• Manufacturer Part Number: bsv-1.5s12r0h
• Description: Pol Dc-dc Converter
• Manufacturer: XP Power Limited

This product does not have a built-in over-voltage protection.
If the switching element in this converter is damaged in short
mode, input voltage (+Vin) will go out as output.
However, to avoid damage at over-voltage mode, in advance,
adding a circuit to intercept the supplying power circuit can
be recommended.
Note 1. When it is damaged at over-voltage mode, ON/ OFF control
Note 2. When there is an ON/ OFF function on the supplying power
Note 3. Be sure that the DC power supply on the supplying side has
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.
