Cara Membuat Short Circuit Protection Power Supplay 1,25V-40V  Ide kreatif DIY


healthy greetings, youtube see you again with radal 05 this time I will practice how to make short circuit protection which is used for any voltage and current which certainly works the same way see, 1.3V output without load I tried short this is ground, this is positive i am short yes it’s off and the supply from the transformer is still on this is the indicator disconnected, input voltage to the regulator IC and display indicators and to revive I just press the switch yes … it’s on, it’s normal again ok … I try with a load 12V motorbike lights I close it first, so as not to glare my output voltage is 12V it’s 12V, I try it yes already alive and the current reads 0.65A ok .. I’m trying to short I connect to ground then I am short yes off and to light again press the switch on and back on, normal Remember that only the input voltage to the regulator is disconnected this supply indicator from the transformer and this is an output supply indicator how the series, before you you don’t forget to support my channel by subscribing if you want to subscribe for free click on the bell ok … I give this series a name protection current or short circuit I only use the relay, 12V what is important, the relay voltage must be under the voltage of the transformer we use because my transformer voltage is 40V so to make a 12V voltage relay I use zener, 2 pieces because I took the zener from the used charger if you use a 5V relay zener is only one piece and some resistors later at the end of the video, lots and sizes of resistors used. Because I also just made it because it’s 40V, I use R for 2K2 ohms maybe 3 or 4 pieces ok … so that I understand, I’m just drawing one by one 12V relay this is a safety diode you can use 1N4007, which is common then I put the zener in 2 pieces, so it was close to 12V because zener is on a charger, usually 5.1V this is ground ok I first removed the zener from a used charger This is zener, which I will release the other one, this a little different, no problem ok … I released the two then, my two zener series pay attention !!! this is a safety diode is mounted and note, the zener bracelet doesn’t turn upside down the direction is the same as the safety diode then I solder, on the relay then, the relay switch this is normally closed, normally open and I put the indicator ON and indicator of short circuit and this I give only a 2K ohm resistor because this is 40Vdc this Red indicator is short and normal led blue indicator I will give only 2K2, so that the led current is below 20mA then I solder, the blue led anode is normally open then the red led anode to normal close then the second led foot cathode I join and I give a 2K2 ohm resistor to ground like this then, normalize the oper I give a 2K2 ohm resistor to a combination of zener cathodes and safety diodes I minimize it, first the switch still relays you connect to rectifier output positive and this is ground This regulator is 40Vdc then I just put the switch on here resistor and switch to Vcc rectifier the name is … just switch on this value is 2K2 ohms I solder the cable to a positive rectifier then the cable for negative or ground then, I put the switch on one of my feet solder with R 2K2 ohm and one to Vcc finished the result is I glue it on the transformer only, so it can be easily seen before, you released the voltage that went into the regulator then I solder to ground and positive then the regulator input I connect to normal open finished we see the results don’t forget, you recheck again, before trying I input it to 220Vac yes already on pay attention !!! Rectifier indicator ON output indicator Off accidentally display it, I just made Off to make it more visible when off it looks clear ok … to turn it on switch ON … I press yes it’s ON and the display is ON I tried this regulator it doesn’t look clear, I was annoyed first yes it’s clear, you see the voltage is 1.33V no burden I tried short, right this is ground, this is positive i am short yes automatic display OFF and short indicator, ON and the supply indicator remains ON and to reignite you just press, switch ON I press yes it’s on, and normal again ok … I try with a load motorbike load only the negative this is negative and this is positive I close it first, so as not to glare I set the voltage at 12V ok … 12.1 Vdc I continued yes already alive the current is 0.65A then I will be short which cable !!! ?? the crocodile I connect to ground pay attention !!! I’ll be short yes … it’s automatically off to revive I press the switch on and display on again so I made, the supply to the rectifier is not off decided, supply to the regulator ok … I’m short again note the second indicator ok … I test the smallest voltage 1.33V I tried short yes … it’s OFF one more, resistor on the switch one more resistor on the switch I change because it uses a 2K2 ohm resistor the relay cannot be ON I replace it with 1K ohm it seems correct this is 40Vdc and this to the regulator input simple isn’t it !!! the series ok … hopefully you understand if you are still in doubt, you just comment, I will definitely reply thank you for visiting

  • Lhaaaa….video ini sudah diriku tunggu sejak 19 tahun yang lalu…😂😂😂

    Mbah guru, itu kan pakai relay 12 volt dan zener 12 volt juga, di shrt kan pada teg 1,3 volt dan di shortkan ladi teg 12 volt….
    Pertanya'annya mbah guru….., bagaimana kalau short pada teg di atas 12 volt, misal pada 19 atau 28 volt mbah guru…?, apakah masih aman ?🙏

  • Dua kali gagal om guru….
    Relay 12 v gagal
    Relay 5 volt juga gagal
    😭😭😭😭😭😭😭😭😭😭😭😭😭

    Boleh saya minta alamat email nya om guru…🙏🙏🙏🙏🙏🙏🙏

  • Pak saya masih bingung sendainya saya punya power suplay output dc 45volt dan saya pakai step down 3,8-40 trus berapa volt relay yg harus di pakai

  • Saya mohon maaf pada video gambarnya sedikit salah, yaitu resistor pembatas arus indikator bukannya terhubung dengan Vcc tapi dengan ground.

  • Pak radal mau tanya kenapa punyaku gagal ??padahal sudah ganti relay dioda ziner dan resistor awal saya coba relay 12 v ziner 12v resistor saklar 1 kilo resistor out yg ke dioda positif 2k2 input tegangan 40 tapi saya short relat tidak protek iktu kenapa???kunci keberhasilan itu terletak di mana pak

  • Pak saya pakai vcc 40v dc….saya udah ikuti skema tapi masih gagal untuk resistor yg ke led udah saya sambung ke grond tapi masih ngak bisa protek……kunci masalahnya kira kira di apanya yaa

  • Om guru aku dah coba dan berhasil,dengan mencopot zener 12v.tp kog aku pasang bayer bunyi terus y walaupun sudah NO .RESISTOR R4 sdh sesuai dg apa yg anda sarankan dividio yg satu.catu daya 30v.mohon solusinya

  • Gan cara pemasangan ke displai vol dan ampernya di mana? Atau lebih jelasnya tolong gambarkan urutan pemasangan mulai dr catu daya , shot protection , rangkain adjus/ lm dan disply nya?

  • Allora devo realizzare un circuito di protezione da 1,25v a 24v vorrei sapere i componenti da usare nel circuito, e il loro valore, che qualche passo nel video non lo capito bene

  • Untuk rangkaian yg ini bisa dijelasin dikit pake buzzernya. Soalnya kurang ngerti pemasangan seri ama led merah dan buzzer aktif itu yg kaya apa?

  • untuk tegangan rangkaian relayna ngambil dari mana om? misal sy buat power supply dari tegangan travo 12 volt dibuat variable 1-12volt ( pkai step dwon ) nah power buat relayna dari 12v sy sebelum kena step down atau teganyan output dari step down?
