Note: To protect the converter under all fault conditions, an input fuse is required. Quick-blow fusesshould be rated at 2x-3x the normal input current, time-delay fuses at 1.5x the normal input current.

Notes
Note 1:
Note 2:

Maximum capacitive load is defined as the capacitive load that will allow start up in under 1 second without damage to the converter
The RS3 series requires a minimum of 10% load on the output to maintain specified regulation. Operating under no-load conditions
will not damage these devices; however, they may not meet all listed specifications.
