Width is 50mm (75mm with mounting tabs)
Height is 40mm
Depth is 40mm
Input is 110V/220V. Output is 24V + 24V.
You get 48V by using the two YELLOW wires.
If you need 24V you can use one YELLOW 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.
