How do I regulate an output of +12VDC from a +24VDC supply?
929646
Depending on the output current you desire and what current the +24 VDC can supply a simple 3-terminal regulator like a 7812 should do the trick. It should be able to handle the 24 V input. You may need to add a 0.01µF Cap from Ground to the +5 VDC output to dampen any oscillations. There are usually a number of cookbook circuits in the data books. \n\nGood Luck!

Bro, you may want to go big. Get a 650 watt power supply and you'll be set for a long time

You must understand power in = power out.\nSo the P(in) = 200A * 240V = 48000Watts \nTherefore, to obtain 400A out put you will sacrifice the voltage which will = 48000/400 = 120V\nYou need a heavy duty Transformer which will handle the 400A. The wiring size is 500MCM wire. Which is usually bus bar in a cabinet.\n\nTypically 240V 3phase line to line on a delta-wye Xfmr can provide 208V line-line provides 120V line-neutral. (208/sqrt3)\n \nUnless you have a Xfmr to convert, another way would be to use an active inverter, IGBT controlled.

go to radioshack.  they sell all kinds of converters etc.

Where are you going to plug in your DC heater?

Here are some sites that may help.  Both have circuit examples utilizing LVDT's.  Hope this helps.

I use a power inverter.

yeah you can use a switch (voltage switch) or if you can use binary logic, need to know how much voltage/current you are dealing with

What sort of prints? What sort of current do you want to source? How few milliviolts do you want?

I would probably use Light Emiting Diodes connected to a low voltage dc source using very small gauge twin-lead wire.

It depends on whether you simply want a boost in voltage value or a boost in signal power. In order to simply boost the voltage you need a transformer but if you want the signal the be boosted in power also you what you need is a simple amplifier circuit.Amplifier chips are available in IC patches

Try this web page:\n\nhttp://hyperphysics.phy-astr.gsu.edu/hbase/electronic/zenereg.html\n\nIt shows the basic circuit and has calculator to figure out component values.\n\nThere are much better solutions out there for a voltage regulators than zeners... such as the three terminal regulators like 78xx or LM317 types...

Your question is very vague.\n\nGive more description as what you want. or contacta  hardware engineer.

Since you have no contact info, I have no other choice...\n\nIn reference to http://answers.yahoo.com/question/index?qid=20061115060801AAEHWQA&r=w&pa=FZptHWf.BGRX3OFMhzdTUCYEW59bygAIQoCa4DY8zIlrypTkPQ--&paid=answered#NbUvWju8VzmdRHfXRHQU\n\nYou suggested to the asker to wire his sub to 1 ohm when it clearly states in his question "500 watts X 1 @ 4 ohms". You do realize you told him to blow his amp up by wiring it that way.

the input has to be the same unless you plan on plugging it into something other than a regular household outlet in the US.  the input is what it expects from the outlet you plug it into.\n  the output has to be 12V.  or else you might break your appliance.  the amps on the output can be greater than 600mA.  not less.  if your adapter is say 1000mA (1A) it has the capability of providing the 600mA your appliance needs, but if you have a 400mA adapter, it won't be enough.

Use the sine wave as 2.8 peak to peak volts to a bridge rectifier. No clamping is possible without dc power source and capacitance.

make sure you have them connect to 12 v, not 5 v, they should run at about 2500
