NOTES
1. Make all measurements directly at the pins of the supply
2. Specified for free air convection cooling
3. 115Vin minimum required for full load start up
4. Measured by paralleling 47uF/EC and 0.1uF ceramic capacitors on
the output at a 20MHz band-width
5. The power supply should start up and operate normally into these
capacitive loads within specified input voltage and output current ranges
over the specified operating temperature range and according to Derate.

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.
