NOTES
1. Ripple and Noise depend upon output voltage as specified per par-
ticular model.
2. Short Curcuit Protection is self-recovering when overcurrent condition
is removed.
3.Isolation for up to 1 minute duration.
4. Specified for free-air convection cooling.
5. Minimum load is NOT required for proper operation. However, auxil-
iary outputs should be reduced as a function of primary output minimum
load or load regulation will be higher.
6. Load regulation measured from 20% to full load.
7. Line regulation measured from 90VAC to 264VAC.
8. Preset accuracy measured at nominal load, 120VAC input.
9. O/P noise measured directly at pins/terminals at nom. load, 0.1uF
bypass, pk-pk @20MHz bandwidth.
10.Cross Reg-Duals: Measured at nom. load with the other output varied
between 60% and 100% inom.
* 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.
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.
