Hi all,
im working on the camping chair rebuild and i have came acroos some issues with the electronics im not sure if there a problem on my part or on the parts side.
firstly i hooked up the fans and smoke detector tothe psu and to a 12v 500ma power supply everythink worked fine the fans were running at half speed due to the fans both trying to use 500ma each so i then unhooked this and attached the peltier to the psu... this is where the problems started.
firstly the led on the psu was flashnig and there was a humming comming from the psu i hooked a temp monitor up to the cooler and i noticed it wasnt cooling i then tested the voltages the smoke detector was 5v and the cooler was only at 9.8v i had believed that the peltier was 12v.
so i hooker the coller up to the 12v supply and hey presto the cooler dropped from 20 celcius to 15 in about a minute this was a dry run with the probe on the heat sink then problems again the power supply failed so i am guessing that the peltier uses more than 500ma?
anybody have any ideas?
and if ben happens to read this i would greatly apreciate the volts of the peltier as i cant read the peltier because someone epoxied it inplace
