1. Specifications indicate typical performance at 25° C +/- 5° C, nominal line input of 120 VAC.
2. For input voltage variation over the AC input voltage range, with constant rated load.
3. For 0-100% load variation, with constant nominal line voltage.
4. Maximum drift over 8 hours with constant line, load and temperature, after 60 minutes warm-up.
5. Change in output per ° C change in ambient temperature, with constant line and load.
6. Apply accuracy specifications according to the following voltage program accuracy example:
Set a model 15-20 power supply to 10 volts. The expected result will be within the range of
10 volts +/- 60 mV +/- 0.1% of the set voltage of 10 volts.
