Modular UPS | 200kVA/200kW | 3 Phase 4 Wires | +/-192VDC~+/-240VDC | 4 x 50KW Power Module
Prostar MPS200K-50K double conversion modular power supply ups 200 kva designed for mission-critical applications demanding maximum uptime and scalability. With a total capacity of 200 kVA (scalable from 50 kVA modules), this UPS 200kVA delivers pure sine wave output. It utilizes true online double conversion technology. This ensures zero transfer time. It also provides complete isolation from power disturbances like surges, sags, and harmonics.
Hot-swappable 50 kVA power modules allow for easy expansion up to 200 kVA. They also provide N+1 redundancy. This setup minimizes downtime during maintenance or growth.

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.

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.

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