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:
