❗Attention ❗ ----------------------------- please do not short the output + and - that can damage the transistor the current is limited by the input current
Add a fuse or current limiter before it. If you chose the latter option, you made an variable bench power supply that won't destroy itself or the stuff connected to it if it's set correctly..
can i use Reverse Polarity Protection Instead of using Short Circuit Protection ? i'm a bit confused of it because the voltage will be dropped, first i'm using LM7805 as the regulator with TIP3055 as the enhancement of current, and then when i use Short circuit protection in Simulation, the voltage is dropped, so what should i do ? thank you
@@Electronic_For_You okay, but I'm also making the 12 volt version with 10 amps, so can i combine Short Circuit Protection with Reverse Polarity Protection ?
greetings, they can be used to reduce the voltage of a 20v 2a drill battery to 12v at 1.5a. for another 12v drill. Wouldn't it overheat Much? I already tried the LM2596 dc-dc and the MP1584 and it doesn't work, it doesn't lift the drill very hardly, that's why I wrote to you while I'm still stuck in my project while I'm looking for other modules of these, if you know, let me know. Thank you, I appreciate it very much for here I saw a mofet I think it's a 5 amp round metal mofet.
Hello This is a linear regulator And not recommended for heavy load . I still recommend using buck converter its most efficient and do not heat ! And if you are talking about drill machine. I think no regular can stand the Inrush current of drill machine! You can power the drill from direct 12V .. Watch i have uploaded a video on computer Powersupply you can use that it can give 12V 20A
Excuse me, i want to ask again, so regarding to my regulator and Reverse Polarity Protection, which one is more make sense ? should i add the current with TIP3055 First and then the Output i add Reverse Polatiry Protection or Vice Versa ? thank you
Can i build mini variable power supply using two lm317, my power source is 24vdc 10A, first lm317 as voltage regulator 0-24v, and 2nd lm317 as current control 0-10A ?
Hello bro i am having a transformer and it will give me 18v dc and after rectification it gives me dc of 18v, with maximum of 3 amperes of current, now i want to connect 12v led'ss to it, but it is giving 18v so can i use this? Will it give me 12v with 3 amperes of current?
@@Electronic_For_You yes,I only change the resistance of 0.25 ohms, but I use two 0.5 ohms in parallel, because I can’t find 0.25 ohms, I think this should not affect
There is no short circuit protection on output. This why I used a 0.2 ohm resistor that will limit the current when shorted the output . and 1k is a load resistor if you don't put it there the voltage will not regulate correctly it will show 2v but when you load it will turn into 1v...!
@@Electronic_For_You do you know ic tc3582da? it is a charger ic with an indicator, can the ic be collaborated with tip3055 so that the current is bigger? if i can wait for the video
I need to increase Ampere from 1.5 to 3Amps max, in a 12v DC supply output. It's to power an amplifier module. What would be the easiest solution? Please help out.
@@Electronic_For_You I tried parallel 3055 X2 mounted on a 3X2 inch heatsink, connected 1K resistor on pin B, don't know if this is correct or not. and test loading at 4A for 10 seconds, causing moderate heat I don't understand how many Ampere can be loaded in 1 3055 datasheet.
2A for each TIP3055 ( short circuit current is 10A ) Not need to connect 1k to pin 2 connect all as shown in pic If your tip3055 is fake Then it will reach 100°c in just minute
@@Electronic_For_You I tried calculating the installation area of tip3055 and it takes up a lot of space if using up to 10 pieces. Can I use something instead of the 3055? Just 4-6 pieces. Maybe fit my box. Your clips and introductions gave me knowledge. Thank you very much for the advice
The last resistance, is protection for Power transistor . if the output is shorted the Transistor will not blow up your Face .... Only the resistance, get hot...!
Lm 317 linear voltage regulator is too stable, it doesn't work, it converts the drawn current into heat, it suffers power losses, I don't recommend it. Instead, lm2596 feedback, switched regulator with const. Modify Current Regulator. Available on my channel.
I mean when using do not Short circuit the output + and - that can damage the transistor because there are no current limit you can use it as voltage regulator....
Hi, I put together the circuit and it doesn't work for me, I use a 12v and 5amp notebook source. I put together the circuit and it doesn't work, could you upload the diagram or what am I doing wrong?
Incredibly, another misleading video. If you will to use the multimeter to measure amperage, please, show me which kind the load is (coil, resistance, etc.). but, in addition, if you give it a load without a heatsink, both, the regulator (LM317) and in the transistor, they would burn, and we have seen the smoke, product of the internal fusion of the semiconductors when exceeding the temperature vs load
@@Electronic_For_You Oh yes...!!! for no more than ....200ns...see the second page of datasheet of 2n3055....and you see....of course, if transistor has an internal fusion...the regulator go to see the LORD (GOD)
