Notes

1. All measurements should be made directly at the terminals of the power supply

2. Isolation for up to 1 minute duration.

3. Preset Accuracy measured at nominal load, 120VAC input.

4. O/P Noise measured directly at the pins/terminals at nominal load, 0.1uF ceramic bypass and 47uF electrolytic, pk-pk @ 20MHz

bandwidth.

All specifications are typical at nominal input, full load, and 25°C unless otherwise noted
