1. Green and energy saving product, state of the art design 

RM series modular UPS system - 10KVA to 200KVA Advanced Modular Design and Redundant Power System 

RM series is modular and online double conversion UPS for sensitive equipments. The power rating covers from 10KVA to 200KVA which delivers the best of combination of reliability, functionality, hot-swappable and flexibility at a competitive price. It is designed specifically for data centers, computer systems or critical equipments. As the result of state of the art design, this innovative and reliable power system absolutely commits to satisfy and meet the market requirements.

RM series modular UPS combines the latest IGBT three-level technology together with DSP control arithmetic. Along with high input power factor, low THDi and high system efficiency, this product achieves very high load adaptability for all kinds of load. The Modular design ensures reliable and trouble free operation for the critical loads. Power expansion is very easy to achieve by adding power modules to the system and reach 200KVA power in single frame. It is possible to connect two frames in parallel in order to reach maximum 400KVA power.

2. Modular Construction Design

Each power module is designed be hot swappable which makes the power expansion and system maintenance easily. Each module is controlled independently, thus avoid single point failure risk. If any module fails or disconnected, the system keeps continuing to operate and supply the power without interruption. It ensures to provide a high level of reliability and protection.

3. Easy Operation and Installation

This product offers flexibility to install that reduces installation time. Consequently, it is very easy to maintain and control that provides the highest reliability and best protection for supplying power. With the large touch screen LCD panel, the user can easily access to the information of the power module and the system.

4. Intelligent Battery Management

Each UPS module builds in with super charger and the power reaches 3200W. With 10 installed UPS modules, the total charging power rating is up to 32KW. The charger is controlled by DSP with intelligent digital arithmetic thus to prolong the life time of the battery.

5. Intelligent Protection System

All the power modules and the system are protected simultaneously by the hardware and the software. All kinds of protection functions are realized, including current and voltage abnormal, thermal abnormal, short circuit, etc. The reliability of the power module and the system reaches an incredible high level through all of these technologies.

High reliability design

Integrated IGBT modules are used in the power module. Comparing to discrete chips, system reliability and manufacturing consistency are much improved. Low-loss integrated three-level IGBT modules help to increase system efficiency. Meanwhile reliability is increased due to lower temperature rising on IGBTs and heatsink. More chips need to be paralleled to realize high current rating if using discrete IGBT chips. Clamped Diodes should be placed around IGBTs which brings risk for voltage/current stress issues and manufacturing process.
