NOTES
All specifications are typical at nominal input, full load, and 25°C unless other-
wise noted Astrodyne products are not authorized or warranteed for use
as critical components in life support systems, equipment used
in hazardous environments, nuclear controls systems, or other
mission-critical applications.
1.Ripple & Noise dependent upon output voltage as specified per par-
ticular model.
2.Minimum load is NOT required for proper operation.
3. Load regulation is measured from 20% ti FL.
4. Line regulation is measured from 90VAC to 264VAC.
5. Preset accuracy measured at nominal load, 115VAC input.
6. O/P noise measured at directly at pins at max. load, with a 0.1uF/ce-
ramic capacitor bypass, pk-pk @ 20MHz bandwidth.
