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

MPS300K-50K large scale 3 phase data center 300kva modular ups systems

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.
