Dolphin Ampmasters

thats what I was thinking Bryan, 77 watts seams like a awfull lot of power to be disapated as heat in a power cord.

That means your power cord is consuming 0.64amps Darren.. does that make sence to you? I would think it would be a little hard to hold on to the cord for more than a fraction of a second due to the heat that is being throwen off by the cord if this is the case.

if the dolphin pumps is as I remember it should be a centrifical pump..am I right? and are you using it to push water back up to the main tank? if so I would think that the ratins dolphin used are for 0 head. so if you had the pump at the top of your tank and drew strait out and put it strait back it you would probably get there numbers.. the more head ou put on it the harder the moror has to work.. and the more power it draws. the electric motors used in that type of a pump are a constan speed type motor so as increased head pressur caused the impeller to slow down the motor will draw more curent to bring the speed back up to its rated rpm. I will go through my notes and get you the proper terms on this type of speed controle if you want but basicly thats how it works.
