I know what you mean, the most accurate test would be if the test voltage was coming from the mains. But, The IEC standard has this requirement, and i cant deviate from it.
Well you see, The UUT is a battery charger. I have to supply 115V at 60Hz, and maitain this test voltage, because i want to check the efficiency of the charger. So the application requires me to follow this condition. I am not allowed to measure efficiency at another test voltage with...
No, This is one of the measurement condition for testing Battery chargers in a standard. I have everything to perform the test except for this constant powersupply. The wall cannot give less than 2% THD, so i need to get a power supply, or generator that will give that.
Hi
Can somebody help me with selecting a powersupply that will provide less than 2%THD upto the 13th harmonic, and provide a constant voltage at 115V 60Hz. Any help will be greatly appreciated.
Thanks
