Working mode of APC Schneider UPS power supply in machine room

The APC Schneider UPS power supply for the core machine room is important load power supply, which can not be ignored. In recent years, APC Schneider UPS power supply system has been built for network data room in all walks of life to ensure the stable and reliable operation of power in the room and the safety and accuracy of data. For network operation and maintenance managers, it is more and more important to master the operation and maintenance management method of APC Schneider UPS power supply.

The APC Schneider UPS power supply for the core machine room is important load power supply, which can not be ignored. In recent years, APC Schneider UPS power supply system has been built for network data room in all walks of life to ensure the stable and reliable operation of power in the room and the safety and accuracy of data. For network operation and maintenance managers, it is more and more important to master the operation and maintenance management method of APC Schneider UPS power supply. Here's how:

1. Normal working mode (working power supply): when the working power supply is normally input, the rectifier converts the alternating current to the direct current, supplies it to the inverter, and then outputs it to the load.

2. Standby mode (DC power supply): when the working power supply is abnormal, the DC power supply can quickly replace the rectifier to provide DC input for the inverter. Therefore, the output AC converted by the inverter will not be interrupted. Therefore, the load connected to the output can be well protected.

3. Standby power mode (bypass power supply): when the frequency converter is in an abnormal state, such as high temperature, short circuit, abnormal output voltage or overload beyond the receiving range of the frequency converter, the frequency converter will automatically stop working to prevent damage. If the bypass power supply is normal at this time, the static switch will switch to the standby power output of the load.

4. Maintenance bypass mode: when the APC Schneider UPS power supply equipment in the machine room needs daily maintenance or needs to replace the power supply of the power plant and the output cannot be interrupted, the user can stop the frequency converter and then turn off the maintenance bypass air switch. Then disconnect the rectifier and standby bypass air switch. In this way, the AC power supply to the load will not be interrupted during the switching process, but there is no AC or DC power supply in UPS except for the output transformer, which can effectively ensure the safety of maintenance personnel.
