Lower-power users now have the choice of a 10 kW UPS from ABB which features what the company calls double conversion.

Designed for single-phase applications, the PowerValue 11T G2 first converts incoming AC to DC from which the output AC is then synthesized.

This, it says, isolates the output voltage waveform from any disturbance in the input AC, guaranteeing clean power. ABB says the new tower-only model has an efficiency of up to 95 per cent plus further gains by adjusting to match the load.

Suggested uses are for server rooms, advertising displays, turnstiles, lab equipment, transport signalling systems, ATMs and vending machines.

Up to three units can be connected in parallel for redundancy or for power delivery of up to 30 kW and up to four optional external battery modules (EBMs) can supplement inbuilt batteries to extend runtime to a claimed two hours plus.
