[NSRCA-discussion] NEW IOTA 55amp POWER CONVERTERS

Mon Mar 6 21:12:51 AKST 2006

Thanks Chad,
I'm at least a little less confused than before. If the Iota is a 740 watt 
power supply, does that mean that that's the most it'll ever be pulling from 
the Honda? The Honda is rated at 900 continuous, 1000 surge. If I'm 
understanding you, one Iota 55 amp supply will power two 1010's which in 
turn will charge four 5300's at the same time. You said that it'd be close. 
What's taking the beating, the power supply or the generator? Your patience 
is appreciated!

Verne
