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.

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
