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 180 kVA, 300 kVA, and 600 kVA configurations, with system capacity scalable up to 900 kVA.
The RM Series combines a modular IGBT architecture, isolated airflow design, hot-swappable power modules, intelligent monitoring, N+X redundancy, smart sleep operation, and advanced fault recording to provide dependable performance, high scalability, and strong adaptability to demanding operating 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 reduce valuable data center floor-space requirements.
- Scalable up to 900 kVA – Supports up to 30 power modules operating in parallel, allowing flexible system expansion as load requirements grow.
- N+X Redundancy – Modular architecture provides inherent redundancy for improved system availability.
- Hot-Swappable Architecture – Power modules as well as bypass and monitoring modules can be serviced with minimal impact on critical loads.
- Independent LCD for Each Power Module – Each power module incorporates its own LCD, providing real-time visibility of module status and alarms.
- Smart Sleep Function – Automatically places selected power modules into standby during low-load conditions to improve operating efficiency and reduce cooling costs.
- Self-Aging Function – Enables UPS testing under simulated load conditions without requiring a conventional external load, reducing test energy consumption by more than 90%.
- Comprehensive System Monitoring – Critical components, temperature conditions, running hours, alarms, and maintenance indicators are continuously monitored.
- Programmable Dry Contacts – Provides flexible alarm and control integration with programmable inputs and outputs.
Independent LCD for Each Power Module
Each power module is equipped with an independent LCD display, providing operators with direct access to important real-time information.
The display allows users to monitor:
Module Operating Status • Alarm Information • Key Parameters • Internal Conditions • Maintenance Information
This module-level visibility simplifies troubleshooting and improves maintenance efficiency.
User-Friendly System Interface
The main system interface provides both graphical and text-based information, allowing operators to monitor alarms, system conditions, operating data, and instructions in a clear and intuitive format.
This helps simplify daily operation and improves visibility of the overall UPS system.
Isolated Airflow Design
The RM Series adopts a dedicated isolated airflow architecture that separates sensitive electronic components from the main cooling airflow path.
PCB assemblies and heat sinks are positioned in separate layers, with cooling air directed through the lower section of the power module. This helps reduce dust accumulation on sensitive control electronics.
Key advantages include:
- Improved Dust Resistance
- Enhanced Environmental Adaptability
- Better Thermal Management
- Reduced Contamination of PCB Assemblies
- Fan Redundancy within the Cooling Channel
Even if one cooling fan fails, the power module is designed to continue operating under supported conditions, improving overall system resilience.
Integrated IGBT & SCR Design
Instead of relying on multiple discrete IGBT and SCR components, the RM Series uses integrated modular power devices in both the rectifier and inverter sections.
This design helps deliver:
Fewer Failure Points • Higher Reliability • More Consistent Component Performance • Compact Construction • Higher Power Density
Integrated thermal sensors also allow direct monitoring of the internal IGBT temperature, improving visibility of thermal operating conditions.
High Density, Modular & Scalable
The RM Series is designed to deliver high power capacity while minimizing floor-space requirements.
A 300 kVA system occupies approximately 0.66 m², providing a high power density of approximately 409 kW/m².
The architecture is scalable from 30 kVA up to 900 kVA, with support for up to 30 power modules in parallel.
Additional features include:
- Inherent N+X Redundancy
- Hot-Swappable Power Modules
- Hot-Swappable Bypass & Monitoring Modules
- Flexible Capacity Expansion
- Additional Charging Modules for Extended Backup Applications
- Extra charging capacity of up to 50 A × N, depending on configuration.
Comprehensive Monitoring Management
The RM Series provides detailed real-time monitoring of critical components within each power module.
System monitoring includes:
- Operating Time of Capacitors and Fans
- Maintenance Reminder Functions
- Comprehensive Temperature Monitoring
- Thermal Abnormality Detection
- Intelligent Battery Charging
- Component Operating Status
These functions support preventive maintenance and allow operators to identify abnormal conditions before they develop into more serious system faults.
Critical Waveform Recording
When an abnormal condition or fault occurs, the UPS can automatically record key operating parameters for further technical analysis.
Recorded information can be presented as waveform data, helping engineers identify the sequence and possible cause of an event.
This diagnostic capability helps:
Speed Up Troubleshooting • Identify Root Causes • Support Preventive Analysis • Reduce the Risk of Repeated Faults
Smart Sleep Function
During periods of relatively 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, reducing both electrical losses and cooling requirements.
Operators can configure the sleep mode and module rotation period according to site requirements.
Power modules can also operate in rotation, helping balance operating hours across the system and potentially extending overall module service life.
Self-Aging Function
The RM Series includes an advanced self-aging function for system testing and commissioning.
This feature allows the UPS to simulate different load conditions without connecting a conventional external load.
By internally circulating energy during the test process, the system can reduce test energy consumption by more than 90%.
This provides several advantages:
Reduced Energy Consumption • Lower Heat Generation • Reduced Load-Bank Requirements • Easier Factory & Site Testing • Lower Commissioning Costs
Programmable Dry Contacts
The RM Series provides flexible programmable dry-contact functionality for integration with external monitoring and control systems.
The system offers:
- 3 Programmable Inputs
- 4 Programmable Outputs
- User-definable alarm and control functions
- Easy configuration through the system interface
- Compatibility across selected RM and HT33 Series platforms
This enables the UPS to be integrated easily with BMS, EMS, alarm systems, and other facility monitoring platforms.
