The Riello Sentinel Dual SDH ER 3000VA/2400W is a high-density 2U high double-conversion online uninterruptible power supply with a built-in automatic bypass, for server rack or floor standing tower installation. The SDH ER model has a high capacity charger and can be installed with battery extension packs to provide runtimes up to several hours.

The Sentinel Dual is an energy efficient UPS system with a 0.9 output power factor, and three operating modes including Online, Eco mode (up to 98% energy efficient) and Smart Active where the UPS automatically selects the best operating mode dependent upon the mains power supply quality.

The front panel backlit LCD display provides operating status information including load and battery levels, and alarm information. A dedicated EnergyShare socket outlet allows for load shedding when on battery, to increase the available runtime and provide sufficient runtime for a controlled computer/server shutdown using PowerShield3 UPS monitoring software (free download).
