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.
