# **Medium-Voltage UPS Product Overview**

## **1. Product Overview**

The medium-voltage UPS is a high-capacity power protection system designed for large industrial facilities and mission-critical loads. Operating at voltage levels from **6.6 kV to 24 kV**, it ensures continuous, uninterruptible power and prevents production downtime caused by grid disturbances such as voltage dips, sags, flicker, and short interruptions.

Built on the advanced **ZISC (Impedance-Isolated Static Converter) architecture**, the system delivers exceptional reliability, high efficiency, and ultra-fast switching performance. It is an ideal continuity-of-power solution for modern factories, power-sensitive industries, and large-scale infrastructure.

## **3. Working Principle**

The medium-voltage UPS is installed directly on the MV distribution bus. Using the ZISC topology, it continuously monitors the input power quality in real time.

When disturbances such as:

* Voltage dips
* Flicker
* Short interruptions
* Frequency anomalies
  occur, the system **switches to internal energy storage within milliseconds**, ensuring downstream critical loads receive a clean, stable sine-wave power supply with **zero interruption**.

## **4. Typical Applications**

The MV UPS is designed for industries where continuous operation is essential and power outages cause substantial losses:

### **🏭 Steel & Metallurgy**

Protects EAFs, CCMs, drives, and plant-wide control systems from sudden voltage dips.

### **⚙️ Large Mines & Smelting Plants**

Ensures continuous operation of hoists, compressors, ventilation systems, and mineral processing equipment.

### **🖥 Data Centers**

Provides high-reliability medium-voltage power protection and reduces PUE; replaces large LV UPS clusters.

### **⛽ Oil & Gas**

Supports pump stations, central control rooms, SCADA, and mission-critical communication systems.

### **🏥 Hospitals / Airports / Metro Systems**

Safeguards essential loads such as signaling systems, dispatch centers, elevators, and operating theaters.
