Brand new 24V 8A 8000 mA center tap AC transformer.
Input is 110V/220V.  Output is 12V + 12V.
You get 24V by using the two blue wires.
If you need 12V you can use one blue and one black wire.

This is an AC transformer and the output is AC also.
If you need DC you need a power supply not a transformer.
If you try to measure the output using the DC setting in your meter it would not give you a voltage.
You need to set it to AC in order to measure the output voltage.
