RM Series Modular Online UPS
Three Phase 380V / 400V / 415V
The INVT RM Series Modular Online UPS is a cost-effective and highly scalable power protection solution designed for medium to large data centers, telecommunications facilities, enterprise IT infrastructure, and other mission-critical applications.
Available in 300 kVA, 400 kVA, and 500 kVA capacities, the series utilizes high-density 50 kVA power modules in a compact 4U design. A single cabinet can accommodate up to 500 kVA while occupying less than 1.45 m² of floor space, helping data center operators maximize valuable equipment-room space.
For larger installations, up to 3 UPS cabinets can operate in parallel, providing a total system capacity of up to 1,500 kVA.
With advanced three-level power conversion technology, modular scalability, intelligent battery management, Smart Sleep operation, comprehensive communications, and an intuitive HMI, the RM Series provides an efficient and flexible UPS platform for demanding critical-power environments.

High Power Density & Compact Footprint
The RM Series is designed to provide substantial UPS capacity while minimizing the physical space required for installation.
A single cabinet can support up to 500 kVA within less than 1.45 m², making it particularly suitable for data centers where floor-space optimization is a key design requirement.
The 50 kVA / 4U power-module architecture allows capacity to be expanded progressively according to actual load growth, helping avoid unnecessary initial over-sizing.
Scalable up to 1,500 kVA
The modular architecture allows the UPS system to grow together with the facility’s power requirements.
A single cabinet can be configured from 40 kVA to 500 kVA, while up to 3 cabinets can operate in parallel, providing a maximum total capacity of 1,500 kVA.
This scalable architecture provides flexibility for:
Future Capacity Expansion • Increased System Redundancy • Data Center Growth • Critical Load Expansion • Infrastructure Planning
High-Efficiency Three-Level Technology
The RM Series incorporates advanced three-level power conversion technology, achieving operating efficiency of up to 96% in online double-conversion mode.
Higher efficiency helps reduce:
Electrical Losses • Heat Generation • Cooling Demand • Energy Consumption • Overall Operating Costs
This makes the system particularly suitable for continuously operating data centers and critical facilities.
Intelligent Battery Management
The UPS intelligently manages the battery charging and discharging process to help maintain reliable battery performance throughout the operating lifecycle.
The intelligent charging management system helps:
Optimize Charging Performance • Maintain Backup Readiness • Improve Battery Reliability • Extend Battery Service Life
Smart Sleep Function
During periods of low load, the Smart Sleep function can automatically place selected power modules into standby.
This allows the remaining active modules to operate closer to their optimal efficiency range, improving overall UPS efficiency while reducing power and cooling costs.
As load demand increases, additional modules can return to operation to maintain the required system capacity.
Advanced Monitoring & HMI
The RM Series features a large 10.4-inch color touch LCD with graphical display for intuitive system monitoring and operation.
In addition, each power module incorporates an independent LCD, allowing operators to view individual module status and alarms directly.
This combination provides enhanced visibility of both the overall UPS system and individual power modules.
Communication & System Integration
The RM Series provides multiple communication options for integration with facility monitoring and management platforms.
Supported interfaces include:
RS232 • RS485 • USB • SNMP • AS400 • Programmable Dry Contacts
These communication options allow convenient connection to systems such as BMS, EMS, network monitoring platforms, alarm systems, and other facility-management infrastructure.
