CAUTION: This converter is not internally fused. An input line fuse must be used in application.
Recommend a fast-acting fuse with maximum rating of 25A on system board. Refer to the fuse
manufacture’s datasheet for further information.
Notes:
1. This converter has internal C-L-C (23.5uF) filter.
2. All specifications are typical at 25
°C unless otherwise stated.
