Riello UPS Sentinel 4kVA SDU 4000

BATTERY OPTIMISATION

The wide input voltage range and a high
hold-up time minimise battery usage and
increase efficiency and battery life; for
smaller power breaks, energy is drawn
from a group of appropriately-sized
capacitors.

HIGH BATTERY RELIABILITY
• Automatic and manual battery test

EMERGENCY FUNCTION
This configuration ensures the operation
of those emergency systems that require
continuous, reliable and long-lasting
power supply in the event of a mains
power failure, such as emergency lighting,
fire detection/extinguishing systems and
alarms. When the mains power supply
fails, the inverter begins powering the
loads with a progressive start up (Soft
Start) in order to prevent overload.

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
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).

EnergyShare
10 A configurable IEC output sockets allow for runtime optimisation by programming the switching off of low priority loads on mains failure; alternatively, emergency loads that are normally not powered when mains is
present can be activated.
