300kVA Modular UPS Key Features

Modular Architecture

300 kVA power modules with hot-swappable 50 kVA submodules enable non-disruptive capacity upgrades and simplified maintenance.

High Power Density

Delivers unity output power factor (PF=1.0), meaning 300kVA = 300kW usable power, optimizing space and efficiency in modern data centers.

Hot-Swappable Power Modules

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

Fast Transfer & Low Inrush Impact

Sub-millisecond transfer times and soft-start capability reduce downstream stress and maintain uptime for sensitive IT equipment.

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.

Intelligent Battery Management

Integrated battery monitoring, temperature compensation, and support for various battery types (VRLA, Li-ion) extend battery service life.

Modular Design for Flexible Expansion

In large-scale data centers, uninterrupted power is critical. The MPS300K-50K 300kVA modular ups can provide exceptional system reliability:

True online double-conversion topology
N+X redundancy at module level
Independent control system for each module
Intelligent load sharing among modules
Fault isolation to prevent single-point failure

With redundant design and hot-swappable components, maintenance can be performed without interrupting the protected load, significantly improving system availability.

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.

High Scalability for Growing Data Centers

The MPS300K-50K adopts a 50kVA / 50kW power module design. This design enables flexible system configuration. Capacities range from lower levels up to 600kVA within a single cabinet. Additional cabinets can be paralleled for even higher power demands.

Power module: 50kVA / 50kW
System capacity: Up to 300kVA per cabinet
Parallel expansion capability for large power systems
Hot-swappable power modules without downtime

This modular architecture allows data center operators to invest according to current needs. It maintains the flexibility to expand as business grows.

With redundant design and hot-swappable components, maintenance can be performed without interrupting the protected load, significantly improving system availability.

LCD Display

The 7-inch touch LCD display is integrated into 300kVA modular UPS. 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.
