Modular scalable UPS RM FM series 25-250KVA

The high-frequency modular RM33-FM series 25-250kVA three-phase input and three-phase output UPS power supply adopts modular design and N+X parallel redundancy technology. The product capacity covers various power segments ranging from 25kVA to 250kVA, facilitating users to make flexible configurations and incremental investments. This series of UPS can almost completely address all power supply issues, such as power outages, high mains voltage, low mains voltage, momentary voltage drops, amplitude-damping oscillations, high-voltage pulses, voltage fluctuations, surge voltages, harmonic distortions, clutter interferences, frequency fluctuations, and other power supply problems.

Product Features

Digital Control

  • All components of this series of UPS are digitally controlled, resulting in outstanding performance across all indicators.

High Power Density Modular Design

  • Each single module has a capacity of 25kVA, and all modules are 2U in height. UPS modules can be inserted or removed while the system is online.

19-inch Standard Cabinet

  • It features a 19-inch standard cabinet, which is aesthetically pleasing and perfectly matches the application environment of the computer room.

N+X Parallel Redundancy

  • When the number of redundant modules is two or more, the system availability reaches 99.999%, and the MTBF (Mean Time Between Failures) exceeds 250,000 hours. It supports parallel operation of up to 4 cabinets, and the battery pack can be shared during parallel operation.

Intelligent Battery Management

  • Users can set the charging current. The charging modes can automatically and smoothly switch among constant – current, constant – voltage, and floating – charge modes. The number of batteries can be selected from 30 to 50.

LCD Color Screen Display

  • The cabinet is equipped with a large LCD display with touch-screen functionality. Both Chinese and English languages are available for selection.

Safe and Convenient Maintenance

  • In case of an emergency, the system can be switched to the maintenance bypass for power supply, allowing maintenance personnel to perform online maintenance safely. Pressing the EPO button in an emergency can shut down the system immediately. It also has a remote emergency shutdown (REPO) function.

Intelligent Management

  • The centralized monitoring module has a hot-swap function and an RS485 communication interface. Optional accessories such as SNMP cards, relays, and dry contact cards can be installed.
