Electrical Specifications
Specifications are warranted over a temperature range of 0 to 30 °C with default
local sensing. Above 30 °C, the output voltage needs to be derated linearly to zero at
70 °C. Specifications are subject to change without notice.

1. For input voltage variation over the AC input voltage range, with constant rated load.
2. For 0 to 100% load variation, with constant nominal line voltage.
3. Current mode noise is measured from 10% to 100% of rated output voltage, full current.
4. Maximum drift over 60 minutes with constant line, load, and temperature, after 60-minute
warm-up.
5. Maximum drift over 8 hours with constant line, load, and temperature, after 60-minute
warm-up.
6. Change in output per °C change in ambient temperature, with constant line and load.
