WebAug 12, 2024 · The reflow process starts when we press the start button. Here you can see the graph based on the reflow profile that we have set in the code. Then the heater starts and the PID algorithm starts controlling the temperature. The while line represents the current temperature and as you can see it pretty much follows the defined graph. WebThe Reflowduino Pro's opto-isolated solid-state relay has a control voltage of 3-15VDC and can handle up to 25A/240VAC with proper convection cooling. Under normal circumstances it can handle 10A/240VAC, or 20A/120VAC which will be good enough for all US appliances and should be adequate for most 240VAC appliances. Resources:
