Efficient UPS systems from Harland Simon

These are targeted at the generation of 'Clean Energy' products and the development of even more efficient UPS in the future. Current UPS's available have efficiency values of up to 96.5% in double conversion on-line mode.

In addition to offering products with very high efficiencies, we also look at offering other key features which also have an impact on the environment.

* Adaptive Battery Management - to lengthen the period between battery replacement and disposal programmes and reduce the wear on other consumables such as fans and capacitors
* Low Total Harmonic Distortion on the input side (THDi typical 3%) to reduce the impact on upstream equipment and a high input power factor (0.99pf)
* Adaptive Smart Mode Operation in which the UPS selects a mode of operation that matches the electrical characteristics of the mains power supply

Efficiency Levels must be at the highest possible levels to reduce the stress on Critical Power Supplies and minimise the effect on local ambient.
