25kVA-250kVA Modular UPS

How the Modular UPS Works

During normal utility operation, the incoming AC power enters the UPS rectifier and is converted into DC power. The DC bus supplies the inverter, which then produces stable AC output for the connected equipment.

Because the system uses online double conversion, the load is continuously supplied through the inverter rather than directly from the utility input. This helps reduce the effect of voltage fluctuations, electrical noise and other common power-quality disturbances.

The battery is maintained in a charged state while utility power is available. If the utility power fails, the battery takes over the DC supply to the inverter without requiring a manual transfer, allowing the UPS to continue supporting the load.

The 25-250kVA system uses multiple power modules to achieve the required output capacity. Modules can operate together and, depending on the system configuration, additional modules can be used to provide redundancy or support future capacity requirements.

Key Features

Optimized for 25-250kVA Applications

With a 25-250kVA capacity range, this UPS provides a practical solution for facilities whose power requirements fall between smaller standalone UPS systems and larger high-capacity installations.

Capacity That Can Grow with the Load

The modular design allows the system to be configured around actual power requirements. When the facility adds servers, equipment or additional electrical loads, the UPS can be expanded accordingly rather than being replaced by an entirely new system.

Improved Power Availability

The system can be configured with redundant modules to provide additional operating capacity. This N+X architecture helps support continuous operation for applications where power availability is an important requirement.

Efficient Operation & Space Planning

A modular UPS allows system capacity to be planned more precisely around the actual load. This can help avoid excessive initial capacity and make better use of available equipment-room space.

Centralized Intelligent Management

DSP-based digital control manages the operation of the UPS system, while communication options such as RS485 and optional SNMP can support remote monitoring and system management.

Applications

Small and Medium-Sized Data Centers

The 25-250kVA modular UPS is well suited to small and medium-sized data centers that require dependable power protection without deploying an unnecessarily large UPS system. Its modular configuration makes capacity planning more flexible as IT loads change.

Corporate Server Rooms

For corporate server rooms supporting applications, databases, communications and network infrastructure, the UPS provides stable online power protection. The scalable architecture allows the power system to develop alongside the company's IT requirements.

Commercial Buildings

Shopping centers, office buildings and commercial facilities can use the UPS to protect communication systems, IT equipment, security systems and other important loads. Its modular configuration provides a practical approach to managing changing electrical requirements.

Healthcare & Service Facilities

Hospitals, clinics and other service-oriented facilities rely on continuous power for electronic equipment and critical information systems. The UPS provides conditioned power and backup capability for loads where unexpected power interruptions can affect operations.

Light Industrial Applications

The UPS can support automation equipment, control systems, monitoring devices and other sensitive electrical loads in light industrial environments. Reliable power protection helps reduce interruptions caused by unstable utility conditions.
