ABB launches new UPS for low power applications

April 13, 2018

Swiss engineering firm ABB has developed a single-phase UPS for lower power applications up to 30kW, such as server rooms, ad displays, vending facilities, and security gates.


Named PowerValue 11T G2, the new UPS system adopts ABB’s double conversion technology. ABB said incoming AC is first converted to DC, from which the output AC is then synthesised— providing a clean sinusoid.


ABB said the double conversion isolates the output voltage waveform from any disturbances on the input AC side—which means the system guarantees that the power is always clean, whether or not the UPS is connected.


Up to three 10kW units can be connected in parallel to provide redundancy or to boost power delivery up to 30 kW, the hardware for paralleling comes installed. In addition, up to four optional external battery modules can be added on the inbuilt batteries to extend runtime to over two hours.


According to the company, PowerValue 11T G2 saves costs by minimising energy losses with its double conversion efficiency of up to 98%. Further efficiency is achieved by voltage and frequency independent mode, in which the UPS activates and deactivates modules to match load requirements, thus saving energy and improving system efficiency especially in low-load conditions. 


Gabriele Poccia, product manager of ABB’s single-phase UPS product line, said: “ABB is now implementing additional UPS technology in lower-power products and this is having a very positive impact on our single-phase market.”
