Annex AA
(normative)
Methods of efficiency measurement for UPS
AA.1 Introduction
This annex is intended to give the detailed UPS efficiency measuring method and conditions. This method
shall be used also for the efficiency test specified in 6.3.10. The definition of efficiency given in 3.3.19 (ratio
of output active power to input active power under specified conditions with no significant energy transfer to
and from the energy storage means) applies.
AA.2 Measurement conditions
The efficiency measurement shall be carried out as type test (see 3.2.39) under the following conditions:
AA.2.1 Environmental conditions
The environmental conditions shall be within the limits specified in 4.1. The following conditions also apply:
1) ambient temperature between 20 °C to 30 °C;
2) elevation between 0 m and 1 000 m above sea level.
AA.2.2 Operational and electrical conditions
The following conditions apply during the measurement:
1) the UPS shall be in Normal Mode (see 3.2.13);
2) there shall be no significant transfer to and from the energy storage
