{601} Is It Safe To Connect Power Supplies in Series to Get More Voltage?

[@GannDolph]

Thanks for the follow up. This confirms what I meant by "the output circuitry probably already handles it". However, an extra diode does still offer extra critical protection against capacitor explosion in the case where the output diode fails. The failure would likely initially be a short, but the short could subsequently fail open due to current flow and then the capacitor(s) on that supply would surely explode! Love your channel - keep up the great work 👍🙏👍

[@HaseebElectronics]

special thanks for your feedback yes, diode can be added but it will create an extra passive load and will dissipate power. the capacitor will always have the -ve 0.4 volt in case of the power supply failure even if we use polarity protection diode, the lower side power supply will continue to feed to that failed power supply. so there will no benefit in both condition it is safe. if are using an extra diode or not

[@GannDolph]

@@HaseebElectronics I think there has been misunderstanding and I should have been more clear - my mistake! The diodes I have been suggesting are across the output of each power supply (reverse biased). They should not be conducting in normal operation. Definitely not series diodes (which wouldn't do anything except waste power, as you point out!) Thanks again sir!

[@HaseebElectronics]

Oh Yes. i got it you are right Best regards

[@3C371-v6r]

@@GannDolph well said my friend, in my experience with tinkering with psus, i have never seen a diode blow open circuit, but if that's the case, it could be potentially dangerous. Will be using diodes on the output of my series power supply now! Thanks for the advice!!

[@dantronics1682]

If its a properly designed psu the output cap are usually rated about twice the output voltage plus if the diode fails I dont think you will get a higher voltage

Good job done keep sharing

[@HaseebElectronics]

thanks a lot

[@rickybrenay6249]

Great video thank you. Only thing about connecting power supplies are making sure the series components are rated for the total voltage. Lets say you connect (4) 12v for 48V, make sure the components are rated for 48v and not 25v.

great sharing GOD bless you sir g

Many many thanks

[@diyaddictor]

Thank you for the video. When connecting to the power supply in series, one of them has to be insulated from the main ground wire, do you know why?

Hello sir I have a question I have installed led halo lit sign and connected with one 300 watt transformer and one RGB controller for some reason few letters are showing different color while changing the color with remote control and sometimes few letter won’t lit any suggestion will be appreciated these are large 24” high channel letters on outside

[@stanatkins09]

Hi I have a question How many amps would be for 2 x 12v 62a power supplies in series ? Would it be 24v 62a ?

[@HaseebElectronics]

If connected in series Voltage will be added 12+12= 24 volt If both power supplies have same current rating then 62 || 62 = 62 ampere 24 volt 62 Amp

[@ScrewBot]

Haseeb Sir can we connect 24v 10a smps in series with 12v 10a smps to get an output of 36v 10a? Please shed your view on this. Thank you in advance.

[@boydreamy1]

Asalam alakum. Haseeb sahib kase hi. Omeed karta ho ka kariyat se hongi. Haseeb sahib jis tara ap ni 2 supply's to series me kiya hai. Kya 12volt ka 2 battery chargers to ہم series me ہم laga sakti ha. Ager ap k پاس battery 24volt ki ho.

[@georgesdibeh7826]

Hello dear Can we use this connection to inject it into a hybrid solar inverter to test the pv input because mppt can range from 30 to 450 volts

[@HaseebElectronics]

yes dear it is usable.

[@georgesdibeh7826]

Thank you If you could do a test video Will be grateful I have a customer who has a 5.5 kw hybrid solar inverter And wants to turn it into an online ups Because they cost a lot So i was thinking is it possible to make a 5000 watt smps connection s/p And use it to power the inverter so that it always outputs 230 v 50hz

Salam M Haseed, i was wondering how many volts does the PSN #3 sees : 12v or 36v ? Thank you.

[@HaseebElectronics]

when 12v x 3 power supplies in series, it must be 36V

[@hichamtassi1753]

@@HaseebElectronics in that case should i change its o/p capacitors rated at 16v ? Thank you.

Thank you for your explanation. Very good indeed. How about adding power supplies in parallel? I've allways been worried about tiny differences in voltage. Thank you again for your videos.

[@HaseebElectronics]

thanks a lot for parallel connections. check videos number 597

[@homem.eletronico]

@@HaseebElectronics Thank you again.

[@dantronics1682]

doesnt the psu sense the output voltage? if it does then it should self adjust its output, but if you're that worried then just get a psu rated for the current output that you requires, do a search for solar panels connected in parallel

[@englishrupe01]

Really excellent information.....thank you. One thing does strike me, though, that maybe we should check that the main output to ground capacitor across (inside) each power supply is rated for the NEW higher voltage of the combined supplies, rather than their regular individual voltages...? Is this correct or not? Thank you, sir.

[@HaseebElectronics]

best regards and special thanks for your valuable comment each power supply's capacitor is responsible for its own supply's voltage. so combined voltage will not appear across any capacitor within a single power supply

I have 2 power supplies 12v 10amp i want to make it 24v to power my amflipier because i guess 12v is not enough it didn't sound good

[@revo2maxx]

So something I thought I would ask so I am clear on it. Isn't the case of your 3 power supply in your setup only able to supply the max Current of the lowest output power supply? So Because you used 2, 25amp power supply and then the 3rd is only 6amp isn't the max current at any Voltage now at the output only 6amp now?

[@HaseebElectronics]

Welcome dear yes, when we will connect 3 different power supplies in series, the voltage will add but total current will be limited at the lowest value of the power supply as i clearly explained in video number 598. i will suggest to check that video as well, please

[@revo2maxx]

@@HaseebElectronics Thanks for the Reply. Sorry I hadn't seen that video at this time and I just wanted to be sure if others that might have like me only seen this video know that in the case of your 3 supplies it is limited to the lowest current of the connected supplies. Now they know for more detail then can watch other Video for full Detail. Thank you. Great Videos. Wish you did Repair IP Camera videos as you do a great job of the videos I have seen of yours.

[@diyprojects5767]

Thank you sir, i have a question i have 2 power supplies with different output voltage and current, the first one is 24v 4amps and the other one is 12v 3amps. I connected them in series to achieve 32v 3 amps but when i connect the voltage drops to 8.8v. Does that mean the power supplies need to have same output voltage and amps rating?

[@HaseebElectronics]

there is something wrong in your connections if you connect properly +ve of first power supply to -ve of the second power supply take common output from fist power supply and +ve output from the second power supply's +ve terminal. then the voltage must add to each other and the total current will equal to the 3 ampere. because after 3 ampere the 12v power supply will shutdown

[@diyprojects5767]

Thank, will check out later

[@dantronics1682]

check the -ve to see if its tied to the chassic earth on each psu

हाँ वोल्टेज अंतर के कारण शॉर्ट सर्किट करंट होगा

[@cotto887]

the capacitors connected in series add the voltages

[@HaseebElectronics]

the capacitors are used to smoothen the output of the respective power supply. actually the giving an offset to the power supplies causes to add the voltage

[@cotto887]

adding the two diodes would drop some voltage

[@HaseebElectronics]

yes exactly it drops the voltage

[@wilsonjudy9515]

am pretty sure..... have added something to. my head

[@Globaltalentgt]

So many noise not stable voltage ⚡

[@HaseebElectronics]

no the voltage will stable, upto the maximum current (the maximum current having the 6 ampere in these 3 power supplies. otherwise the voltage are stable)
