Uninterruptible power supply

In automation, a high-availability 24 V power supply avoids costly machine downtimes machine downtimes caused by mains interruptions. For short-term interruptions in the range of several 100 ms, it is recommended to use a maintenancefree buffer module with an application-dependent service life of up to ten years. Longer mains failures are bridged by our uninterruptible power supply unit in conjunction with a battery module. Depending on requirements, these modules supply energy up to 40 A for 30 minutes or 1 A for 30 hours. Battery life is guaranteed by the temperature-compensated charging characteristic. Weidmüller‘s uninterruptible power supplies reliably protect 24 V DC consumers from power failures and voltage drops, such as those caused by mains faults, which can affect system availability. Together with the associated battery module and the power supply unit, the UPS control unit forms a complete DC UPS system with backup times in the range of minutes to hours. The total load is divided into non-safe and safe loads.
