AC Uninterruptible Power Systems

PDF version

The Uninterruptible Power Systems (UPS) are widespread in the European Industry and service centres. Expectations are that UPS will increase in European Community in the near
future. The energy supply with UPS generates energy losses that are higher than the supply of the consumer direct from the low voltage network. With the general principles and actions resulting from the implementation of this Code of Conduct the additional electricity energy losses caused by UPS will be limited.

The energy losses caused by UPS are not to be neglected by EU energy and environmental policies. It is important that the electrical efficiency of UPS is maximised.

To help all parties to address the issue of energy efficiency whilst avoiding competitive pressures to raise energy consumption of equipment all manufacturers of UPS are invited to
sign this Code of Conduct. Taking into account that the energy efficiency of UPS is influenced by the quality realised, the mode of operation as well as the components used.

This Code of Conduct sets out the basic principles to be followed by all parties involved in Uninterruptible Power Systems, operating in the European Community in respect of energy
efficient equipment.
