SUMMARY
The discussion centers on the safe use of Peltier elements powered by a 600W power supply unit (PSU) connected to a 230V outlet. The participants clarify that Peltier elements operate on DC current and cannot be plugged directly into an AC outlet. The maximum load of 15A at 230V translates to 3450W, allowing for multiple Peltier elements to be powered through a PSU, which converts voltage and manages current. It is established that the wall outlet does not perceive the load from the Peltier elements in the same way as it does for the PSU, thus ensuring safety when calculating power requirements.
PREREQUISITES
