I'm building a magnetic stirrer. I wanted to add a heated bed and I've been looking at peltiers as a heat source. To control the temperature I've identified the "WH7016K", a Chinese-made temperature control system designed specifically for direct peltier control and it's only about 20 bucks.
However, the data sheet for the device says the max load of the relay is 8A/30VDC or 2A/220VAC. If I'm using a 12VDC peltier is it safe to use one that draws 5A? Am I correct in assuming that the relay has a max load of 240 watts and the 60W load of a 12V/5A peltier should be fine?
Manual for the device is available here, but it is fairly sparse. It's also a word document so heads up if that rubs you the wrong way.
