400kVA UPS System Key Features

True Hot-Swappable Modular Design

The 400kVA UPS system utilizes a modular chassis that houses individual power modules (rated at 50kW/kVA each). If a module fails, the system reduces repair time to zero. Non-technical staff can replace faulty modules on-site in under five minutes. This process does not require transferring the load to bypass or powering down critical IT equipment.

Scalable Capacity (50kW to 600kW)

Start small and invest as you grow. The system allows for capacity upgrades by simply adding 50kW modules into the common frame. This “pay-as-you-grow” model eliminates over-provisioning and reduces the initial capital expenditure.

High Efficiency (Online Mode)

Peak Efficiency: Up to 95.5% in double-conversion mode.
Eco-Mode Efficiency: Up to 98.5%.

The high efficiency reduces heat dissipation. It lowers cooling requirements and operational costs. As a result, there is a lower TCO (Total Cost of Ownership) and PUE (Power Usage Effectiveness) for your facility.

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 the event of a failure, only the specific faulty 50kVA module needs to be replaced, not the entire 400kVA unit. Hot-swappable modules are easier to repair or refurbish individually. This modular approach drastically reduces the volume of e-waste sent to landfills compared to monolithic systems where a single component failure might necessitate scrapping a massive unit.

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 600kVA 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.

Redundant design and hot-swappable components allow maintenance without interrupting the protected load, significantly improving system availability.

LCD Display

The 7-inch touch LCD display is integrated into 400kVA ups system. 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.
