Sentinel Dual is the best solution for powering Mission Critical electro-medical applications and devices that require maximum energy reliability. The flexibility of installation and use (thanks to the digital display and user replaceable battery module) and the many communication options available make Sentinel Dual suitable for a wide variety of applications, from IT to security.

Sentinel Dual can be installed in parallel with up to three units to increase capacity or configured to operate in N+1 mode, increasing the reliability of critical systems.

Sentinel Dual can be floor standing in a tower configuration or rack mounted for network and server applications. The Sentinel Dual range is available in 4 kVA and 5-6-8-10 kVA/kW models with ON LINE double conversion (VFI) technology: the load is constantly fed by the inverter, which delivers a filtered sinusoidal voltage that is stabilized in terms of voltage, shape and frequency. In addition, input and output filters greatly increase the immunity of the load to mains disturbances and lightning strikes.

Technology and performance: ECO and SMART ACTIVE mode functions can be selected. Diagnostics: Standard digital display, RS232 and USB interfaces with downloadable PowerShield3 software, communication slot for connectivity accessories.
