PRECAUTIONS
• These converters can not be used in parallel to increase output
current.
• Since the converter is entirely shielded by a metal case, care
should be taken to isolate the case from the surrounding
components and wiring pattern.
• A fuse should be connected to the input with a current rating 3 to
8 times that of the rated(normal) input current.
