In this episode of Lock your Hubs 4WDing, we delve into the intriguing realm of relays to explore the key distinctions between electromagnetic and solid state relays. If you've ever wondered which relay type is the right fit for your electronic projects, look no further! We conduct comprehensive speed tests to showcase the lightning-fast response of solid state relays compared to their electromagnetic counterparts, highlighting their efficiency and precision. Discover the factors that influence the reliability of both relay types, including failure rates and environmental resilience, empowering you to make informed decisions for your circuitry's long-term stability.
Furthermore, we unlock the potential of solid state relays with Pulse Width Modulation (PWM) applications, providing you with practical insights and techniques to fine-tune your control in various setups. Whether you're an electronics enthusiast, a hobbyist, or a professional, this video equips you with valuable tips and guidelines for choosing the most suitable relay type for your specific projects.

Great explanation as always, I like Solid state relays because they don't have contacts to burn out and become resistive, because the case is sealed, less prone to dust and moisture issues that cause that. Good quality SSRs are definitely worth the extra 👌
@LockyourHubs4WDing
@LockyourHubs4WDing 11 месяцев назад
I agree, under large loads, you might have to run a heat sink, but even then, I think it's worth it.

Brilliant video! Would have been good to see the mechanical relay attempt to dim the bulb using PWM. Would it flicker? Would it dim when the pulses are slow enough for the coil to de magnetise? Would the relay rattle itself to death?
@LockyourHubs4WDing
@LockyourHubs4WDing 4 месяца назад
Unless the cycle rate was very low, it wouldn't allow enough time for the magnetic field that activates the relay to collapse, so the relay would just stay on.

Awesome video mate i didn't know that these existed, Could you use a solid state relay to dim your 12v camp lights by adding a dim switch?
@LockyourHubs4WDing
@LockyourHubs4WDing 2 месяца назад
As long as the dimmer used PWM, it would work fine.

Some of your content would instantly go straight over my head (not this relay video) but the way you explain things makes me understand it instantly due to your explanations with diagrams. I didn’t even know there was solid state relays, haven’t really looked into anything solid state really so thank you. Also can you explain why they use the numbers they do on relays instead of say 1,2,3,4?
@LockyourHubs4WDing
@LockyourHubs4WDing 11 месяцев назад
That's a good question, I'm not sure why they use that particular numbering system on the conventional relays.

Thanks for another great video. Some of the solid state relays on the market appear to have inflated ratings and fail to switch the current specified. If you ever have the chance it would be good to see if that holds true in a practical application.

hi Sir, so could you use a higher current ssr to modify a dc welder for pwm i guess you would need a large heatsink attached to the relay for heat?
@LockyourHubs4WDing
@LockyourHubs4WDing 5 месяцев назад
I can't see why not, you would need a pwm spice where you can not only vary the frequency, but the duty cycle as well.

what you did not address is the efficiency of each of the two types of relays at various loads - the heat generated at various loads

Well explained as always. PWM - would this work on a water pump, allowing me to adjust the water flow? could then use a bigger pump and slow it down when needed....??
@LockyourHubs4WDing
@LockyourHubs4WDing 11 месяцев назад
Yes, you could definitely control the flow volume of a DC powered water pump with PWM.

OK so this all looks very technical but you have planted a seed of confusion in my non electronically trained brain. First: As I'm learning about relays I see all the other videos show primary power from the battery is in at pin 30 and out at 87 or 87a. The switch (on/off) goes through 85 and 86. You have those swapped around. Secondly on the solid state relay you have the power from the battery in on the terminal marked -4 then later you have power in at the 3+ terminal. Could you please clarify these points. Thanks
@LockyourHubs4WDing
@LockyourHubs4WDing 11 месяцев назад
30 is in and 87a is out NC, 87 is out NO. I might have messed up the diagram on the SSD, though the actual wiring is fine.

A solid state relay can work in a 12volt discharged battery?
@LockyourHubs4WDing
@LockyourHubs4WDing 8 месяцев назад
With the battery at a low state of charge?
@vicentecarrasco3653
@vicentecarrasco3653 8 месяцев назад
@@LockyourHubs4WDing yes,for example a 12volt discharged battery when is below 12volt.
@LockyourHubs4WDing
@LockyourHubs4WDing 8 месяцев назад
@@vicentecarrasco3653 the switched output doesn't really care what state of charge of the battery it's switching. The input switching voltage must be compliant with the specs of the particular SSR you're using. In this case it's 4-32v DC.
