Frequently asked questions
Can I power a 12V LED strip with this adjustable transformer?
Yes, set the voltage to 12V using the potentiometer and check the LCD display. Ensure that the LED strip consumes a maximum of 2A (24W at 12V).
How do I know what voltage to choose for my device?
Consult the device's label or specifications — the digital display shows the set voltage in real-time, and adjustment is made gradually to the correct value.
What happens if I exceed the maximum current of 2A?
The power supply has overload protection and will automatically shut off to prevent damage — do not connect devices that consume over 2000mA.
