Is this what 50% duty cycle means? I (probably naively) thought that meant that the frig runs 30 minutes of each hour and (in my Engel's case according specs.) uses only 4 amps when running.
BTW, when my Engel frig/freezer is running my BMV 600 displays a rate of discharge of -3.5 to -4 amps.
And, again, when it is 90+F inside the van, it runs continuously..........
And only cycles on and off when the van interior is say 55F degrees when camping at the ski resort in the Winter.
[I would love to have a slide out just for the Engel in the Winter, just so I could get it outside where it is cold and not be in the catch 22 of using the Webasto furnace to warm the van interior and then turning up the power on the Engel to compensate.]
Edit: What does the attached pdf performance criteria mean?
I do in fact set my power knob at 5 when it is hot in the van. So at 45C which is 113F my % Running Time is 100% and my Amperage Draw is 3.6Ah/Hr which is about what I have actually experienced. In fact, my experience is that my 100% Running Time starts by 90F.
