Precautions when selecting switch mode power supplies
When selecting switch mode power supplies, install devices with a capacity larger than the total of the UPS internal power consumption and internal
power consumption of connected devices to the input side of the UPS. When these conditions are met, usage will be possible with no problems
even if the rated capacity of the UPS is larger than the rated capacity of the switching power supply.
Switch mode power supply capacity > (UPS internal power consumption + Internal power consumption of connected devices)
