The Riello Sentinel Dual 3kVA (3000VA) UPS with 4 minutes runtime provides on-line power protection and a highly regulated and stabilised output sinewave supply.
The SDH300 UPS has a rear panel battery extension pack connector to extend its runtime with the battery charged by the charger built-into the UPS. For longer runtimes use the 3kVA ER Sentinel Dual UPS. ER-models do not have an internal battery and this space is used to house a larger battery charger.
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.
See our extended battery runtime tables or contact us for a load specific runtime calculation.
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
