Functional features
1. Adopt AC sampling technology;
2.The fundamental wave power factor and the reactive powerof the fundamental wave are used as thecontrol physical quantity, with high control precision, no switching oscillation, and insensitive to harmonics;
3. Digital operation of control parameters, easy to use, one-step in place, no loss of power outage data;
4. Automatic optimization control scheme is adopted to reduce the frequency of switching and improve the service life of thesystem;
5. Strong anti-interference ability, able to resist the 2000V interference pulse directly inputfrom the power supply, without crashing orlosing data, stable and reliable operation;
6. Digital display of grid power factor, reactive power, voltage, current (primary side), control parameters;
7.It has two working modes: power factor mode and reactive power control mode to facilitateusers' installation and debugging8. lt can judge and display overvoltage and undervoltage and quickly cut off the
capacitor bank to prevent the capacitor bank from operating underovervoltage;
9. it is provided with optional swing and cut locking function (please specify when ordering goods);
10. It has the function of an optional delay time of 200 seconds from the cutting time to the putting time, so that the
discharge time is sufficient after the cutting time, and the power is reduced when the capacitor is put back into operationlmpact of the network (the user should specify when ordering);
11. The input resistance of the current sampling signal is less than 0.05 ohms, which can be taken out directly from the meteringloop;
12. The operation manual provides a large number of troubleshooting methods for convenient installation and debuggng.
