Sourcing out components for a PID build and have a few questions.
1) Can’t seem to get my head around solid state relays. Internet research suggests that a 40Amp is better than a 25 Amp relay although a 25 Amp will suffice for a 800Watt element drawing 6.7 Amps. Why would I consider a 40 Watt when 25 Amps is more than enough. House current is 15 Amps.
2) If I install a small fan is the enclosure do I still need a heat sink? I’m kind of thinking not but cooler electronics will last longer and perform better.
