Just added 240 volts to the shack. I am wondering if rewiring my Centaur for 240 volts would change or improve performance? If so I would love an explanation of the theory behind any improvement or e

The only reason, seems to me, is that on 240 V, you will draw half the current, and you will experience less voltage droop and I2R power loss. This may give you a little extra power on peaks and a li

In a 120/240 volt single phase service, a competent electrician tries to balance the loads so that the two hot service entrance conductors will carry equal current. If a 240 volt circuit is added, th

Hi Tim, this is Josh in Alabama, N4VB. I made several changes to my Centaur. 1.. change out noisy fan... 2... install new 572B's.... 3..Move over to 240V. Now it runs much more quiet, cool and more p

Funny -- up here in the blue states, we're billed by the kilowatt-hour. 10 amps at 240 V cost the same as 20 amps at 120 V. I don't think they're smart enough to charge for unbalanced current in the

Half the current times twice the voltage equals the same power. Maybe if 240 is slightly more effecient you might save a little. Just nitpicking :-). John N1JM Costs less on your electric bill too. P

Josh, Can you please provide the details on the quieter fan? I'd also be interested in the results you've obtained with the 572s. I've seen conflicting stories regarding the benefits and am still run

Not too familiar with the Centaur, but take a look at the plate voltage on standby and then key down. On 110, it will probably drop 10% or so. The drop WILL be less when you wire for 240. Now, if tha

Hi Joel. This is a HOT thread. Several have ask about the Centaur fan replacement. The one I used is the Mouser part #5912-4800X. 57.1 CFM @ 1750 RPM. (www.mouser.com). I think the key is 1750 RPM, m

Hi Jason. Never had a 425, so can't add anything. BUT, the Mouser web is very detail. You may have to take the old fan out and measure it for a match. Wish I had more info. 73 Josh __________________
