition setting value is 1% to 25% (5A is 100%), and it is set at 2% when leaving the factory.
