Independent LCD for Each Power Module

Each power module has an independent LCD, gives users’ direct overview of status data and alarms in real time.

Friendly Interface

Provide graphical and text based information of alarms, status data, instructions that users can have more friendly and safer operation.

Isolated Air Flow

The dedicated and redundant hot-swappable power modules take the most unique structure design. In this design, the PCB boards and heat-sinkers are in two completely different layers, which allows the UPS run in dusty environments, significantly improving its stability and environmental adaptability. 

Cooling air flows in the lower layer, keeping the upper PCB free of dust

One air flow channel ensures fans redundancy, even one fan fails, power module can run normally

Unique Design for High Reliability

Instead of discrete IGBT and SCR components, RM series UPS uses modular IGBT and SCR in Rectifier and Inverter, bringing in extremely high reliability.

All components in one module, less fault points, higher reliability

All components integrated as one modular design, smaller disparity

Less space needed, UPS with compact design and higher power design

Integrated inner thermal sensors display IGBT inner temperature directly

High Density, Modular, Scalable

High power density, footprint for 300kVA is 0.66m², power density 409kW/m², saving valuable data center space

Scalable from 30kVA to 900kVA, max 30 power modules in parallel

Inherently N+X redundant

Hot swappable power module and bypass & monitoring module

Additional charging module, extra charging current 50A×N for long time back up application

Comprehensive Monitoring Management

In each power module, information of critical components is monitored and displayed in real time, giving customers a view of inner status of the system and providing reminder information for maintenance.

Maintenance reminder, running time of capacitors and fans displayed and recorded

Comprehensive temperature monitoring for thermal abnormal detection

Intelligent battery charger for long battery life

Critical Waveform Recording

UPS can record and save the data of the main parameters automatically when faults happen for further analysis.

Can record data information and present as waveform for further analysis

Can easily spot the causes of the failures, avoid future similar faults

Smart Sleep

Smart Sleep function can intelligently make some power modules go to sleep when load is relatively low, improving the efficiency of the remaining power modules and saving customers on power and cooling costs.

Improving efficiency, reducing power and cooling costs Easy setting with just two steps. Customers can select sleep mode and rotation period

Power modules working in rotation, prolong the life time


Self-aging is an advanced function applied in all three phase UPS, self-aging function can test UPS under different load situation without real load, saving more than 90% of energy.

Simulate different load conditions without connecting to any real load, saving 90% of energy On site setting supported, easy for factory testing

Programmable Dry Contacts

Programmable dry contacts are available in all RM and HT33 series UPS. Customers can easily expand or modify the definition of each port.

Abundant options with three inputs and four outputs, all programmable

Easy setting, just pull the drop-down menu and set

Compatible with all the RM and HT33
