Today I was prototyping an upcoming hobby project of mine (wine fridge). I had the following components:
- 12V 3A PSU (2x) (link)
- 12V 6A Peltier module (link)
- Inkbird ITC-1000 Thermostat 220V (link)
I connected the 2 PSU's in parallel to obtain the 6A current, and connected common ground to negative of the Peltier module. Then I connected the common positive to entry 7 on the thermostat, and connected entry 8 on the thermostat to the positive of the Peltier module. I then connected by 220V AC to the power supply of the thermostat. For wiring from DC to the Peltier I have used jumper wires that I normally use for my Raspberry Pi.
I observed that everything was working fine, but that the positive wire connecting the thermostat to the Peltier became very hot! The plastic around the connectors began melting, so I turned off the power.
My guess is that the jumper wires are not able to withstand 6A current. Is this true? Which wires should I look for to support this setup?
