Notes:
Note5: For repeat Hi-Pot testing, reduce the time and/or the test voltage
Note6: To protect the converter under all fault conditions, an input fuse is required. Quick-fuses should be rated at 2x-3x the
nominal input current, time -delay fuses at 1.5x the nominal input current
DC-DC ON: Open or high impedance
DC-DC OFF: V
