I do too! 10 years ago I used a PID temperature controller with relay output, and that thing did the job so well until recently (reptile heater, less than 1 amp load). Then I learned about SSRs and incorporated one of those, but I had to be concerned with SSR heating and such (even though at less than 1 amp the SSR hardly got warm it turns out...)

@6strings735

@@shantanuyadav6135 I assume the hoist is ON only at limited times, so probably yes. But 10A is too small. Use a 40A SSR and a heat sink. A 10A rating means 10A max, but if the relay is one of the inexpensive Chinese models, then it means 10A fries it. So always be safe and get an SSR rated for far more current than you will use. And remember that electric motors can have a high inrush current even if it is for a split second.

Not sure why they would say 40A unless it is a momentary peak, however, other than that there is not a lot that draws more than 15 amps for US homes as that is the circuit breaker rating for most plugs in American homes. My guess is that is the reason for 16A continuous load on these things, it gives them an amp to spare, tight but your breaker will pop before you overload this.

GreaScott! I am very happy to learn you torn apart that Fotek "Made in China" SSR. And I am happy you made this video about what you discovered. I had been planning to switch two electrical appliances with that SSR: a 1500W space heater (12.5A) and a 900W hotplate (7.5A), in order to power a smoker I built. However the total amperage is 20A. Therefore, I cannot power both devices off one SSR. I must either let the hotplate run continuously, and only modulate the space heater's power, or buy two SSR's, one for each device. By making this video, you proably saved me from burning up the "Made in China" SSR in my homebuilt smoker. Thank you! :)

0:42 Love your videos dude. ...but latching relays are thing. There are ones you pulse power once to turn on, and apply a reverse polarity pulse to turn off. There are also ones that have 2 coil terminals (4 pins on the coil [aka the switching signal side]). One coil is for latching on, the other is for latching off. IIRC Panasonic even makes a line that are "Small Signal" triggered with less than 15mA at 5 volts to power the coil. These should work with almost any MCU output. Digikey carries some of them I think.... anyways I was just looking into those a few days ago but still haven't found a small signal relay for 3 terminals and a double pole that will suit my project. -Jake

Hi, I work a lot with furnaces and have used these SSRs a lot.. Nice video and good breakdown. All good info.. Just to add, SSRs are usually optically isolated, ie an Led triggers switching. They come in both dc and ac activated(all it does is activate an LED which triggers ON/OFF), although the output is just a switch. I prefer AC control since wiring is easier. Also, as u said, these cannot be used for phase control (instead use an SCR or thyristor controller).. SCR can do variable voltage from 0_220v, whereas SSR can only do ON/OFF. SSR itself is silent, but most controllers used for such purposes still use mechanical electromagnetic relay and switching clicks can still be heard(not from SSR). SSR is cheaper in India (1$-2$) than raw material and ofcourse safety reasons u mentioned. Higher currents usually dont cost more and upto 100 Amps is 2$. Next project SCR??

SSR's tend to fail in the shorted position. This means that really bad things can happen when they fail. It would be nice to see a supervisory circuit that watches the input and output of an SSR which will trip a mechanical breaker if it doesn't work right. I was thinking about integrating it with a GFCI and deliberately shorting the GFCI hot wire to earth ground to trip it. A circuit like that would make a great video. I don't think you can buy them. I have looked.

I was thinking of making me a kind of soft start for a 2 kW motor (to be applied to the Parkside bench saw that will be on sale from next Thursday) and I had seen this SSR but apparently it does not matter to me zero crossing circuit. The greater problem is how to program an arduino for this (maybe an arduino nano is enough but i'm not sure) For sale I've seen soft start circuits with prices over 100 euros: too expensive! Regarding the danger of the DiY circuits, you must close it all in a plastic container and apply an insulation kit on the heatsink.

For safety, it is wise to use just 24V for experimenting (2:14), but you should further that safety concern by using an isolation transformer, and not an auto-transformer. The unintentional swapping of the brown (line) and blue (neutral) wire will present the mains voltage directly to the load, and that can be deadly.

They sell AC and DC coil versions but it seems their current ratings are unrealistically high. I used them with mains switching, to power water heaters [8-16A AC at 110-220V AC]. So far, the DC coil versions have been more reliable. I can power them with surplus laptop power supplies but this makes the job more ugly and more expensive! Danke schön!

They worked fine but if you a switching a highly inductive load you had to be careful to supply enough current to switch the triac or dual SCR on so current flowed both ways. You don't want to have it only conduct one way and deliver Dc to an AC device.

What would be good is to see how the 3 different speed buttons work and to add remote functionality. A micro controller might be the easiest way to handle the remove control, but it might be interesting to see if it an be achieved with standard components. Either way would make an interesting project. Thanks for today's video, another quality video.

Some triacs are isolated from the heatsink and hard setting thermal epoxy can also be used, giving greater isolation along with thermal silicone pads. The down side to triacs is they fail in the on position which is bad news when using heavy current. Heat dissipation can also be a big negative, especially in very hot conditions.

Zero crossing switch is actually a good thing for a relay. It reduces the electrical noise generated by the change of state. Phase control, on the other hand is more of a special case usage, and closer to the operation of a dimmer circuit. I could easily see the front end being driven by a mosfet, to allow very low level threshold voltage, or a OpAmp to have some hysteresis, which would be useful in temperature control.

Awsome. Is the dc output versions similar? But with mosfet?

You bought a counterfeit SSR. The FOTEK ones are one of the most counterfeit ones, and that's why it's has a 16A TRIAC instead of the advertised 40A.

As always, great information. I haven't read all the comments, but I am sure there are people telling you what you could do better. Or why aliens make everything you say null and void. But my suggestion is (I hope) less controversial. Suggestion: Buy a new yellow highlighter. That one is pretty much used up.

I have a small "riddle" connected with the subject. When apply DC 1st, then close the AC circuit manually (via switch), the uC that toggles the DC signal high gets reset. (It happens pretty much 90% of the time). It looks fine if AC line gets closed by the switch, then the DC starts to operate the relay... The relay was about $20 and actally looks quite solid. I wonder, what am I missing?

DIY or Buy: Amplifyer for stereospeakers. Maybe amps for like, 100W speakers, or for a entry point HI-FI system.

DIY or buy transformer. I know you don't like mains AC projects, but you could set something up using an H-Bridge so you have lower voltage. I also want to see the process of making a toroidal transformer. For an example, you could hook it up to an AC motor so people have a reasonable use case.

If you see constant running current through coil on relay as a problem, then pick a mechanical latching relay.. also there are 2 types of solid state relays.. the one you're using does in fact have a triact, but there is a fet version (for dc explicitly) available from china as well..

hi Scott, maybe it's in idea to try and create a noice canceling device for the next diy or buy episode! I'm loving your videos from Holland!

Hello GreatScott, i have some troubles with a TV power supply, when i opened it had a lot of capacitors blown up, i changed those but when i turn it on make a shock sound and still making a loop. What does that mean. You should make a video talking about the power supplies and few common problems that could has.

I purchased new switches made in the USA which I hope, after watching your video, will carry the amps stated on the hardware. Thanks

Since you were talking about TRIACS can you please make a video on how to control single phaze motor speed with triac? Thanks!
@paulbyerlee2529

I know this comment is old but if you are talking about a single phase induction motor then you are for the most part out of luck. Their speed is dependent on frequency. Triac only effect duty cycle (on vs off time) this will not effect the frequency or speed. A vfd however can change the frequency and speed for 3 phase motors from a single phase supply. For this buy is the best option.

Mr great Scott, at the end where you were able to power the bulb through the heatsink, you should know that there are special electrical isolating heatsink pads. Although you probably already know this but I said it just in case.

Yes, I am aware of that. I showed this example to demonstrate how dangerous a diy solid state relay can be if you don't know what you are doing. But thanks for the information anyway.

8:13 Why did you get 10mA for R1 calculation? Your MOC3020 uses according to datasheet 30mA for powering diode. 10mA is used for MOC3022.

I really love this series. As an electronic enthusiast by myself I ask myself frequently if I should buy simple stuff or diy it. Your videos are really a good at showing different aspects and really help me to make decisions. Thanks for that.

Can you explain another type of solid state relay made with 2 mosfets? The G3VM-601FR from OMRON is pretty intriging!
