Runtime can be extended using the Riello BBSDU180-A3 EBM.
Sentinel Dual is the best solution for powering mission critical applications and electro-medical devices requiring maximum power reliability.
Flexibility of installation and use (digital display, user-replaceable battery set), as well as the many communication options available, makes the Sentinel Dual suitable for many different applications from IT to security. Up to 3 Sentinel Duals can be operated in parallel in either capacity or N+1 redundant configuration offering increased reliability for critical system. The Sentinel Dual can be installed as Tower (floor standing) or Rack, ideal for network and server rack applications.
The Sentinel Dual range is available in 4-5-6-8-10 kVA/kW 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 voltage, form and frequency. In addition, the input and output filters significantly increase the load’s immunity to mains disturbances and lightning strikes.
Operating mode 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
Emergency: the UPS can be selected to function only when the mains power supply fails (emergency only mode).
Frequency converter: operation (50 or 60 Hz).
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
Automatic bypass without interruption
Status, measurements and alarms available on standard backlit display
Output sockets protected with resettable thermal switch
Back-feed protection as standard: to prevent energy from being fed back to the network
Manual switching to bypass.
