Riello UPS presents Sentinel Dual Marine (SMU), a compact and robust UPS designed to ensure continuous and reliable power supply in marine and offshore environments. Available in 6 and 10 kVA/kW models, the SMU combines online double conversion technology, high environmental resistance, and flexible installation to protect mission-critical onboard systems.

Engineered for demanding onboard conditions, it features an anti-vibration frame, conformal coating on internal PCBs, and operation guaranteed up to 45°C, ensuring resilience against mechanical stress, temperature variations, and harsh marine conditions.

Sentinel Dual Marine offers high flexibility with rack or tower installation, Plug & Play design, rotatable display, and maintenance bypass options, while allowing parallel operation of up to 3 units in capacity or N+1 redundant configuration for increased system reliability. Advanced operating modes (ONLINE, ECO Mode up to 98% efficiency, SMART ACTIVE, STANDBY OFF, and frequency converter 50/60 Hz) provide optimal performance and energy efficiency.

The system also includes advanced battery management with hot-swappable long-life batteries, runtime expansion via external cabinets, and reduced ripple current for improved battery durability. Comprehensive connectivity is ensured through USB, RS232, expansion slots, and PowerShield³ software compatibility across major operating systems.

Designed for mission-critical marine applications such as navigation, communication, and safety systems, Sentinel Dual Marine reinforces Riello UPS’s commitment to delivering robust, efficient, and reliable power protection solutions for the most demanding environments.
