High recharge current and Battery Care System Proper battery care is critical to ensuring correct CSS operation in emergency conditions. The Riello UPS battery care system consists of a series of features and capabilities designed to obtain the best performance, extend operating life and satisfy the recharge times imposed by the standard. The Riello UPS CSS Sentinel Tower range is designed in compliance with standard EN 50171 and ensures high current levels are available for the batteries, allowing recharge of up to 80% of full autonomy within 12 hours. Riello UPS CSS Sentinel Tower are suitable for use with hermetically sealed lead-acid (VRLA), AGM and GEL batteries and Open Vent and Nickel batteries. Different charging methods are available depending on the battery type. The recharge voltage compensation function based on temperature prevents excessive battery charges and overheating. The deep discharge protection prevents reduced battery performance and battery damage.

High overload capacity As required by standard EN 50171, the Riello UPS CSS Sentinel Tower range is designed and sized to support continuous overloads (with no time limits) of up to 120% of nominal load.

Protection against battery inversion Mandatory in line with standard EN 50171, protection against battery inversion ensures the safety of those carrying out maintenance operations on the devices and at the same time prevents damage to the system in the event that the batteries are inadvertently connected with the wrong polarity.
