(It is used in the computer core room. In order to ensure the continuous operation of the computer and give full play to the role of the UPS, three-way high-voltage first-class power supply is used for the power supply, and one way is used as a backup to ensure that the computer can run continuously (because the battery can generally only maintain 10~ 20 minutes, in case of a prolonged power outage, the computer cannot run). To ensure three-way power supply, it is best to add connections between the three-way high-voltage power supplies to minimize power outages. When doing load distribution on the low-voltage side, the UPS power supply and bypass power supply and other power equipment do not use the same low-voltage power distribution cabinet.)
