PRECAUTIONS
• Parallel operation to increase output current is not possible.
• Input fuse
A 0.15A fuse should be connected to the input.
• Wiring between the input power supply and the converter should
be short so as to reduce impedance as much as possible. How-
ever, if the input line impedance is high, installation of an input
capacitor is recommended.
• Install the components according to the diagram shown below.
