Hi Dave, well I just did a little re-test to rejog my memory.
My Kendrick model VI (most basic unit) cycles 40% 'on' when set to 'Min', up to 100% 'on' when set at 'High', so I guess when I run at 'Medium' it is around 60% 'on' cycle. When I run my LXD75 at idle, there is barely any amp draw (maybe 0.1 to 0.2 amp), but with fast dual-axis slewing the amp draw is 0.5. When the dew strap cycles 'on', the total amp draw is 1.5 amps, so my meagre 3 inch dew strap pulls a full amp when its heating.
Assuming that 4 separate similar size dew straps (for your application) will each draw 1 amp, would I be correct to say that is approx. 4 amps alone (for ~60% of the time) for anti-dew, using the basic Kendrick unit. Hey, your 80-100AH source is not at all ridiculous when you look at the numbers!
I guess the higher model controllers with temp feedback etc., individual channel control etc. is where the power-management efficiency comes into play. You get what you pay for, but the most basic Kendrick unit with 4 straps is one possible option. The controller and strap, new, cost me $260 from Bintel and it's well worth it my book. Fox
