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.
