Reddit reviews GLE2016 Single Phase Solid State Relay DC-DC SSR-40DD 40A DC3-32V DC5-60V

I have build a C-Bot and am currently using a Fotek 40A SSR you can get off of amazon. This was the listing recommended by the creator of the C-bot in his rework design btw. I have it attached to the aluminum extrusions directly with some heatsink compound between them and it barely gets warm during operation.

You can hook it up as they recommend for the 24v configuration but that just provides the same amount of power at a different voltage so that doesn't help.


If you hook up 24v to the 12v terminals, you will quadruple the power and double the current.


Ohm's law, 12V=(1.2ohm)(10A) or 24v=(1.2ohm)(20A)


You would probably need a 600W 24v power supply and all of your wiring needs to be 10awg at least.


Hook it up like this diagram shows, except your bed power will connect to the 24v psu instead of the 12v.

Here's the relay used, be sure to heatsink it

This is the spare relay i have laying around. I believe it's DC to DC, right?

Awesome dude. I was in the same spot as you. Ended up using some of these, but I have an LED fixture, so it's not drawing as much power at T5s. It works really great with the pi, and now I don't have to fuck with having 3 or 4 timers, and can change or control it all from my phone or computer without the pain in the ass of stooping under the tank.
