Battery Backup Time

The exact amount of backup time provided will vary depending on the UPS model being used, number of batteries, condition of the batteries and other factors. However, the chart below gives the times that can be expected from the standard units with batteries in good condition. For greater backup time, an additional battery module may be added to the standard unit. Only one additional battery module may be added to the standard unit. For longer runtime options contact your Toshiba sales representative or the Toshiba marketing department at (800) 231-1412 or by e-mail at toshibaups@tic.toshiba.com.

Load Shed Function

The 1700 Series includes a load shed function. During battery backup operation, this function allows the load connected to two of the receptacles (figure 1, page 9) to be turned off in an effort to conserve power for more critical loads. The battery level at which these two receptacles will be turned off, or “shed”, can be set by the user (see “The Function Control Button”, page 16). By default, this feature is configured so that these two receptacles will remain on for the full battery backup time available (no “shedding”)

Battery Recharge Time

The following table gives estimates on time required to recharge the UPS’s batteries. The recharge time may vary depending on the battery temperature, the age of the batteries, and other factors.
