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, auxiliary
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.
* 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 b, full load, and 25°C unless otherwise noted
Astrodyne products are not authorized or warranteed for use as critical components in life support systems, equipment used in hazardous environments, nub controls systems, or other mission-critical applications.
