1. For input voltage variation over the AC input voltage range, with constant rated load.
2. For 0-100% load variation, with constant nominal line voltage. Measured at the rear panel output connector unless
stated otherwise.
3. Maximum drift over 8 hours with constant line, load, and temperature, after 30-minute warm-up.
4. Change in output per °C change in ambient temperature, with constant line and load.
5. Line drop is subtracted from total voltage available at supply output.
6. Typical efficiency at 115 Vac input and rated output power.
