FLEXIBILITY OF INSTALLATION AND USE
The UPS can be installed as a floor standing tower or 19″ rackmount UPS.
The front panel digital display can be pulled out (using the keys provided) and rotated to suit the installation format. Low noise level (<40dBA) thanks to the digitally PWM controlled ventilation system which is load and temperature dependent, and the use of an inverter with a high switching frequency (>20kHZ, above the audible range). DIALOG Dual is suitable for installation in any populated environment.
Operating modes:
- On-line (VFI): the inverter powers the load continuously ·
- Economy: the UPS mimics a Line Interactive (VI) UPS supporting the load from its battery supply when the mains fails or fluctuates wildly ·
- Smart Active: the UPS selects automatically whether to operate in On-line (VFI) or Line Interactive (VI) mode depending on the stability of the mains supply.
- Emergency: the UPS only supports the load with its batteries when the mains fails – suitable for emergency lighting · Frequency conversion 50 or 60Hz ·
- Output voltage selection: 220-230-240Vac single-phase or 380-400-415Vac three-phas
QUALITY OF POWER SUPPLY
- Filtered, stable and reliable voltage – On Line double conversion (VFI) technology in accordance with EN50091-3, a with EMI filters ·
- Guaranteed output quality even with typical distorting IT loads with crest factors of 3:1 ·
- Low impact on the mains supply as the UPS has an input power factory near to 1, with a sinusoidal input current
ADVANCED DIAGNOSTICS
- Status, measurements, and alarms available on the standard backlit display
- UPS can be updated digitally (flash upgradeable)
OPTIMAL BATTERY MANAGEMENT
- Reliable battery performance (automatic and manual battery tests) ·
- Prolonged battery life due to the unique Low Ripple Current Discharge (LRCD)
- ‘Hot-swap’ user replaceable batteries
- Extendible back-up time using additional Battery Extension Packs or Trays Increased ride through (without batteries) on mains breaks up to 40ms and for fluctuations ranging from 84 to 276Vac
ENHANCED ELECTRICAL PERFORMANCE
- Input protected by resettable thermally activated switch
- Back-feed protection: to avoid energy being fed back into the mains should a fault occur
- Increased short circuit current on the by-pass
Increased overload capacity: 150% on inverter even without a mains supply present - Performance guaranteed in temperatures up to 40°C short term
- Manual switch to by-pass
- Two-year warranty
Sentinel Tower
Sentinel Tower is the ideal solution for protecting mission critical systems such as safety devices, telecommunications equipment but also IT systems to ensure maximum power reliability.
Sentinel Tower is designed and built using state-of-the-art technology and components to provide maximum protection to the powered loads with no impact on downstream systems and optimised energy savings.

The series includes 5-6 kVA/kW single/single-phase and 8-10 kVA/kW single/three-phase input single-phase output models with on-line double conversion technology (VFI): the load is powered continuously by the inverter which supplies a sinusoidal voltage, filtered and stabilised in terms of form and frequency. Input and output filters provide significant further immunity from mains disturbances and lightning strikes.
In terms of technology and performance, Sentinel Tower is one of the best UPS available on the market today: three level inventer to achieve 95% efficiency, output power factor 1 to Increase in efficiency of system and devices and reduce power system losses.
Features
- Total microprocessor and DSP control
- Unity power factor means you get a real output power (W)
- Economy Mode offers up to 98% efficiency, which allows for the selection of Line Interactive technology (VI) to power low priority loads from the mains supply
- Emergency: the UPS can be selected to function only when the mains power supply fails (emergency only mode)
- High overload capacity: 150% by inverter (even with mains failure)
- Automatic and manual battery test
- Compatible with Riello Connect remote monitoring
