Convert Atx Power Supply To Bench Power Supply


The two technologies are Bipolar Junction Transistors (BJTs) and Field Effect Transistors (FETs or MOSFETs), but for simple switching applications their difference isn't really that important. when I thought of this I was having a flashback to grade 7 electronics class lol where we used a similar method to connect led lights to a board as some Most LEDs only draw a max of a few dozen milliamps, so that might not be be enough current draw to keep the mystery "minimum load" circuits happy :-) Good luck!

I MRGGPRI Your "old" ps is likely seen its day and unable to produce current when loaded. . have a peek at this web-site

Is there a way to take a few of these power supplies and hook them together to run the amp? so i paid the 23 to get the damn premade board asap and I will have 2 chips once I etch the second version at home.

hi Matthew

currently my ATX power If you want to limit a specific binding post to only output a certain amount of current (1A, 2A, 5A, etc) then you need to use a fuse that will blow Valige oma keel.

Convert Atx Power Supply To Bench Power Supply

Presumably this is because it's easier and cheaper to include several smaller 12v regulators than to include one giant 12v regulator. It has a ground terminal for a wrist strap that ties to chassis, three voltage taps, and a switch to connect a DC barrel jack to one of three voltages. Since it's a 1997 factory stereo, I doubt the power is much higher than 20W per channel. You're probably better off looking on ebay for a cheap 14v power supply.

How do you determine which load resistor to use?

Once all the holes are drilled, insert the switch and the power terminals and fasten them in place. To test if your power supply has this requirement, press the power button and wait for a few minutes. When I turn on the power supply and connect it to the stereo, the power supply shuts off. Convert Computer Power Supply To Battery Charger If you will always have something connected to the supply when it is on, you may leave out the power resistor.

The traces and solder on the underside could still have high voltage on them if you didn't let the PSU sit long enough. Convert Atx Power Supply To Variable Benchtop Sajjad Haider Plz tell me how to make webaugur For our makerspace classroom I designed a laser cut case that slips over a standard ATX supply and hides all the wiring, Vaatamisjärjekord Queue __count__/__total__ Mis võivad olla põhjused?Sulge How to NOT convert ATX power supply to benchtop or lab power supply dansw0rkshop TelliTellitudLoobu tellimusest467467 Laadimine ... These lamps may be purchased at any automotive supply store and most Walmarts.

I consider working on that to i order to power the usb port.

My observations:

The PSU itself gives only 23V. Atx Bench Power Supply Load Resistor This would reduce the power burned as heat in the resistor down to 1.44 watts, so you could use a 5 watt power resistor instead of 10 watt.

Thanks alot, here's my You will also be receiving the weekly Make: Newsletter to keep you inspired with new projects and more product reviews. If you don't feel like soldering nine wires together to a binding post (as is the case with the ground wires) you can snip them at the PCB. 1-3 wires should

Chad Krause How many amps can you pull from the +12v rail? http://www.electronics-tutorials.ws/blog/convert-atx-psu-to-bench-supply.html If you turned on all the faucets and hoses and taps in your house, you might draw so much flow that you exceed the flow capacity of your water supply, and Convert Atx Power Supply To Bench Power Supply Cut a Slot in the Housing for the Female ATX Connector4. Using Computer Power Supply For Other Uses Here are a couple that you need to know about: Turning on the Power Supply It is designed to not turn on unless it is connected to a computer motherboard.

In the meantime, keep making stuff! Sometimes, if you're lucky, they have the wires labeled on the PBC of the supply.. BTW I designed a 3D printable custom enclosure for this project, here: http://www.thingiverse.com/thing:665797. http://nuvisiongraphx.com/power-supply/power-supply-from-hell-i-cannot-get-my-custom-built-pc-to-power-on-help.html Võite seda eelistust all muuta.

Just to exclude the resistor as a possible reason. Atx Bench Power Supply Kit Organize the wires with an electrical tape or zip-ties. 12 Check for loose connections by gently tugging on them. In most cases, a 10 watt 10 ohm resistor will work.

At first glance and because I do not have the components on hand to make it proper I thought a simple board with finishing nails through it on the one side

One other option we have is to use pin 8 - Grey (Pwr_Ok) as a visual indication that the PSU has started up correctly and is ready to operate. wtam69 22 193 kuvamist 9:56 Hacked ATX PC supply to Fully Regulated Lab Bench 5-16V 18A power supply !! - Kestus: 3:39.

Steps 1 Look online or at your local computer store for an ATX computer power supply, or dismantle an old computer and remove the power supply from the case. 2 Unplug But if you on the other hand read on the -12V, not the GND, then the maximum current is 1A. It should be 16 though if it was in any sort ATX computer in the last 10-15 years.
