JL-ZMJ Smart Filter Capacitor Unit
This product is mainly used for reactive power compensation in environments with severe harmonics. It operates reliably without triggering resonance or amplifying harmonics, and can absorb and eliminate harmonics to a certain extent.
Project Overview
This product is mainly used for reactive power compensation in environments with severe harmonics. It operates reliably without triggering resonance or amplifying harmonics, and can absorb and eliminate harmonics to a certain extent. Models equipped with 7% series reactors are suitable for working conditions dominated by the 5th harmonic, while versions fitted with 14% series reactors apply to environments where the 3rd harmonic prevails.
Product Features
The JL-ZMJ series intelligent filter capacitor adopts a modular floor-mounted structure, featuring compact size, flexible combination, easy wiring and maintenance. System capacity expansion can be achieved simply by adding modules. Supported by intelligent zero-crossing switching relays, it realizes switch-on at zero voltage and switch-off at zero current. No inrush current, switching overvoltage or arcing occurs during operation, reducing system power consumption.
