Sentinel Dual SDU (4-10 kVA) is a high-performance ON LINE UPS with unity power factor, parallel capability, and flexible tower/rack installation.
The Riello Sentinel Dual SDU is a higher-power variant of the Sentinel Dual family, providing 4 to 10 kVA of online double-conversion protection in a compact tower format. It is ideal for medium server rooms, clinics, telecom cabinets, and industrial control rooms that need stable, clean power with extended autonomy.
With a wide input window, excellent overload capability, and a choice of internal or external batteries, the Sentinel Dual SDU offers a dependable foundation for continuous operations.
Delivers up to 10 kVA in a compact tower, keeping the UPS unobtrusive while protecting substantial server, network, or industrial loads.
Generous overload capability handles inrush from motors, medical equipment, and large switching power supplies without transferring to bypass.
Matched external battery cabinets scale autonomy to hours when required, supporting sites with delayed or absent generator backup.
Standard serial and USB ports plus optional SNMP and Modbus cards integrate the UPS with modern IT and building management systems.
