Sentinel Dual SDU

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 key supplied);
• 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.

• ON LINE: efficiency up to 95%;
• ECO Mode: to increase efficiency (up to 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 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.
