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. Dimensions in inches (mm) Specifications subject to change. 43
