Description

Product overview

The Voltage Sag Mitigation Solution for Sensitive Industries is a specialized device designed to protect sensitive loads from power quality disturbances, particularly voltage sags.

In simple terms, when sensitive equipment is connected to the AC power grid, disturbances such as voltage dips, sudden fluctuations, or harmonic distortions can significantly affect performance, stability, and even cause operational interruptions.

To minimize these impacts, a Dynamic Voltage Restorer (DVR) is connected in series with the three-phase circuit. During grid faults or disturbances, the DVR injects compensating voltage into the load side, ensuring stable and reliable voltage supply to sensitive equipment.

This solution is particularly critical in industries where high reliability and stability are essential, such as:

Semiconductor and electronics manufacturing
Pharmaceutical and biotechnology plants
Precision equipment and data centers
Petrochemical and chemical processing facilities

By mitigating voltage sags and harmonics, the system ensures consistent power quality, protecting sensitive industrial processes and reducing production downtime.

Main Features

High reliability: Purpose-designed for industrial loads
Fast response: High efficiency and quick compensation
Excellent waveform quality: No harmonic injection
DSP-based digital control: Stable and reliable operation
Expandable design: Advanced capacity expansion and modular structure
User-friendly display: TFT color multifunction panel
Low operation cost: Maintenance-free, long service life
Compact design: Small footprint, optimized for installation in constrained spaces

Model Description
