The most wattage that the power supply would draw would be 150 watts (15 volts at 10 amps). However, for R/C car stick packs it would be more realistic to see 40 to 60 watts.
We were way off trying to determine power consumption using an Ohm's law circle. We went back to our RS Basic Electronics book and are now using the power circle. Thanks, Tim.
Does the 989 SuperBrain have any specific requirement for type of 115vac input? Specifically, is Modified Sine Wave/Semi-Sine Wave acceptable, or does the 989 require [Full] Sine Wave for an input waveform to the power supply? Does it matter?
Also, will the 989 trickle charge a full size AGM (Absorbed Glass Mat) battery?
We are still gathering data on inverter vs. gas generator use in the pits. We really want to make a case for a 1500W inverter powered by an auxillary AGM battery instead of a 1000W gas generator. However, the Honda EU1000 generator we are looking at features full sine wave output. That makes it a better match for the 989?
