There are three kinds of ground in ordinary UPS power supply (of course, there is also one kind of ground), the common control part and the driving part are common ground, and the driving signal output to the power part is a floating ground. Partial power input and output voltage are relatively high, so corresponding measures should be taken when testing with an oscilloscope to avoid adverse results to the equipment.
What problems should be paid attention to in the maintenance of UPS power supply?
Pay attention to the location of the frequent faults of the same model of UPS power supply.
