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. However, if the input line impedance is high, installation of an input
capacitor is recommended.
• Install the components according to the diagram shown below.
