## Long description

Riello Sentinel Dual SDU 8 kVA is an online double-conversion uninterruptible power supply (UPS) designed for mission-critical applications and electro-medical devices that require high power reliability. This 8 kVA / 8000 W unit provides filtered, stabilised sinusoidal output through continuous inverter operation and offers flexible installation as a tower or rackmount with a rotatable display. The model includes multiple IEC output sockets (including C13 and C19 types), sealed lead-acid battery technology and complies with relevant standards for dependable backup power.
Advantages
The Sentinel Dual series delivers continuous ON LINE double-conversion protection with high output quality even for non-linear IT loads and a high overload capacity. It offers selectable operating modes (ON LINE, ECO, SMART ACTIVE, STANDBY OFF) to optimise efficiency up to 98% and automatic mode switching based on mains quality. EnergyShare load-shedding sockets and load-controlled fans reduce power use and noise (\<48 dBA). Installation is simplified by floor or rack mounting, a rotatable display, built-in thermal-protected IEC outlets and optional external bypass for uninterrupted maintenance.
Suitable for
Data centre racks and network equipment requiring rack/tower flexibility
Electro-medical devices and mission-critical instruments
Servers, storage systems and IT equipment with non-linear loads
Environments needing uninterrupted operation with maintenance bypass
