Modular UPS 200kVA Key Features

True Online Double-Conversion Topology

It continuously converts incoming AC power to DC. Then, it converts it back to pure AC. This process provides complete isolation from input disturbances, including surges, sags, noise, frequency variations, and harmonics. Output is always stable and clean, regardless of utility power quality.

Scalable Design

Start with the capacity you need today. Scale vertically by inserting additional modules as your power requirements grow. There is no need to replace the entire system.

Hot-Swappable Power Modules

The system utilizes high-density 50 kW (or 50 kVA) intelligent power modules.

High Efficiency

Operating in ECO mode can achieve efficiency levels of up to 98.5%, significantly reducing energy costs and heat generation.

LCD Touch Screen

Offers an intuitive user interface for easy monitoring and configuration, along with remote access for convenience and management.

Intelligent Monitoring

Equipped with a smart monitoring system, the modular ups 200kva provides real-time data on power usage, battery status, and overall system health through a user-friendly interface.

Supports Parallel Operation

Allows for increased capacity and redundancy by connecting multiple UPS units in parallel, suitable for growing data center needs.

Modular Design for Flexible Expansion

The modular UPS 200kVA guarantees uninterrupted power, ensuring the continuous operation of critical equipment and preventing costly downtime. High efficiency leads to reduced operational costs. The modular nature allows users to invest in additional capacity as needed. This can be done without a complete system overhaul.

This modular UPS is designed with 50kVA/50kW power modules, allowing fast installation and flexible upgrades. When a module needs maintenance, it can be replaced quickly. This is possible through a hot-swappable structure, which significantly reduces system downtime. It also helps lower maintenance costs.

7-inch LCD Display

The 7-inch touch LCD display is integrated into the modular UPS 200kVA. It is a user-friendly, high-resolution capacitive touchscreen interface. This interface is designed to provide intuitive real-time monitoring. It also allows control and configuration of the entire power system.

Intuitive Graphical Interface — Modern, icon-based layout with clear menus, real-time dashboards, and color-coded status indicators (green for normal, yellow for warning, red for fault/alarm).

Real-time Monitoring — Displays critical parameters such as:

Input/output voltage, current, frequency, and power (kVA/kW)
Load percentage and crest factor
Battery voltage, charge/discharge current, remaining runtime, and capacity
Inverter/bypass/rectifier status
Module status (each 50 kW power module)

Alarm & Event Management — Full fault records, operation logs, and predictive warnings with timestamps; supports detailed alarm descriptions and troubleshooting guidance.

Intelligent Battery Management System

The Intelligent Battery Management System (IBMS) in the modular UPS 200kVA is an advanced, microprocessor-controlled feature. It optimizes battery performance and extends service life, also enhances safety and ensures reliable backup power during outages. It actively monitors the external battery bank. The modular ups charges and maintains it. This ensures maximum runtime and minimizes total cost of ownership (TCO).

Periodic automatic battery discharge tests (user-scheduled or on-demand) verify actual backup capability without interrupting the load.
Equalization charging mode activates as needed to balance cell voltages and correct sulfation in lead-acid batteries.
Supports cold-start capability from batteries even if utility power is unavailable.
Works with external battery packs (lead-acid VRLA, flooded, or lithium-ion options in supported variants).
Integrates seamlessly with the UPS’s DSP-based control system for coordinated operation during transitions (e.g., smooth handover to inverter during blackouts).
