Prism Power is the exclusive UK & Eire provider of innovative rotary-diesel UPS systems manufactured by KST of Belgium. KST Cleanwave® KPS UPS systems can be installed in plant-room environments or containerised as a continuous power system. There is no requirement for air-conditioning with the KST machine, not even power electronics, which adds greatly to the energy saving and reliability of the finished project.
The principle of operation is simplicity itself. Energy is stored in a flywheel whilst the grid power is present and, when the grid fails, released to maintain the load at the precise voltage and frequency for the stored energy autonomy time. The 'Rotabloc' machine stores enough energy to support the critical load for:
• 12 seconds at full, 100%, load
• 17 seconds at a typical 70% Tier III load
• 40 seconds at a typical 30% Tier IV load
For machines rated at less than 320kW/400kVA the autonomy time can be considerably extended if required.
The autonomy time is more than sufficient to start a standby generator in a relaxed condition - thus achieving a continuous power system without batteries, power electronics, power capacitors and an aggressive starting regime on the diesel engine.
