ICT resource grows, more modules can be plugged into the rack to instantly expand UPS capacity. This can be done without need for more floor space or extra cabling – and the whole upgrade can be performed without having to interrupt power to the ICT equipment.
For example, Uninterruptible Power Supplies Ltd’s PowerWAVE 8000DPA, 9000DPA and 9500DPA families implement these modular, scalable solutions at different power levels.
PowerWAVE 8000DPA modules rated at 10 or 20 kVA each are available, while those for PowerWAVE 9000DPA are rated from 10 to 50 kVA, with PowerWAVE 9500DPA using modules rated at 100 kVA.
This allows solutions to be scaled from 10 kVA all the way up to 500 kVA, simply by populating a single PowerWAVE cabinet with appropriate modules. This is referred to as vertical scalability.
Larger installations can also adopt a ‘horizontal scalability’ solution, comprising a number of cabinets paralleled together and populated to meet the total critical load.
Modern UPS address the most urgent issues facing data centre and ICT equipment operators today: How to achieve great energy efficiency from a minimum floor footprint – and how to preserve these advantages while supporting unpredictable growth in demand for ICT resource.
