YJ-JQK Intelligent Reactive Power Compensation Controller

Application
Designed for controlling YJ-BSIC series intelligent capacitors' switching.
Displays grid parameters and capacitor operation status.

Product Features:
Control Function:
(1) Supports automatic/manual/debugging operation modes.
(2) Adopts a multi-parameter composite control strategy. Controls capacitors with equal capacity in the system by switching in a cyclical manner based on the desired reactive power.

Measurement Function:
Capable of measuring grid voltage, current, active power, reactive power, power factor, and automatically detecting CT direction.

Protection Function:
Equipped with overvoltage protection, undervoltage protection, overcurrent protection, phase loss protection, harmonic protection, and overtemperature protection.

Human-Machine Interface:
(1) Displays basic grid parameters.
(2) Allows for setting capacitor capacity, address coding, switching threshold, switching delay, transformer turns ratio, and other parameters.
(3) Can be optionally configured with a 485 communication interface for backend management, telemetry, and remote control.
(4) Models ending with -G2 or -H2 also feature a status display function, showing capacitor operation status.
