Sentinel Dual (Low Power)

Power Range: 1000 - 3000 VA
1:1
High efficiency and density.

Sentinel Dual is the new range of high-density double conversion ONLINE UPS suitable for powering a wide range of devices such as servers, storage systems, VoIP telephony equipment, network and medical systems, and industrial applications.

It is also ideal for powering and protecting Blade Server systems with high input power factor. At only 2U, Sentinel Dual is ideal for 19” rack cabinet installations. Sentinel Dual has a practical, modern design and includes several performance advantages over traditional ON LINE UPS.

The newly-designed inverter is one of the best energy conversion systems on the market, with a 0.9 output power factor and 92% operating efficiency in ON LINE Mode. For business continuity applications requiring long battery runtimes, battery autonomy can be extended up to several hours using ER models fitted with more powerful battery chargers. With energy savings in mind, Sentinel Dual is also fitted with a shut-off button to reduce energy consumption to zero during prolonged periods of inactivity.

HIGHLIGHTS

• Power factor 0.9

• Simplified installation

• Installation versatility

• Reduced running costs

• Runtime expandability

• Low noise level

Sentinel Dual SDU

Power Range: 4 - 10 kVA
1:1 1-3:1

Sentinel Dual is the best solution for powering mission-critical applications and electro-medical devices requiring maximum power reliability.

The Sentinel Dual range is available in 4 kVA and 5-6-8-10 kVA/kW models with ONLINE double conversion technology (VFI): the load is powered continuously by the inverter, which supplies a sinusoidal voltage, filtered and stabilised in terms of voltage, form and frequency.

Reduce your power consumption using ECO and SMART ACTIVE modes. Prioritise your most critical loads with EnergyShare sockets that enable easy load-shedding. Load-controlled fans minimise noise disruption (<48 dBA).

Simplified installation

• Can be installed on the floor (tower version) or in rack mount cabinets (rack version). The display panel can be rotated (using the supplied key);

• Low noise (<48 dBA): can be installed in any environment thanks to its high frequency switching inverter and PWM load-dependent digitally controlled fan;

• External bypass option for maintenance with interruption-free switching;

• Operation guaranteed up to 40 °C (the components are designed for high temperatures and are thus subject to less stress at normal temperatures);

• Built-in IEC output sockets with thermal protection.

Operating mode selection

Functions can be programmed via software or manually via the front display panel.

• ONLINE: efficiency up to 95%;

• ECO Mode: to increase efficiency (up to 98%), allows for the selection of LINE INTERACTIVE technology (VI) to power low-priority loads from the mains supply;

• SMART ACTIVE: The UPS automatically decides upon the operating mode (VI or VFI) based on the quality of the mains power supply;

• STANDBY OFF: The UPS can be selected to function only when the mains power supply fails (emergency-only mode);

• Frequency Converter operation (50 or 60 Hz).

High-quality output voltage

• Even with non-linear loads (IT loads with a crest factor of up to 3:1);

• High short circuit current on bypass;

• High overload capacity: 150% by inverter (even with mains failure);

• Filtered, stabilised and reliable voltage (double conversion ON LINE technology (VFI compliant with EN62040-3), with filters for the suppression of atmospheric disturbances;

• Power factor correction: UPS input power factor close to 1 and sinusoidal current uptake.

Other features

• Selectable output voltage (220/230/240 V);

• Dual input supplies configuration (SDU 10000 DI and SDU 10000 DI ER);

• Auto-restart when mains power is restored (programmable via software);

• Bypass on: When the machine is switched off, it automatically goes into bypass and battery charge mode;

• Minimum load switch-off;

• Low battery warning;

• Start-up delay;

• Total microprocessor and DSP control;

• Automatic bypass without interruption;

• Use of custom power modules;

• Status, measurements and alarms are available on standard backlit display;

• UPS digital updating (flash memory upgradeable);

• Output sockets protected with resettable thermal switch;

• Back-feed protection standard: to prevent energy from being fed back to the network;

• Manual switching to bypass.
