young how are you? Edgar here again greeting you
I hope everyone is well, in this video we are going to see a little bit we are going to talk about what are the power sources or the power sources
young how are you? Edgar here greeting you with another video with another class
Today we are going to see what the power source is, the first part since we are going to divide it in two so that it is not so boring
and so that we can understand little by little what we are seeing in our power source
our power source will serve us as a battery only that with a power source or a power supply we will be able to see the consumption
in amperage, we will be able to see in that area where the current consumption is shown we will be able to see that
and that way later when we get more experience we will be able to interpret them
so before buying a power source we need to know
we are doing this course for cell phones, for repair of cell phone plates
therefore we are going to need a source that gives us at least 5 volts, most sources deliver 30 volts but since 5 is enough
and we are going to need a source that gives us a minimum of 5 amps, 5 amps of current
so the sources are usually going to be 30 volts and 5 amperes of current
and something very important if you are going to buy a font for the first time make the expense and buy a font that is a minimum of 4 digits
that allows us to see even the smallest consumption and will serve us later
Another very important thing in mobiles is that we can unlock the function that is blocked when there is a short
that is sometimes very tedious because? because in cell phones we are working with a current of more or less 3 amps or 5 amps
so when there is a short we need to see even if it is about 3 seconds that consumption
so we can see if a component heats up or if we can see a component that is more current or that looks different
so we need a source, whether it does not block when there is a short or an over consumption or that we can remove that option
I do not have any brand that I tell you to buy this because it is better, the truth is that I started with a fairly cheap power source
still the one that I occupy in my workshop in the United States is quite economical
I think it cost me 3O dollars more or less there are sources of power up to 25 dollars plus clear shipping
but I don't have any brand that I can tell you buy this specifically because this is the best
like all things there will always be brands that are leaders or that are top of the line brands that are heavy right
So that you are paying a brand,
but you do not have to have a source of power to start so expensive, we will start with the most economical
I have a sunshine around here so I will try to get you an image to explain to you from other types of sources
when they don't have buttons like this to choose various options but only have 2 to flip
Before continuing with what is the source of power, let's understand a little theory
let's remember that what is entering our house is alternating voltage, that is entering our source of power
our power source will convert those 110 volts of alternating current, from alternating voltage that comes
it will convert and what we will have at the output will be a continuous voltage
so now we are going to move on to what is the power source and we are going to start to see a couple of parts
As I say this is a sunshine, I am not advertising this and it tells me that it is a power source of 30 volts and 5 amps
The question that many ask themselves is, Edgar, how often do I work, look
preferably we work with a current more or less than 4 amps, 5 amps, I sometimes use 5 amps
what you have to think about is the following
If I have, for example, a source that gives me a thousand amps, true, a thousand amps, which is a lot of current
and I turn on my phone and my phone only consumes 1.5, how much do you think it will consume
the 1000 or the 1.5? 1.5 then the phone will consume or the circuit will consume the current it needs
He will not grab more ok, so if I know that my battery works with more or less 3 amps then I put 1 more amp to have more or less a margin
in case there is any consumption I can see if it is hot etc, this is where an important part comes in because it is recommended not to have as much amperage
because if we have a short, let's remember that all the current that our source is giving us is going to catch and go for the short
Let's imagine that it is a short in a circuit and that makes us a hole between the plates so that's where the problem is
I personally work with a voltage of 4.1 or 4 volts and an amperage of 4 amps
I put 4 amps and 4 volts and with that I work
so when I have a short I start giving for example 2 amps, 2.5, 3, 4, 4.5 and up to 5
and if 5 does not heat anything there I already start with another diagnostic method
But understand this, if you have a source that can deliver 1000 amps, but your phone consumes only 2 amps
your phone will only consume 2 amps now the voltage is something else
but that is the difference, you can have your source to everything that gives
but always be careful that when there is a short, turn it off fairly quickly because all that current that you are delivering will go to the short
so that is the care that we must have, in this source we are going to have several parts
these are going to be the memories that means, the memories is that I can put for example a certain voltage a certain amperage and store it here
I can put another voltage and another amperage here to make my job easier
this works quite well when we are working enough numbers of phones because it makes our work much faster
the power button, if I turn on my source here, this source is telling me that I have 4.1volts right and I have 5.1 amps
right now this my source as in standby is not on we have this here which is lock and unlock which is that I can lock it
so that nobody is changing the sectors that nobody changes my values and in this case it can be blocked so that nobody touches it
in case they switch off here so that this does not change, look here I have this source in memory 1 I have 4.1 volts
In memory 2 I have 3 amps and in memory 3 I have 1 amp and in 4 I don't know how much I have 3.5 and 5 amps
so I have different variations
lock I already said what to do to lock and now we have OCP which is protection over current
this is what I was saying that we can deactivate it and activate it
because I take care of it here and when I have a short and it is activated, the source turns off
then i can disable it and leave it for at least 5 seconds so you can find the short
and this is OVP or over voltage protection
Now, we have the button of ohm off, Edgar, but this is not the button, what it does is release my source
So when I give it here, my source is already working
but if I have it here, the source is like in stanby
is waiting for me to give you here to send the output through its terminals
in the terminals we will have negative, positive and neutral
so we have these three terminals, so we usually connect the positive here and the negative here
This here will be to adjust, for example if I am here and I want to adjust in this case I want to put 1 volts here
then I turn off this that says voltage or current, and this starts to throb and with these buttons I can move myself to where I want to change
I can put this at 4.0 volts and I need nothing more than 1 amp
and I limit it to 1 amp
and that way I could already work, so let's agree that this enters what is alternating voltage that comes from there
enter this, this will convert and we have here this which is the user where we are going to be able to grab everything that is converting
and generate an output depending on our need, these are the parts of the power source
It is not a thing of the other world, I hope you have understood me, what a pity that I have no other source here different
but I will do my best to later make another video to see with those types of sources
so this is our source, we will see in the next lesson how it works, how to see those consumptions
and how to interpret them. for now we will leave it here, this class thank you very much always for everything
If you liked this class please share it, like it and leave me your comment
a hug to all and see you in the next video, bye
