greetings, before the box where the pic appears, there are some options for pic families, choose first there are all families and then below enter the pic you want to program gives you to connect and you must recognize the...

Greetings, if the source is linear, that is causally your problem that dissipates a lot of power internally and if it is short-circuited it is a disaster, they are small stoves. It will always heat up

The proposed power is a lot, but if it is for 12V, doing more than 1.5KW is an abuse the current to be handled is a lot. The most used integrated for that are the SG3524 and SG3526, look for...

Good . pc817 data is VF = 1.2Vdc IF = 5 mA, (you can use it up to 20mA) Then the calculation of the resistor is simple. R = (12V-1.2V) / 5mA = 2.16k, that may be the nearest commercial...

Regards . I suggest applying something like this: ; first define the pins that will be activated ; in each case let's say lamp1, lamp2, lamp3. ; using port b0, b1, b2. [b] lamp1 var portb.0 lamp2 var porb.1 lamp3...

greetings, you must divide the transformer VAs between 77v, to get the current, which will be the result of a full-wave rectifier with central tab,

Greetings to all. I want to make the query about the fact that this PC heats the processor a lot in a few minutes of turning on just presenting information from the bios since it does not have an operating...

good, check the status of the metro power if it is good, check if the triac is good.

good. in that circuit when the LDR has a very low value that is in the presence of a lot of light, it puts the base of the transistor to ground with very low resistance, so if the value of...

ummm, first the output voltage is very high, it should be between 110V to 120V being without load. 2- The charger stage may be incorrectly adjusted or the triacs defective and if so it will damage the batteries as well....

well in theory it should load completely under those parameters.

regards as seen it is 0.12 ohm, since the silver value runs two zeros so it has 12/100 = 0.12 ohm.

The circuit when energized has a small delay of about 0.5s to 0.6s, then generates a pulse that activates the relay and lasts...

good. as a contribution I can say that the pic as it is just a chip, requires more knowledge of analog and digital electronics, for the implementation of projects than the arduino, since the latter comes on a board already...

hola. esta pagina tiene circuitos modelos de disparo de triacs , puede usarlo e intentar que funcione con 12Vac , [url]https://markobonilla.wordpress.com/2014/11/07/practica-5-simulacion-de-metodos-de-disparo-de-triacs/[/url] creo que si lo poner a 12Vac y bajas los valores de los resistores podria andar ejemplo. el primero...

Buenas . los datos del pc817 son  VF=1.2Vdc IF=5 mA , ( puede usarlo de  hasta 20mA) luego el calculo del resistor es simple. R=(12V-1.2V)/5mA =2.16 k , eso puede ser 2.2k el valor comercial mas cercano. P= (12-1.2) x...

saludos. eso lo hace empleando un comparador , realice este le puede servir , nota la luz piloto debe ser de pequeño consumo menos de 1 Amp. [img]https://adjuntos.yoreparo.com/imagen_post/0004/73/465a950929fcd72d541757b1d6d5a1e338d0dc2a.png[/img]

saludos. para esas potencia le podrían servir estos . 1- [url]https://electronicabasica00.blogspot.com/2017/12/oscilsdora-para-inversor-dcac.html[/url] 2-[url]https://320volt.com/en/sg3524-dc-ac-inverter-projesi-250w-5000w/[/url]

saludos. un LM317T es un sencillo circuito que puede usar , en su hoja de datos esta el montaje , solo que para llegar a 15V con una fuente ATX , debera modificarla. este es otro proyecto interesante. http://www.esteca55.com.ar/proye-fuente-valdorre.html
