Carte de batterie de résérve

The Plug-in Battery Backup Card provides DC power to the 5-card Shelf or the 8-card Shelf in the event of a power interruption.

The unit indicates the battery charge status via a front panel LED, and provides front panel test jacks for direct measurement of the battery voltage under load/no-load conditions. A momentary contact push-button on the front panel enables the introduction of a test load on the batteries to permit accurate LED indications when the Battery Backup Card is not actually powering the shelf.

The Battery Backup Card is normally kept recharged by the Plug-in Power Supply card, Model 751313, 751316, or 751324
