I just bought the peltier and its of 60 watt 12v 5a and its maximum capacity is of 90 watt power. I am using my Pc power supply which have ability to provide 12v and 15a maximum. I connect to that lead and check the current drawing using multimeter and my peltier only drawing 1.5amp at start and then keep decreasing until 1amp. Please help me that what is wrong with which thing ?
However peltier seems to be working because the colder side getting colder but not enaough because its only drawing 1 amp. However it have capacity to draw maximum 6amp.
To test it further, I connect it with my 12v 80ah battery and same result. Not sure why it is doing that.
For further investigation I connect two peltiers (Connecting red wire to red and black wire to wire) by connecting red wire to the postive terminal of the power supply and black to the negative and then I check the current draw and its drawing 3amp and then keep decreasing slowly slowly.
Not sure why this is happening, can anyone please tell me that what is wrong ?
