High Efficiency Power Conversion
The Sentinel Dual operates in online double conversion mode, achieving up to 95% efficiency while maintaining consistent voltage regulation. This ensures minimal energy waste while delivering clean, stable output for sensitive equipment, even during fluctuating input conditions.
Flexible Installation Design
Designed for adaptability, the unit can be deployed either as a 3U/6U rackmount system or a standalone tower. This versatility allows seamless integration into server rooms, edge environments, and industrial setups where space optimisation is essential.
Scalable Power Architecture
Up to three Sentinel Dual units can be connected in parallel, enabling scalable power capacity or redundancy configurations. This makes it suitable for growing infrastructure where uptime and expansion flexibility are critical requirements.
Advanced Battery System
Equipped with VRLA AGM maintenance-free batteries, the system supports hot-swap replacement for minimal downtime. Typical recharge time ranges from 4 to 6 hours, ensuring fast recovery after discharge events.
Output Performance and Load Handling
With a rated output of 6000 VA / 6000 W and a crest factor of 3:1, the UPS is engineered to support non-linear loads efficiently. It maintains low harmonic distortion and stable sinusoidal output, making it suitable for sensitive and high-demand equipment.
Environmental and Acoustic Control
Operating within a 0°C to +40°C range and humidity tolerance of 5–95%, the system is built for robust environmental performance. Adaptive fan control ensures low acoustic output, maintaining operational noise below 48 dBA in ECO mode.
Connectivity and Monitoring
The UPS includes USB and RS232 communication ports, along with a dedicated slot for optional interface cards. A rotating LCD panel provides real-time insights into load levels, battery status, and system performance.
Compact Engineering and Build
With a footprint of 448 x 131 x 640 mm in tower format (3U x 19” rack equivalent), and a weight of 20 kg, the Sentinel Dual is engineered for compact yet powerful deployment in constrained environments.
