Product Overview

The JL2000 series LCD intelligent compensation controller is a new type of power distribution measurement and control device that integrates data acquisition, reactive power compensation, and grid parameter analysis. It is suitable for monitoring and reactive power compensation control in 0.4 kV, 50 Hz AC low-voltage power distribution systems.

Performance Features

①　Capacitor switching capacity is calculated based on fundamental reactive power, preventing various forms of switching oscillation. It offers strong resistance to harmonic interference, accurately displays the grid power factor in the presence of harmonics, ensures reliable switching control, and includes harmonic protection functions.

②　The capacitor capacity controlled by each output signal can be set arbitrarily, without requiring specific coding; features real-time monitoring of electrical energy data:

③　Voltage, current, and power factor for phases A, B, and C

④　Switching status of capacitor banks for phases A, B, and C

⑤　Active power and reactive power for phases A, B, and C

⑥　Total Harmonic Distortion (THD) for voltage and current, and system frequency for phases A, B, and C

⑦　Harmonic content rates for voltage (3rd, 5th, 7th, 9th, 11th, and 13th harmonics) for phases A, B, and C

⑧　Harmonic content rates for current (3rd, 5th, 7th, 9th, 11th, and 13th harmonics) for phases A, B, and C

⑨　Response time from detection to switching can be as fast as 20 ms, enabling rapid switching; features a user-friendly human-machine interface.

⑩　Wide adjustment range for target power factor.

⑪　Includes over-voltage and under-voltage protection functions.

⑫　Includes power-loss protection (data retention) and communication capabilities.

⑬　Features harmonic detection and robust protection against harmonic interference.
