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. Measured at the rear panel output connector unless stated otherwise.

4. Maximum drift over 8 hours with constant line, load and temperature, after 30 minute warm-up.

5. Change in output per ° C change in ambient temperature, with constant line and load.

6. Line drop is subtracted from total voltage available at supply output.

7. Typical efficiency at 115 VAC input and rated output power.

8. Apply accuracy specifications according to the following voltage program accuracy example:
    Set a model 20-130 power supply to 10 volts. The expected result will be within the range of 10 volts +/- 75 mV +/-
    0.12% of the set voltage of 10 volts.
