NUEVO PROBADOR de LEDS Seguro y Eficiente

Hi, I'm back with you in a previous video we saw how to make a universal LEDS tester with recovered pieces the link of that video I will leave it here on a card, for those who did not see it then we will also use the probes that we put inthat occasion, for better use that tester is very efficient and is designed for input voltage from 110 to 130 volts AC and many people asked me if they could use it with 220 input and you can make some changes but the correct thing is not to modify anything and use it through a 220 input transformer and 110 output for more security because with 220 is very dangerous and can receive very severe electric shocks thinking about that I bring you a testerof universal LEDs much safer with input of only 5 to 6 volts ofdirect current and you can use it with a mobile charger or may beportable with battery This circuit is very economical with few components and as always we will try to use recovered pieces to minimize the cost of this valuable tool is the equivalent to the Chinese LED tester that you find in the market with an approximate value of 600 pesos (30 dlls) and you can do it with less than 100 pesos between 4 and 5 dollars only If you want to know how to do it, watch the video we start Well this design is based on aN555 integrated circuit which is a precision timer and a MOSFET IRF840 Pay attention, I'll tell you one by one the rest of the components with the corresponding part number in the circuit and in the end I will provide them thediagram ah! If you have not subscribed to the SUBSCRIBE channel and activate the little bell so you can watch the next video that can also be usefulfor you we'll see the list of components, howwe mentioned earlier: an integrated circuit NE555 a base for that integrated circuit an 8-pin base an MOSFET IRF840 and we will now see the resistances in the diagram we will see how R1this resistance of 150 K the R2 will be a 330 K the R3 of 4.

7 R the R4 is 47 K and the R5 is 10 K let's now see the capacitors This is an electrolytic capacitor C1 marked in the diagram is 2.

2 uf to 400 volts the C2 is a capacitorof a 1 nano farad, with a commercial number 102 the C3 is a capacitor of10 nano farad, with commercial number 103 a diode, which is the only one in diagram 1N 4007 a coil with a ferrite core800 uH this coil getting a cardof a television the coil was obtained from a Main cardof a Chinese television and is also related to the voltage delivery of the LEDS 1 punched card I use a perforated card, youthey can use a breadboard or design the circuit to print it we will see the complements for a good finish 1 small plastic box 1 switch damper a fuse holder with a 500 mA fuse 2 jacks type "banana" or philips color black and red additionally it adapts a USB input I also got it from a cardTV and it's for 5 volt power We will perform the circuit test before placing it in its box here we put it with some alligators in the voltage output and this will be the 5 VDC power input from a cell phone charger And four batteries 1.

5 VDC each, which gives aApproximate 6 VDC let's see the output voltage of thecharger we have that they are 5.

12 VDC and we will also measure the batterieswe have 5.

82 VDC now we are going to proceed to connect the circuit and to do the tests with the LEDS we have the negative cable .

.

.

the positive and now the tips of the multimeterwe will place on the circuit voltage output this is the positive and this is the negative we must be careful in any way to NOT touch the tips let's raise the voltage of the multimeter to 600 volts and with the alligators we will proceed to make the tests there we will see the voltage output we connect to the socket, we have 285 VDC we proceed to test an individual LED You can try all kinds of LEDs fromindividual way too but it is preferable when they are individual, to test only with the necessary voltage and use the tester to test only the LED strips I have a strip of 12 volts let's try the blue line the red line and .

.

.

.

.

we see the green line let's also try a LED lamp We put the tips and we can also test partially but it does not arrive well, with the "alligators" so we'll test them last, with the probes we did in the last video These are four lines of LED strips and we put it in reverse, "they do not light let's put them in the correct polarity and we see that if he manages to turn on all theluminaires with a voltage consumption of 81 volts now we are going to proceed to the test with the batteries disconnect the mobile charger and connect the batteries we should not exceed 6 volts anymoreit will rise a lot of output voltage and could damage the capacitoror some component of the circuit or the LEDs that will be tested here we have the exit .

.

.

let's try again the individual LED, there they have it we tried the lamp the LED strip and we will also try all the LED strips, which equalsa lighting panel of a television we also trythe 12-volt strip as the last test and we are going to proceed here you see the blue, red and green we place the circuit at the entrance of5 VDC voltage through the fuse and damper and on the other side the exittowards the phillips jacks now let's cover and we will only proceed now to placethe screws Well the circuit is already in its box, we are going to do the final test this time we are going to use the probe that we elaborated in the last video It is much safer, being in: "ON" the voltage at the tips is activated, only press the switch switch that we have here at the tip and that will protect us more from somedischarge let's now connect the 5 VDC voltage already has its USB input to connect it let's put the switch in "ON" and we are going to do the tests withthe LEDs of the lamp that was left pending there we see, we cut the voltage right here for more protection and here we will see thatwe can partially test .

.

.

all the LEDs let's try the individual LED we have here, it's a colored LED There you see that it is lighting we are going to.

.

.

try the 12 volt LEDS The individual LED strip and we're also going to try .

.

.

make good contact there lights the entire LED strip good That's it in this video friendsI count on your support SUBSCRIBE, give "LIKE" and SHARE so we can continue with this project and keep uploading videos that can beof interest to you, see you soon.
