Riello UPS Sentinel Rack SER 3000 ER - UPS (rack-mountable) - AC 220/230/240 V - 2700 Watt - 3000 VA - 1-phase - RS-232, USB - output connectors: 9 - 2U - black SER 3000 ER

The Sentinel Rack is a rack-mounted version of the popular Sentinel Pro range of online uninterruptible power supplies. Advanced double conversion technology provides the highest levels of reliability and protection for critical servers, data processing IT systems, and telecoms networks. Available in 1500 VA and 3000 VA versions, both products sit at just 380mm deep, making them the ideal choice to upgrade power in server rooms housing 600mm deep legacy racks.\nFor applications requiring several hours’ autonomy, the SER 3000 ER is fitted with a 6A battery charger and additional battery packs for extra runtime. These plug and play UPS systems are designed to fit standard 19 inch cabinet racks and incorporate a Cold Start feature that enables them to power up even if there isn’t a mains supply. Choose from a wide range of operating modes (i.e. Online, Eco, Smart Active, Standby Off, Frequency Converter) to boost performance and improve energy efficiency.
