Sentinel Dual Low Power (SDH) is a versatile UPS designed to deal with non-linear loads. It’s a proven solution for Edge applications, blade servers, VoIP equipment, IT networks, electro-medical devices, emergency lighting, and security/safety systems.
Install as either a freestanding tower or 2U rackmount UPS. Simply plug and play, no complicated setup. Enhanced inverter delivers 0.9 power factor and 92% efficiency. Easy maintenance with hot-swappable batteries. The doubly-versatile Sentinel Dual (Low Power) combines installation flexibility with fantastic functionality and ease of maintenance. The single-phase UPS comes in a variety of 4 power ratings (1000-1500-2200-3000 VA).
For critical business continuity applications requiring long runtimes, SENTINEL DUAL can be installed with battery extension packs (ER models) with their own internal battery chargers to maintain sensible recharge times. The UPS also incorporates the Riello UPS ‘power-off’ function found in other ECO Line UPS. Premium Dual is designed to save energy when no loads are connected.
SENTINEL DUAL can be programmed remotely via software or set manually from the front mimic panel to operate in a range of energy saving operating modes:
SENTINEL DUAL offers maximum flexibility for integrations with any communication system.
