Relays are fundamental, proven technologies to safely switch all kinds of loads. They do have their downsides, though, so if you need silent operation, precise timing, or the ability to operate orders of magnitude more times you might want to look at a triac instead. These solid state devices can switch AC loads unlike other transistor-based devices <a href="https://opensprinkler.com/using-triacs-to-switch-24-vac-sprinkler-solenoids/" target="_blank">and [Ray] at OpenSprinkler is here to give us an overview on how to use them</a>.</p>
<p>The key to switching an AC load is bi-directional conductivity. A normal transistor or diode can only conduct in one direction, so if you try to switch an AC load with one of these you’ll end up with what essentially amounts to a bad rectifier. Triacs do have a “gate” analogous to the base of a bipolar junction transistor, but the gate will trigger the triac when current flows in either direction as well. The amount of current needed to trigger the triac does depend on the state of the switched waveform, so it can be more complex](https://files.mastodon.social/cache/media_attachments/files/115/920/102/622/468/218/original/e6856b3e2fc3e33a.png)

Bin mir nicht so sicher, ob ich den Plan noch weiterverfolgen soll.
Wollte für eine Steuerung mit einem #Triac 2,5kw 230V schalten. Funktioniert zwar super, aber das Ding wird trotz Kühlkörper irre heiß...
Ich bräuchte quasi mehr Kühlleistung. Mit einem Triac ist das aber nicht so einfach, da die Kühlfläche auf dem Potential von L oder N ist. Dies ist eher suboptimal und geht dann quasi nur in einem Gehäuse...
Woran kann es eigentlich genau liegen das man sich ein Video auf invidio.us nicht ansehen kann sondern direkt auf YouTube gehen muss?
Das fiel mir gerade bei allen Songs von #Triac auf.

#Chiptune
Oh what a #chiptune night it was. Shout outs to #triac and #strobocop It was an honour to share a stage with you guys. In solidarity to our hosts at the JUZ in #Mannheim who are facing to lose the renting contract because of bullshit politicians.
Heute spielen #ToSeBit #strobocop #triac und #maevic im JUZ in Mannheim.Dem Laden den die CDU #bawü dicht machen will. 21 Uhr startet die erste Band. Kommt vorbei und lasst gemeinsam die #cduwegbassen #chiptune
