* 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.
Notes:
1. All measurements should be made directly at the terminals of the
power supply
2. 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 reugulation will be higher.
3. Load Regulation measured from 20% to full load. All other outputs at
nominal load.
4. Output noise measured directky at pins at nomimnal load with 0.1uF
and 10uF capacitors, pk-pk @ 20MHz bandwidth.
