NOTE:
1. Measured from High Line to Low Line.
2. Measured from Full Load to 1/4 Full Load.
3. Determine the correct fuse size by calculating the
maximum DC current drain at low line input,
maximum load and then adding 20 to 25% to get
the desired fuse size.
4. A 10% minimum load is required on dual and triple
output models for rated performance.
