Logging and time-stamping (cont.)

The battery capacity is the value measured by the UPS microprocessor. It is expressed in Ampere-hours.

This value changes over time depending on the parameters of the battery itself and its environment. This measurement is used to check that the battery is capable of supplying the rated power in the event of a mains outage.

The backup time is the value calculated by the UPS microprocessor on the basis of measurements carried out on the battery. It is expressed in minutes. The calculation uses the percent load and the battery charge status at the time of the measurement.

The load level is the ratio between the power supplied by the UPS to the load at the time of the measurement and the rated output of the UPS. It is expressed as a percentage.

Utilisation via

Teleservice

When the optional JBUS RS232/485 communications board is installed, the time-stamped information can be sent to the Teleservice centre.

The centre can remotely consult the same information and carry out the same modifications as the user locally on the display. Note that only the Teleservice centre can reset the counters for the statistical data.
