Notes

1. Maximum output deviation is 10% inclusive of remote sense and him. If remote sense is not being used, the +Vsense should be connected to its corresponding+OUTPUT and likewise the sense should be connected to its corresponding -OUTPUT.

2. Triple outputs requires a minimum 10% loading on the output to maintain specified regulation. Operation under no-load condition will not damage these devices, however they may not meet all listed specifications.

3. Load regulation for triple output: Main output (V1): 10 to 100% with 10% to 100% balanced on auxiliaries.

All specifications are typical at nominal input, 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, nuclear controls systems, or other mission-critical applications.
