I am making an indoor grow light using 10 watt LEDs. These LEDs use 110/120 VAC as an input (as they have their own, internal rectifiers and regulators). I envision using a Nano (old one) connected to a DS3231 to time the “on” and “off” times. Each LED uses about 10 watts apiece or just a bit under 0.1 amp AC, so I am looking for an appropriate AC relay (preferably Solid State) to use to turn the LEDs on and off, all at the same time.
At the moment I don’t know how many lights will be controlled by one relay, but that is no matter since I intend to get multiple relays to do all of the work.
Would anyone care to recommend a SS relay to do this job? And also if I have missed something, then please let me know of any impending explosions with the plan I have!
I thank you for your recommendations and constructive criticism!
You have a lot of options. This is a style I use, it works great with Arduinos and other electronic circuits. There is a small lets call it a quirk, because of how the internal circuit is designed for the triac it draws a small amount of current so with a few LEDs you can get a dim glow. Here is a circuit for a SS Relay: One way I use them is to place them in a metal box with a duplex outlet powered by a grounded 3 wire cable set. I run a 22AWG (convenient size for me) to the relay inputs. It works very well.
When I open it to edit the links are fine. If not open for edit nothing there just this funny square. Ihave never seen this befoe.
Thanks but I didn’t see any schematic but I really don’t need the triac control for the lights. These are bright, “grow” lights intended to provide indoor plants with light levels approaching the brightness of the sun. I suppose at some point it might prove useful to modulate the light output for some experimental reason, but for now I just want to turn them all on and all off.
Now that I think of it, the relay would also ideally be driven by a logic-level input, but I can add a driver stage if I needed to……
Not sure of what @gilshultz was showing as all the links are broken...
I use these for all kinds of ac switching application... What he stated may hold true for this, but I switched a 12A power supply on and off with one. There is also one in my laser that turns on the ventilation fan.
Seems to me it drew about 18mA from the 5V supply... They are pretty low cost...
Yes thank you. That is what I had envisioned for this but just wasn’t sure if they needed drivers, etc. With all of the lights on I’m pretty sure I can just use one relay.
