Spiff, a few years ago I converted my base model 3 speed Fantastic Fan from the simple resistor network it came with, to an off-the-shelf PWM variable speed controller.
I didnt like all the wasted energy (and heat) being consumed by the resistors, I don't remember the exact current on low, but it was about an amp or maybe a bit more.
With the PWM motor speed controller, I could vary the speed down to really low, and the current draw was somewhere around .5 amps IIRC.
Plus it gave me variable speeds, which was nice.
The only problem in my case was that the PWM board had no RFI shielding and my on-board ham radios tended to interfere with it when transmitting, and the reverse was also true: The PWM board spit out EM interference up and down the VHF and UHF bands, and my antenna is pretty close to it, so it was able to actually desense the receiver when operating.
Normally, I'm not using both at the same time, but it was aggravating until I figured things out.
I wonder if the MaxxAir electronics are shielded from all of this? Might be worth me looking into.
