Sentinel Dual (SDU) Range Extension
Riello UPS expands best-selling Sentinel Dual (SDU) range with three new models.

The latest additions to the series (SDU 4000, SDU 8000 TM, and SDU 10000 TM) increase the overall power range to 4-10 kVA.  

Already extremely popular with IT resellers, the Sentinel Dual range is designed to handle non-linear loads, making it the ideal choice for protecting mission-critical IT networks, electro-medical devices, and industrial machinery.  

These new versions complement the existing 5, 6, 8, and 10 kVA SDU already available. An additional advantage with the versatile SDU 8000 TM and SDU 10000 TM power systems is that they can run on either a three-phase or single-phase power input. 

Another major benefit of the SDU series is that up to three UPS can be installed together using a parallel card to either increase the capacity or add system redundancy. This gives end-users the opportunity to scale their UPS system as and when the time comes for expansion. 

All Sentinel Dual UPS deliver operating efficiency up to 95%, while users can select from a full range of programmable operational modes available such as ECO or Smart Active to enhance efficiency or boost performance. 

Offering flexible installation either as a freestanding tower or rack-mounted in 19-inch server cabinets, the SDU incorporates hot-swappable batteries for downtime-free maintenance.  

These uninterruptible power supplies are manufactured with the latest advanced components designed to ensure exceptional performance even at temperatures up to 40°C.  

Noise levels are minimised thanks to intuitive digitally-controlled fans, whose speed is linked to the load levels.
