1. Load regulation is measured from 60% to full load and from 60% to 20% load
(60% ±40% full load).
2. Measured at the output connector with a 0.1 µF ceramic capacitor and a 10 µF
electrolytic capacitor.
3. Peak load lasting <30 s with a maximum duty cycle of 10%, average output
power not to exceed nominal.
4. Average of efficiencies measured at 25%, 50%, 75% & 100% load and
230 VAC input
5. Typical trip point.
6. Other voltages between 5 V & 30 V are available on request, contact sales for
