Intelligent Low-Voltage Integrated Filtering Power Capacitor

Introduction to the Integrated Filtering Power Capacitor

ZHIMING brand of ZMZ-X type intelligent integrated low-voltage filtering capacitor is designed for situations where the power grids have certain harmonic content, but the common type power capacitor fails to run normally.

The ZMZ-X type low-voltage intelligent integrated filtering capacitor is mainly applied to locations where the harmonic current is  40% below (such as frequency converter and other equipment), not only meets the requirements of reactive compensation and improving power factor, but also eliminates the influence of high-order harmonics on the system, improving the electricity quality.
