Sentinel Dual SDU


Technical sheet : Sentinel Dual SDU


Simplified installation

  • Possibility of installation on the ground (tower version) or in a cabinet (rack version). It is possible to turn the display panel (using the key supplied);

  • Low noise level (<48 dBA): for installation in any environment, thanks to its inverter with high switching frequency and PWM fan with digital control depending on the applied load;

  • Connection possible via external maintenance bypass with continuous switching;

  • Guaranteed characteristics up to 40 ° C (components are designed for high temperatures and therefore undergo less stress in the presence of ordinary temperatures);

  • Integrated IEC-type output sockets with thermal protection.

Selecting the operating mode

The functions are programmable from software or manually configurable using the front display.

  • ON LINE: efficiency up to 95%;

  • ECO mode: to increase efficiency (up to 98%), it allows selection of LINE INTERACTIVE (VI) technology to supply insensitive loads from the network;

  • SMART ACTIVE: the UPS decides, independently, of the operating mode (VI or VFI) according to the quality of the mains power supply.

  • STANDBY OFF: the UPS can be selected to operate only in the event of a network failure (emergency mode only);

  • Frequency converter operation (50 or 60 Hz).

High quality of the output voltage

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

  • High short-circuit current on bypass; High overload capacity: 150% per inverter (even in the event of a grid failure);

  • Filtered, stabilized and reliable voltage: ON LINE double conversion technology (PFD in accordance with EN62040-3) with filters for the suppression of atmospheric disturbances;

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

  • Batteries can be replaced by the user, without the need to stop the device and without interrupting the charge (Hot Swap);

  • Unlimited extendable autonomy using battery cabinets;

  • The batteries do not intervene in the event of a mains failure <20 ms (high waiting time) or if the input power supply is between 184 V and 276 V.

Other characteristics

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

  • Power supply configuration of two input devices (SDU 10000 DI and SDU 10000 DI ER);

  • Auto-restart on restoration of the mains (programmable by software);

  • Bypass On: when the machine is off, it is automatically prepared for operation by the bypass and with the batteries charged;

  • Shutdown for minimum load;

  • Notice of total battery discharge;

  • Start-up delay; T

  • otal control by microprocessors and DSP;

  • Automatic bypass without interruption;

  • Use of customized power modules;

  • States, measurements, alarms available on standard backlit screen;

  • UPS digital update (flash memory upgradeable);

  • Protection of output sockets by resettable thermal switch;

  • Standard power return protection: to prevent energy returns to the network;

  • Manual switching to bypass.
