The power supply is isolated industrial power modules, with a temperature protection, over current and short circuit full protection, high and low voltage isolation, AC85 ~ 265V wide voltage AC and DC input, 431 precision regulator DC 12V output, ultra-small size, high reliability, high cost performance.
AC-DC 12V 400mA 4.5W Precision Buck Converter AC 220V to DC 12V Step Down Transformer Power Supply Module Step Down Module Condition: New With temperature protection, over current protection and short circuit protection, high and low voltage isolation, AC85 ~ 265 v wide voltage input.
Here’s an easy way to power your Arduino! The AC-DC 220v to 12V 4.5W Isolated Switch Power Supply Module is a buck step down 220V to 12V power module, meaning you can connect one side to a power outlet and one side to a 12V microcontroller board. It also provides all the necessary protection for AC power handling so no need to worry about burning your devices.
