standby electric supply systems
Standby electric supply systems are distinguished between uninterruptible power supply stations which absorb the immediate supply of consumers and emergency backup generators, which ensure long-term supply after reaction time.
Generally, they serve as bridging for supply interruption and secure supply of peripheric consumers. Here the application areas are life-sustaining measures in hospitals, EDP systems, security-relevant systems as fire alarm-, burglar alarm-, and electroacoustic systems and emergency lightning.
Consideration of availability, bridging time and needed power are main criteria of standby electric supply systems.
