WIRING A PWM (PULSE WIDTH MODULATOR) TO CONTROL HEAT

[@robertarmstrong5407]

I successfully built this from your video. Wow! Saved a ton of money on buying one and it was a lot of fun to build. I did add a lighted rocker power switch to the side. Thank you very much. Hope to see you back on KZbin again, if even only once in a while. Blessings to you and your family George.

[@LP23D6]

Thanks George for your teaching. I built a dial PWM by following your lead on a previous video. I found another use for it the other day on my crock pot. It really worked great. Much better than low, high and off. LOL

[@BarleyandHopsBrewing]

Excellent!

[@melmarshall8176]

Hello George. I hope you are looking after those ribs of yours. I live in the UK and just wanted to clarify our wiring to some of your folks. Most electronic device inputs will be marked with a “+” and “-” and perhaps an Earth. For us, if these are connected the wrong way round then there is a chance that the electronic device may be permanently damaged. Take care and keep up with your great work George. Best wishes from over the pond.

[@leperousbeing]

Truly a great series you're running here. Took me a lot of hours of head scratching and how the ****ing to figure out all you're laying out these past few videos. Wish you were doing this years ago when I was going through this same stuff and there was nobody breaking down and explaining this for our hobby. Well done!

[@BarleyandHopsBrewing]

Glad to help!

[@KYLE-jm6tr]

Thank you so much for taking the time to educate us on home distilling. I love your videos. Thank you for showing me the ropes. Look forward to a new video or a farewell sign off

[@coreyblackburn9289]

It's nice to see you rolling out new videos back to back!.

[@hines833]

I have bin looking at my pwm for a week now thanks I'll get it wired this week.

Commenting because I’m a big fan of your channel! Also, boosting the KZbin algorithm to promote your videos

[@joshuaclement8706]

I love seeing these simple power management projects

[@smartypants5036]

That's the cats whiskers all right. Puts the brewer in the drivers seat. Know your amps may be a Flossie but to know how hard you have the throttle down, priceless.

[@widgets76]

Much appreciated George! Have just had this exact model delivered this week so perfect timing!

[@BarleyandHopsBrewing]

Glad I could help!

[@Prem_hall_713]

I love to see passionate people still putting out incredible content! Great job sir

[@draw5233]

I just watchhed your vidieo. I built a pwm with a little twist I split the recieptical and added a second off & on switch to to control my water pump. I did not want to con trol the speed of the pump. I put a ball valve in to do that. Thank you very much for your insperation.

[@chrischris2886]

Thank you George. Any downside to the PWM with SCR vs. the Pot with SSR-40VA? Is one clearly better? Put off less heat? Any pros/cons to control heating elements and a pump motor?

[@nidaltouma]

Hi George, thank you for the educational video. May I ask a small question: I got a 10000W PWM, and I connected it to a boiler, with a digital volt-amp-meter on the output side to know the current and voltage going to the load. it worked but the meter got broken. could it be that some digital volt-amp meters cannot function with a quadrant wave ? I guess the PWM has a quadrant wave on the output, right ? I was sure of the connection of the meter because I tested it with another circuit and it worked fine... it is just the output of the PWM circuit that smoked it up. Thanks

[@robertserumgard2344]

I built one exactly like this at 240 volts in an old computer power supply case with a fan, I used an Iphone charger to power the fan, works perfectly. The fan runs a little slow at 5 volts but it is enough.

[@davidwalters9779]

How did you wire American 240 volts through this?

[@johnhendricks6398]

Good evening George. Outstanding videos. I am collecting the parts to build a 240 volt pwm controller to operate a 3500 watt element. 2 questions. 1. What gauge cables should I use, and 2. would the voltmeter/ammeter wire up the same way, just wit two hot wires on input instead of 1 hot and 1 neutral?

[@silly6004]

George, inside of the control box do you think a small fan such as a PC power supply fan would be necessary? If so how would you go abouts wiring it in within the system?

[@andydavis146]

Hey George nice video I made the 220 volt pid version for my 5500watt element can you make a video of how to wire 1 of these for 220 volts please?

[@robertschroeder1978]

Hi George, great video series. So looking forward to building my own project. I would very much like to include multiple digital temperature panels on the same box. Would be nice to see the changes of temperature on the still during the distillation phases. Great job and very grateful for the educational instruction.

[@BarleyandHopsBrewing]

Great suggestion!

[@charlesdean1542]

Much appreciate George

[@paultidwell8799]

16:32 still confused.. I know the light is wired to the female portion of the electrical outlet but what is the on off switch hooked up to??? what is the power source here??

[@antonioprado5257]

You have helped me so much to understand this hobby. I just wanted to know if you have had any problems with this new pulse modulator. I'm planning on building one, but was not sure if this modulator is better than the other model with this adjusting "turning" Nob. Please let me known thank you for all you have done for us.

[@justinsgarage1125]

Good evening George!

[@slelliott14]

It’s funny the seller says it won’t work with 120V. Guess you proved that wrong but unfortunately the digital is out of stock and says unknown on its return. I always wondered if they will work on 120v, now I know and will grab one asap

[@n8vmc469]

Perfect timing! Gonna need one of these!!!

[@justinsgarage1125]

While I would like to have the PID, this is much simpler and much cheaper 😅

[@justinsgarage1125]

@@robertt1782 that’s what I’m observing as I watch more videos. The do the same thing only different. PWM keeps it steady based on the dial(or digital “dial”) without the fluctuations. Again, much simpler and much cheaper lol. I’m trying to get into this while keeping the initial cost low and updating stuff as time goes by.

[@justinsgarage1125]

@@robertt1782 I’ve searched high and low for this PWM. I cannot get the 20A one with a fan. I can only find a 50a one with no fan. Will the 12v power supply and fan he used for the PID build cool this PWM sufficiently when it is mounted in such a way that it blows across the PWM?

[@justinsgarage1125]

@@robertt1782 and I just found another video. Now to figure out the difference between the SSR variable controller or the PWM controller. It looks like they do the same exact thing.

[@justinsgarage1125]

@@robertt1782 well I’m at a loss at the moment. Every sort of device is unavailable everywhere. I tried the SSR-40va...no heat sink or potentiometer come with the one I found. The PWM is out everywhere too. I think I may be able to piece it together.

[@danssv8]

Nice one mate

[@BarleyandHopsBrewing]

Thanks 👍

[@אהרןזיויקבאורהגנוז]

Thank you George . i use the PID controller and if i understand the PID will do the same but automatically , is that god to add as well ?

[@BarleyandHopsBrewing]

Correct

[@toddbishop9546]

Newbie at a cross road. Which one should I build for controlling my 10 gallon 4 bubble plate reflux still. Pid 240 volt 20amp controller for 3500 watt or a PWM? I figure they do the same thing. My concern is which one is better? Any help would be appreciated. Thanks Todd

[@gerhardnortje7336]

Hi sir iv got the exact motor speed controller you using there with the didigtal key pad,I'm trying to run a treadmill motor with it,I got it wired up with the bridge rectifier, now my problem is when I switch it on and press the arrow for starting it starts up at 30%thats way to fast and with another press of the button it climbs by 5%each time,I'm building a belt grinder,could a person wire in a actual manual pod? The 3 connector points of the pod and the 4 leads of the key pad throws me off a bit,the SCR,grnd,and 5v+ and zero,I don't know witch should go to the potentiometer,any help would be great

[@Zeus_Makes]

Hi, I love your videos. I'm trying to hook up a PID to 4 peltier modules with 4 fans. The issue is I'm trying to use the PID to heat and cool by reverseing the peltiers polarity. What kind of ssr setup do you think would work for that. Any advice is greatly appreciated thank you!

[@gbeaklrone6485]

Another Great video George. I built one of "your" PID controllers using the Inkbird but have not yet had the opportunity to use it. I am still piecing together my system. Which type of controller PID or PWM do you prefer? Happy Distilling!

[@bobtheelectrician6692]

PWM tend to be built down to a price. Skip the cheaper 4000W unit and go for 10K watts right away for the few dollars difference. Best to add a fuse in the supply circuit as well as a ground connection to the cage of the PWR. An indicated 50% power will not half the voltage/amperage... these things are not linear and often most sensitive between 40-50%. Much easier to control with the digital version rather than trying to turn a knob a few 100ths of a revolution. Once you have built and used one, you will wonder how you ever did without it.

[@schpoe123]

Can you add a plugin and switch for your water outlet being 240 volt?

[@angrypastabrewing]

Thanks for the tip, George. No pun intended.

[@paulhoffman4712]

G'day George whats the difference between a PWM and a variable controller. Not the technical difference but do they both control the same thing just using different method or does one control voltage and the other ampage?

[@thomascoker2399]

Goodmorning George, thank you for all that you do. I just got started about a month ago. I have been doing nothing but sugar washes so far. I am only yielding around 110 after all is said and done. We are running a 8 gallon pot still with a worm on top in a pot. No thumper. We use a 48 hour turbo yeast and have been doing 2 and a half pounds of sugar per gallon, and have been doing all the proper steps with temp and sanitization. Any tips to get the proof higher?

[@melmarshall8176]

Hello Thomas, I hope George doesn't mind me trying to answer your question. I've followed George for many years now so here are my thoughts. Fermentation not completed, or running the still to fast. If the fermentation of your sugar wash was not complete then you will end up with unfermented sugars giving you a lower ABV. What was your start and end gravity reading​? Running your still too fast. This will force more water vapour etc into your product, again lowering your ABV. The trick here is to be very patient, get the still upto a temperature where you get a very slow drip from the still and maintain that temperature for a couple of minutes. Increase the temperature really slowly now until you get four or five drips out of your still followed by a short spurt. All stills vary, I make batches of 28 litres of sugar wash and running my still in pot mode takes me around 10 to 12 hours to get 80abv 160 proof. I stop processing at 50abv 100 proof. I hope this helps. George may have more to say, but don't give up Thomas this is a fascinating hobby and George is amazing. Good Luck.

[@CapnBubbaa]

Can this work in a senario 240vac 30 amps, to 240v Recepticle, I assume the Neutral bypasses the Unit to the plug. If a tandem unit is used 240/120. If 1 240v is to used, and 2-120v plugs off each leg (it is a either or senario) will this still do its Job?

[@johnnytoy5487]

How do I get to the description of your PWM

[@chriserd2274]

So all the ones that I seeing or 220 volt does this work the same

[@WRDO]

Hello , "If the input is 240v-20amp and set the out put to 50% is the output will be 120v-40a or 120v-20a ?"

[@Muzz-rq9ps]

Hi George can you use a PID to heat your element,and also turn on your water pump at a set temperature? ie duel purpose

[@BarleyandHopsBrewing]

You could wire the pump into the alarm circuit and set it to turn on at a certain temp. Yes....

[@richardthompson14]

I love your videos but the SSR did not work at all. I tried several relays and the potentiometer that came with only changed the voltage 2 or 3 volts.

[@columbiabuzz]

Rather than calling it an "amperage transformer" call it a current transformer, which is what it is.

[@williamlietzke5358]

Good Morning George, A bit off topic but looking for advice on heating with the Pid on a copper still... is there a method for heating that should be followed ie temp increases?

[@agentjoshrtaylor]

What size wires are you using to connect these?

[@alphaomega9885]

12 it looks like for the bigger and I dont know what the smaller is but if you found out let me know.

[@RiggerBrew]

For higher AMP switching, without using a house light switch. Use these type of panel mount switches: ebrewsupply.com/collections/switches and use relays: ebrewsupply.com/collections/ssr-spdt-and-contactors

[@alphaomega9885]

Does anyone know what gauge the smaller wires are?

[@stuartpowell449]

I believe he's using 18 or 20 gage for the small wire.

[@coachetown]

I really cannot understand why anyone would give you a hard time about what you have provided here. I would really like to see this with 240 wiring but perhaps that is unnecessary. I am getting things together to do just that. Maybe I’ll post a video of it. Thanks so much

[@davidwalters9779]

Coach town did you ever do this?

[@44thala49]

I don’t see the advantage of this when a PID controller is about the same price and you can just give it a set point and let it do it’s thing.
