What is the wdbacw0030hbk-01 power requirement? 12v how many amps?

I mix the power supply with others I have, and I don’t know which one to use. I find it irritating, that the device, manual or box does not say it. I honestly don’t know how you can approve a product for sale without this.

I have read that it needs 12v, but how many minimum amps?

Regards

should be 1.5-2 amps
