HLK-2M05 AC-DC 220V to 5V
If you are looking for a simple solution to power a 5V circuit directly from 22V AC, this module is your solution. It has a built-in step-down transformer and bridge rectifier to step 22V AC down to 5 and then convert the AC to DC. This is ideal to use on modules that require 5V, but does not require a lot of current to operate.
How to set it up:
Setting up this module is extremely simple. You simply connect the 220V AC to the two AC pins on the bottom of the module, and then use the positive and negative pins as the 5V output.
|Output Current (Max)||0.4A|
|Isolated Or Voltage Regulation||Isolated Regulated|
|Feature||Overcurrent Protection;Short-Circuit Protection|
