Testing – Input Voltage Line Regulation
During the previous load tests we set the AC input voltage to 115 VAC. This is an optimum value for most of the power supplies under test. To find out how well each Silencer power supply can handle under and over voltage conditions on the AC mains, I lowered the input voltage to 100 VAC and then raised it to 130 VAC with a Variac (variable autotransformer). Once again we are interested in seeing how well each PSU can maintain the various output voltages as the input line voltage fluctuates +/- 13% (+/- 15 VAC).

Both PSUs produced excellent line regulation with varying input voltage.
