Riello Multi Sentry 3/3 Phase UPS

Multi Sentry  3/3 Phase: High-Efficiency, High-Power Protection for Critical Infrastructure

Uncompromising Power Quality and Minimal Environmental Impact:

The Riello Multi Sentry UPS delivers the highest level of online double-conversion performance (VFI-SS-111), providing unparalleled protection for critical information and telecommunications systems. Engineered with "Zero Impact Source" technology, this UPS minimises environmental impact and simplifies installation, even in locations with limited power capacity or standby generators. Achieve ultra-low input current distortion (less than 2.5%) and a high power factor of 0.99, ensuring seamless integration and reduced harmonic interference. Note that this unit requires a separate battery cabinet; please contact us for specific runtime details.

Advanced Battery Management and Flexible Operation:

The Multi Sentry UPS features a sophisticated Battery Care System, optimising battery performance and extending lifespan. This system includes temperature compensation, deep discharge protection, and low AC ripple current charging, supporting various battery types (VRLA AGM, GEL, Ni-Cd). Adapt to diverse application needs with flexible operating modes, including online, eco, smart-active, and frequency conversion. The UPS can handle capacitive loads without derating and offers features like Power Share connections and cold-start capabilities for enhanced operational flexibility.

Comprehensive Communication and Low Management Costs:

Benefit from advanced communication options, including a large graphic display for real-time monitoring and control, multiplatform support (PowerShield³), and remote management capabilities (TeleNetGuard). The unit's compact design and high efficiency (up to 96%) minimize energy consumption and operational costs, reducing your total cost of ownership. The Multi Sentry also features inputs for external bypass, synchronisation, and remote emergency power off (REPO), ensuring comprehensive control and reliability.

• One-level recharge to meet the requirements of the most common VRLA AGM batteries
• Two voltage level recharges meeting the IU characteristic
• Restricted charging to reduce electrolyte consumption and extend the life of VRLA batteries
• Temperature compensation: to avoid excessive voltage being applied to the batteries in a high ambient
• Battery test: to detect performance degradation and predict battery failure.
• Deep discharge protection: to prevent the batteries being discharged below a level from which they cannot be recovered (especially when discharged over long periods with very low loads).
• Low AC ripple current: from a high-frequency battery charger, to ensure the batteries are not subjected to this damaging element commonly experienced with some other UPS and power supply designs.
• Wide input voltage range: from a rectifier that can work down to less than 40% of its nominal supply rating (at half load), removing the need to discharge the batteries.
