RM Series Modular Online UPS
Three Phase 380V / 400V / 415V
The INVT RM Series Modular Online UPS is a high-reliability and highly adaptable power protection solution designed for medium to large data centers, telecommunications facilities, enterprise IT environments, and other mission-critical applications.
Developed as an upgraded generation of the earlier 20–200 kVA RM platform, this series is available in 150 kVA, 250 kVA, 500 kVA, and 600 kVA configurations, with system capacity scalable up to 900 kVA.
The RM Series combines modular IGBT technology, isolated airflow architecture, hot-swappable power modules, comprehensive monitoring, N+X redundancy, Smart Sleep operation, and advanced fault recording to provide high system availability, flexible capacity expansion, and dependable operation in demanding environments.
Key Features
- High Reliability & Environmental Adaptability – Modular IGBT and SCR architecture reduces potential failure points, while isolated airflow helps improve operation in dusty and demanding environments.
- High Power Density – A 300 kVA system occupies approximately 0.66 m², helping minimize valuable data center floor-space requirements.
- Scalable up to 900 kVA – Supports up to 30 power modules operating in parallel, providing flexible capacity expansion as load requirements increase.
- N+X Redundancy – Modular architecture allows additional power modules to be configured for redundancy, improving overall system availability.
- Hot-Swappable Architecture – Power modules and bypass & monitoring modules can be serviced with minimal impact on critical loads.
- Independent LCD for Each Power Module – Each power module is equipped with its own LCD display, providing direct access to real-time operating data and alarms.
- Smart Sleep Function – Intelligently places selected power modules into standby during low-load conditions to improve system efficiency and reduce cooling costs.
- Self-Aging Function – Allows the UPS to be tested under simulated load conditions without a conventional external load bank, reducing test energy consumption by more than 90%.
- Comprehensive Monitoring – Continuously monitors critical components, temperatures, operating hours, alarms, and maintenance indicators.
- Programmable Dry Contacts – Provides flexible integration with external monitoring, alarm, and building-management systems.
Independent LCD for Each Power Module
Each power module incorporates an independent LCD display, allowing users to monitor the module directly without relying solely on the main system interface.
The display provides real-time visibility of:
Operating Status • Alarm Information • Key Parameters • Internal Conditions • Maintenance Information
This module-level monitoring simplifies troubleshooting and helps service personnel quickly identify abnormal operating conditions.
User-Friendly System Interface
The main system interface provides both graphical and text-based information, including alarms, operating status, system data, and instructions.
This intuitive interface improves visibility of the UPS operating condition and enables safer, more convenient daily operation.
Isolated Airflow Design
The RM Series adopts a dedicated isolated airflow architecture designed to separate sensitive control electronics from the main cooling airflow.
The PCB assemblies and heat sinks are positioned in separate layers, allowing cooling air to flow through the lower section while helping keep the upper PCB area protected from dust contamination.
Key advantages include:
- Improved Dust Resistance
- Enhanced Environmental Adaptability
- Effective Thermal Management
- Reduced Dust Exposure for Sensitive Electronics
- Cooling Fan Redundancy
The cooling architecture also provides fan redundancy so that, under supported operating conditions, the power module can continue operating even if one cooling fan fails.
Integrated IGBT & SCR Design
Instead of using multiple discrete IGBT and SCR components, the RM Series adopts integrated modular IGBT and SCR devices in the rectifier and inverter sections.
This integrated architecture helps provide:
Fewer Potential Failure Points • Higher Reliability • More Consistent Performance • Reduced Internal Complexity • Compact Construction • Higher Power Density
Integrated internal thermal sensors also allow direct monitoring of IGBT operating temperature, providing additional visibility into the thermal condition of the power module.
High Density, Modular & Scalable
The RM Series is engineered to provide high power capacity while minimizing equipment-room footprint.
A 300 kVA system occupies approximately 0.66 m², providing a stated power density of approximately 409 kW/m².
The modular architecture is scalable from 30 kVA up to 900 kVA, with support for up to 30 power modules operating in parallel.
Additional advantages include:
- Inherent N+X Redundancy
- Hot-Swappable Power Modules
- Hot-Swappable Bypass & Monitoring Modules
- Flexible Capacity Expansion
- Additional Charging Modules for Long-Backup Applications
- Extra charging capability of up to 50 A × N, depending on the selected configuration.
Comprehensive Monitoring Management
The RM Series provides detailed real-time monitoring of critical components within each power module.
Monitoring functions include:
- Capacitor Operating Time
- Fan Operating Time
- Maintenance Reminders
- Comprehensive Temperature Monitoring
- Thermal Abnormality Detection
- Intelligent Battery Charging
- Critical Component Status Monitoring
These functions support preventive maintenance and help operators identify developing issues before they become more serious system faults.
Critical Waveform Recording
When a fault or abnormal operating condition occurs, the UPS can automatically record key operating parameters for further technical analysis.
Recorded data can be presented as waveform information, allowing engineers to review the condition of the system at the time of the event.
This diagnostic capability helps:
Accelerate Troubleshooting • Identify Root Causes • Improve Fault Analysis • Reduce the Risk of Recurring Problems
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 at a more efficient load level, helping reduce:
Electrical Losses • Energy Consumption • Cooling Demand • Operating Costs
Users can configure both the sleep mode and module rotation period. Power modules can operate in rotation to balance operating hours across the system and help extend overall module service life.
Self-Aging Function
The RM Series includes an advanced self-aging function that allows the UPS to be tested under different simulated load conditions without connecting a conventional external load.
By internally circulating energy during testing, the system can reduce test energy consumption by more than 90%.
This provides several benefits:
Reduced Energy Consumption • Lower Heat Generation • Reduced Load-Bank Requirements • Easier Site & Factory Testing • Lower Commissioning Costs
Programmable Dry Contacts
Programmable dry contacts are available across selected RM and HT33 Series UPS systems, providing flexible integration with external monitoring and control systems.
The system provides:
- 3 Programmable Inputs
- 4 Programmable Outputs
- Flexible alarm and control assignments
- Easy configuration through the system interface
- Integration with BMS, EMS, alarm systems, and other facility monitoring platforms
