Knowing just about enough about electricity to be dangerous, I would like to ask if anyone has tried powering thier pelts using this configuration. I would like to run 3 80 watt pelts in series using the positive 12 volt and negitive 12 volt line on my psu. The power supply is good for 20 amps on the + 12 volt line and 5 amps on the - 12 volt line.
So what would the current total be? 25 a or 20 a or 5 a. I figure that it will be at least 20 amps. Then I'm also wondering what the voltage drop will be across the three pelts.
So let me try some math here... If you take three 80 watt pelts in series you have a total wattage of 240 watts. If you take that total wattage and divide by the volts you would have a current of around 10 amps. Knowing total amperage and total power I figure each pelt will drop about 8 volts. Now because they are in series my psu will only need to put out 10 amps and 24 volts.
If anyone has tried this please let me know. If anyone dissagrees with my thinking, I look forward to hearing from you.
