9. To prevent reverse input voltage protection(Ex.)
This product is a non-isolated type DC-DC converter that
steps-down from (+) to (+).
If the input voltage reversed is connected by mistake, it will
be damaged.
If there is a possibility of reverse connection, please add
a protection as shown in the right figure. The right figure is
an example using fuse and diode.
10. Over-Voltage Protection Diagram (Ex.)
This product does not have a built-in over-voltage protection.
If the switching element in this converter is damaged in short
mode, DC input voltage will go out as output.
To avoid damage at over-voltage mode, in advance,
please add the input interrupting circuit as the right figure.
Note 1. When it is damaged at over-voltage mode,
Note 2. When having ON/OFF function on the supplying
Note 3. Be sure that the DC power supply on the supplying
ON/OFF control will not operate.
