Toshiba T1000 Series - battery enclosure - 1000 VA - lead acid - 9 Ah

As a double conversion on-line UPS, it is able to supply uninterrupted, clean single-phase power to your critical systems while keeping batteries charged continuously, regardless of whether utility power fails or not. In event that a power failure lasts longer than a UPS backup time, it will shut down avoiding battery discharge, and as soon as power comes back, the UPS will automatically charge up and start recharging the batteries.
