
Typical @ T
A = +25°C under nominal line voltage and full-load conditions unless otherwise noted.
For testing and specifi cation purposes, “full load” is defi ned as 2.75A on the primary +5V output and
±250/200mA on the auxiliary ±12/15V outputs. This corresponds to a total output power of 19.75W.

Ripple/Noise (R/N) measured over a 20MHz bandwidth.

For the +5V output, listed spec applies over the 10% to 100% load range. For the ±12/15V outputs,
listed spec applies for balanced loads over the 20% to 100% load range.

Nominal line voltage, no-load/full-load conditions.
