The Riello Sentinel Dual 3kVA Extended Runtime (ER) UPS are based on the standard SDH3000 but have a larger charger and no internal battery. Sentinel Dual ER models have to be connected to a separate matching battery extension pack (priced separately).
Please contact us for a load specific runtime calculation.
Sentinel Dual UPS have a dual tower/19inch rackmount format, and a front panel LCD that can turn 90degrees to suite the installation format. As part of the Riello UPS ECO Line range these uninterruptible power supplies have: a high operating efficiency, battery lifetime optimisation, energy saving shut-down with no load present and configurable eco-mode UPS options. A built-in automatic bypass provides further protection for critical loads in case the UPS inverter is overloaded or suffers a fault condition. The UPS is easy to install, with an informative front panel and rear panel connections.
Typical applications: critical data and voice processing applications requiring on-line (VFI) power protection and/or long duration runtimes, datacentre racks, Blade servers, comms rooms equipment, LAN servers.
