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 25DegC unless

otherwise 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. Ripple and noise dependent upon output voltage as specified per

particular model.

3. Isolation for up to 1 minute duration.

4. Specified for free air convection cooling.

5. Minimum load is not required for proper operation.

6. Load Regulation is measured from 5% to Full Load.

7. Line Regulation measured from High Line to Low Line.

8. Preset Accuracy measured at nominal load, 120VAC input.

9. O/P Noise measured directly at the pins/terminals at nominal load,

0.1uF bypass and 47uF electrolytic, pk-pk @ 20MHz bandwidth.

10. 100% Production Tested
