Comment on Current Limiting Circuit by Tinggo

Mr.Hamuro & Mr.Markuson, do i have to calculate the power of Rb with this formula(example limited current Imax=2A)?
Pb = 2A x 2A x 15ohm
-or-
Pb = 66mA x 66mA x 15ohm

I’m a little confused because when Q2 on-off rapidly at short circuit load, the on state of Q2 will connecting Vs to Gnd via Rb.
Doesn’t it mean VRb=Vs?
Thanks before for Your further explaination.

thanks Mr. Hamuro for the design and Mr. AK Markuson for the additional explanations.
Just another question, if I’m going to add an LED as indicator of over current, where I am going to put it?

Oh wait, never mind, the plugin wasn’t working while previewing the page but it works on the published page. Sorry.

I just tried this plugin out. It creates a horizontal list of hyperlinked letters, numbers, and characters, but the links don’t bring up a list of tags. As I click on the links, the queries just get added to the end of the url like so: ?q=A?q=A?q=H?q=M. Maybe this is because I’m using the Simple Tags plugin as well; I don’t know. But your plugin doesn’t work for me.

Comment on 12V – 4A Power Supply by Technofreak

You can use the circuit in http://www.eleccircuit.com/12-volt-30-amp-by-7812/ . You’ll see 6 transistors for boosting the current, but for 8A, you can use just two sets of transistor-resistor. You have to provide very large heat sink since the transistor must dissipate 96Watt of power when a 12V drop voltage is developed across the transistor to supply 8A@12V.

I have a 24V 8A power supply. Using an LM7812, I want the output to 12V but retain the 8A from the supply, or atleast 4A. How can i achieve this?
Thanks.

Hello
I have a DC power supply with 4 fixed outs. 3.3vdc, 5.0vdc, 8.4vdc and 15vdc
How would I modify the Current Limiting Circuit to have a variable output from .5A to 3A for each output with an over current LED indicator for each output. I do understand that I would need four seperate circuits.
Thanks

Hi
Thank you very much
I used this current limiter circuit for a 4-20mA receiver.
