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.
* These are stress ratings. Exposure of the devices to any of these conditions
may adversely affect long term reliability. Proper operation under conditions
other than the standard operating conditions is neither warranteed nor implied.
