Power Supply Question/suggestions

For example:9VDC pedal that consumes 300mW (3/10 of a Watt). 300mW/9V = 33.33mA of current being drawn from the power supply.CALCULATING WHAT YOU NEED:Line 6 DL-4 which runs off 9V AC Its got a 9/12v AC output and you can use Y cables to get 18v.Personally, I'd look at some of the Cioks units. I only want to use op amps and passive components.

What's the exact english ... He was mentioning the danger of a particular light chain power supply because it was 'referenced to mains'. A load switch is nice, but not a deal-breaker.

The power switch must be a soft switch and something is broken (mosfet, I assume). As the output voltage sags, the pulse width will increase, and cause the final voltage to stabilize at either the peak value of the triangle wave (with little to no load), I'm a software developer trying out some electronics projects so this might be a stupid question but here it goes: Is it possible to put a coil around the mains wire Circuit Specialists CSI3005X5, 0-30V, 0-5A, $130.

having a large resistance).On my desk, for testing, I have an ATX powersupply that is "ON", but I have patched the fan to run off 5V instead of the normal 12V. Also, I beleive I need to drive the gate of the MOSFET with a pre-stage BJT, buy this does not help in my circuit simulator. The card I designed has room for power resistor loads, but in every case the output voltages were accurate and stable without any load. I would like to use only the 5V voltage of the Arduino.

  • Below are my goals on what to achieve.
  • at best, I figure it looks something like the image.
  • I do not have any oscilloscope or even a multimeter yet.
  • Where are you in the world, to advise further on scopes ? -max- (author)  steveastrouk3 years agoReplyThis was just the wiring for the green part.Only the triangle wave generator.

  • Thanks!
  • Voltage suppressors for the buck boost?
  • I would personally not hesitate to make a harness that connects to the GPIO pins, so that I can bypass USB cables to be sure that I don't run into bad

I plan to replace the pots in my supply with 10 turn at some point. –Connor Wolf Dec 23 '12 at 11:15 @FakeName Yah, I have several other supplies http://electronics.stackexchange.com/questions/276507/power-input-selector-and-regulator-design-improvement-suggestions Please turn JavaScript back on and reload this page.

The 1st one was that the face plate fell off and I had to use some double sided tape to stick it back on. this contact form I don't notice that, although you can certainly hear the relays changing taps, but the voltage seems fairly stable when it does so. –Garrett Fogerlie Dec 24 '12 at 16:16 So trying to sweep a range might not be a good idea, but for a variable steady supply it's great –Gustavo Litovsky Dec 23 '12 at 20:40 @gl3829 which Better to solder just a cable Enrico Like Show 0 Likes(0) Reply Actions Re: Power Supply Question Andy Clark (Workshopshed) Dec 23, 2016 9:55 AM (in response to balearicdynamics) The kit

I watched Dave's Review/FAIL video of it and then watched the follow up video and a follow up video by Charles Holtom from TrioSmartCal . I have looked far and wide, only to find a youtube video demonstrating a homemade scope. Uses up/down buttons for adjustment. have a peek here That gave me best results.steveastrouk steveastrouk3 years agoReply...and when you change the design frequency, you'll discover you need to change the op-amps to proper comparators. -max- (author)  steveastrouk3 years agoReplyWhat difference is

As long as you has clean power, you will not have added noise. Not really a problem if you can tolerate say +10%. I have since been using a old galvanometer and an led array or my tongue to measure voltage less than 5V.

Also, regulated power supplies CAN lose their regulation if you draw too much current.If your device only says the voltage in Volts and power in Watts, then you'll need to take

Yes, I made it! I've been planning on changing the pots too, it's just a bit hard to hit an exact voltage. Can be AC or DC input. Check This Out Aim for 40kHz +.

I'm guessing that this reduces the total allowed power output from the 500W it is rated at to below 100W or so, but it is currently powering two raspberry PIs and Otherwise it works nicely. Make sure its rated to handle it. I'd like to just have a single benchtop unit, if possible. –JYelton Dec 23 '12 at 9:39 @JYelton - If you stick a DM501 multimeter in the TM502/3, it

A few years ago, I grabbed an older powersupply from the pile of "old spare powersupplies" and it indeed behaved weird and required a load to be stable. Just being able to cope with 13.2V is much cheaper in the long run than adding a load resistor. No, just adding photos. Maybe diodes for each output?

Is it possible to write two separate Master's theses? The idea behind this PSU is to see if this idea will work or not.
