The JKFG series controller, powered by an 8-bit microcontroller, utilizes a split-phase sampling and supplementation control scheme. It is specifically designed for reactive power compensation in AC 50Hz, 0.4kV three-phase load imbalance power systems.

• Dynamic digital display for three-phase voltage, current, active/reactive power, power factor, and grid frequency.
• Robust anti-interference: withstands pulses up to 2000V directly from the power supply.
• High control accuracy using reactive power as the primary control physical quantity.
• Customizable parameters with non-volatile memory during power failures.
• Automatic phase recognition function ensures sampling signal consistency.
• Safety protections: Over-voltage, under-voltage, and phase loss protection.
• Versatile compensation: split-phase, three-phase, or combined modes.
