Industrial factories, substations and distribution rooms generally adopt 12V100Ah lead-acid batteries as DC screen backup power supplies to provide emergency power for industrial automatic control systems, relay protection devices and instrument monitoring equipment. Industrial production has extremely high requirements for power supply stability, and sudden power outages may easily cause equipment shutdown, data loss and production accidents. With fast response speed, the battery can take over power supply instantly to ensure the continuous operation of industrial monitoring and protection equipment, reserving sufficient time for equipment maintenance and fault handling. Featuring impact resistance and high stability, it adapts to complex industrial working conditions and serves as an important backup support for the safe operation of industrial power systems.
