• Multimeter
• Potentiometer (if needed)

Frequently asked questions

Can I use this power supply with a device requiring a voltage different from 12V?
Check the datasheet to see if the power supply supports voltage conversion. Otherwise, use a voltage converter.

How long can this power supply operate before the battery runs out?
This power supply does not have a battery. It is an adapter that converts electrical voltage from 230V to 12V. It does not have a battery.

Do I need a fuse?
Check the datasheet of the device to be powered. If necessary, connect a fuse between the power supply and the device.

Can there be a problem if I connect two devices at the same time?
Check the total current required by the devices. If it exceeds the maximum current of the power supply, it may not work properly.
