Riello Sentinel Dual SDU UPS Double-conversion 10 kVA 10000 W 5 AC outlets

The Riello Sentinel Dual SDU is a double-conversion online UPS with 10 kVA / 10000 W capacity designed to provide continuous, stabilized sinusoidal power for mission‑critical systems and electro‑medical devices. The unit is available in rackmount or tower form factors and includes five AC outlets (C13/C19 types) and sealed lead‑acid battery technology. Certified to EN 62040‑2 and compliant with VFI (double conversion) performance class EN62040‑3, the Sentinel Dual SDU supports high reliability and reduced electrical disturbances.

Advantages

The Sentinel Dual SDU delivers a filtered, stabilized output voltage and high short‑circuit and overload capacity (up to 150% by inverter). It offers multiple operating modes (ON LINE double conversion, ECO, SMART ACTIVE, STANDBY OFF) to balance efficiency and protection, and includes EnergyShare load‑shedding sockets to prioritise critical loads. Installation is simplified by a rotatable display, low noise operation (<48 dBA), rack/tower mounting options and built‑in IEC output sockets with thermal protection. Additional features include external bypass for maintenance, dual input configuration on select models, back‑feed protection and firmware upgradeability via flash memory.

Suitable for

• Servers and network equipment in data rooms and server racks
• Electro‑medical devices and critical healthcare systems
• Telecommunications and control systems requiring uninterrupted power
• Industrial and IT installations that need reliable power conditioning

How to use

Install the SDU in a rack or place it as a tower on the floor, orient the display panel as required using the supplied key, and connect the critical loads to the IEC output sockets (C13/C19). Configure operating mode and parameters either via the front display panel or through the management software. For maintenance, use the external bypass option to allow interruption‑free switching. Ensure proper ventilation and connect the unit to a compatible mains supply; the UPS will supply conditioned power continuously while charging its internal sealed lead‑acid batteries.

Usage recommendations

Configure EnergyShare sockets to protect the most critical equipment first and enable load‑shedding for lower‑priority devices. Use ECO or SMART ACTIVE modes where appropriate to increase efficiency, but select ON LINE mode when you require maximum voltage and frequency regulation. Schedule periodic battery tests and firmware updates to maintain reliable operation.
