The SENTINEL PRO has evolved from the highly successful Dialog UPS series. The UPS has a unique, modern design and improved electrical characteristics, representing a benchmark product from the Riello UPS research and development team. SENTINEL PRO uses On-line double conversion technology, resulting in the highest levels of reliability and maximum protection for critical loads such as servers, and IT and Voice/Data applications. For business continuity applications requiring long battery runtimes, runtimes up to several hours are possible, using ER models fitted with more powerful battery chargers, and battery extension packs. The front mimic panel has been entirely redesigned, adding an LCD display that shows the input and output voltages, and battery readings in addition to UPS operating status information. The inverter and the microprocessor control stage has been completely redesigned to provide increased efficiency and greater configuration options.
- Filtered, stabilised and reliable voltage: double conversion On-line technology (VFI compliant with IEC 62040-3) standard with filters for the suppression of atmospheric disturbances.
- High overload capability (up to 150%)
- Programmable Auto-restart when mains is restored
- Battery start-up (cold start)
- Power factor correction (UPS input power factor, close to 1)
- Wide input voltage range (from 140V to 276V) without battery intervention.
- Runtime extension to several hours
- Fully configurable using UPS Tools configuration software
- Highly reliable batteries (automatic and manually activated battery test)
- High level of UPS reliability (total microprocessor control)
- Low impact on the mains (sinusoidal absorption)
- Input protection with resettable fuse.
Ordered on Request, usually ships in 10-14 days.
