How did you check the output?
It states on the label that the output is 28 to 32V at 300mA with a power factor of 0.7%.
Nice picture of a DMM but I repeat, how did you check the output? Was the output connected to anything? If so, what?
Sir With load output is 48voltage without load approx 140voltageNice picture of a DMM but I repeat, how did you check the output? Was the output connected to anything? If so, what?
