Product review & video
in this video I will give you a basic understanding of the step-down power transformer this will include the proper placement of the fuse and fuse holder how to measure the secondary voltages with a digital multimeter and how to test the transformer using your own meter so let's get started all of these transformers will do exactly the same thing as a transformer gets bigger the output current gets larger for this small transformer it has a 25 volt center tap winding and it can only deliver up to 0.3 amps the center tap is nothing more than a wire soldered right to the very middle of the secondary winding this transformers a little weed bit bigger and you'll notice it's going to be able to have a maximum current draw of 0.5 amps the next one is 1 amp and you can see it's getting a little wee bit bigger in this very last one it's going to beat a 2 amp transformer all of them will deliver
