Does my garden 250 watt AC/DC transformer consume 250 watts when I only have 50 watts of DC LED lighting? Answered
So the question is: Does an AC/DC transformer consume its max wattage even when it's not maxed out on the DC side? I have a 250 watt transformer that steps down to 12V for low voltage garden lighting. Is it always drawing 250 watts? Added up, I have about 50 watts of LED low voltage fixtures.
Back in my military days, when we were in Europe, we had these 300, 500, and 1000 watt transformers to step Europe 240V down to US 120V, and we were always told those transformers drew their max capacity even if a small radio was plugged into it. I argued it prolly didn't because of the conservation of energy thing.
I can always put a kill-a-watt meter on it too I guess.
Thanks in advance!
