PART NUMBER: VCD6 series

NOTES:

1. measured from high line to low line

2. measured from full load to1/4 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

desired fuse size.

4. alternative pin configuration suffix “S”
