The autonomy time of a UPS (Uninterruptible Power Supply) system for critical applications such as DCS (Distributed Control System), ESD (Emergency Shutdown System), FGS (Fire and Gas System), and Telecom is determined by the load requirements and battery chemistry. Specifically, the discussion highlights that the autonomy time can range between 1 to 4 hours depending on these factors. Calculating autonomy time involves understanding the total load and the specific characteristics of the battery used, such as Lead-Acid chemistry. For accurate calculations, both reliability and load calculations are essential.
