Test Procedure:
1. Make sure jumper J4 (PSM) is connected.
2. Connect the electronic load with high voltage module to the output labeled “400 V/ 300
mA”.
3. Connect one of the multimeters in series with the output and load and set it to measure
current.
4. Connect the second multimeter to the output and set it to measure voltage.
5. Connect the oscilloscope with differential probes to the output and set it to measure output
ripple and frequency.
6. Connect the ac power source and power analyzer to the terminals labeled “Input”. Set the
current compliance limit to 3 A.
7. Set the ac power source to 85 Vac / 60 Hz.
8. Set the high voltage electronic load to 300 mA.
9. Turn the AC source on.
10. Wait 10 seconds, and then check the output voltage (V
OUT
) using the corresponding
multimeter. Verify it is within the limits of Table 2.
11. Measure power factor (PF) and input power (P
IN
) using the power analyzer.
12. Measure the peak to peak voltage and frequency of the output ripple using the
oscilloscope.
13. Measure I
OUT
using the corresponding multimeter.
14. Calculate efficiency (η) using the equation:
%100
IN
OUTOUT
P
VI
15. Repeat steps 9-13 with the ac source set to 115 Vac / 60 Hz, 230 Vac / 50 Hz, 265 Vac /
50 Hz. Verify the results are within the limits of Table 2.
16. Turn off the ac source.
17. Since high voltage will be present after the voltage is removed, wait for the dc voltmeter
to show approximately 0 V before continuing.
18. Disconnect the ac source.
19. Disconnect the oscilloscope.
20. Disconnect the electronic load.
21. Disconnect both multimeters.
22. End of test.
