power supply

hello everyones! i am a new visitor of ur community. my problem is
that i want to built my own regulated power supply for my experiments
of electronics.the power supply should be v&i regulated up to max 50v
dc and 10 amp regulated.i also want its display of v&i in digital
form. can any one help me about this regards

This is not going to be an inexpensive project, sir. We all would
like good electronics equipment, but are reluctant to pay the going
price.

Why don't you try a piece of used test equipment? It will surely be
cheaper than buying the components to make one yourself, and certainly
less than a new one.

You might want to look at the HP6274B, which will give you lab quality
constant voltage or constant current in the range of 0-60V and 0-15A.
Its only shortcoming for you is providing analog meters for voltage
and current rather than digital displays. You will probably spend at
least several hundred dollars for a working one, but it'll be a
bargain over trying to build something that big, especially for a
newbie.

Possibly, if you lower your sights on the current spec by an order of
magnitude or so, you might be able to build something yourself.

Good luck
Chris

The best advice I can suggest is enroll in local 'Hercules' club and in
about two years of intensive training you will be ready to tackle
physically this kind of monster.
The display is the easy part, I and V 'regulated' output is another
story altogether. Start with an appetiser of 25vX2A and then move on to
3/4 KW levels.
BTW you say electronics, those usually mean small amounts of power.

Good luck

Stanislaw.

hi,
frnd i don't know what is ur intention in making these large power
supply with huge current.In electronics we usually deals with currents
os the order micro amp. and a few volts and i think most of the
transistors and electronics devices now available are not cpable of
with standing ur requirements so that it is better to u to forget ur
project. GOOD LUCK IF U WANT CONTINUE WITH THIS ONE.

This would be a very expensive and a complex project. It would be a lot
cheaper for you to go out and buy a discent laboratory type bench supply
that would meet your needs. There are used ones around at a reasonable cost.

When building projects that work on the mains supply, there is a strong need
for the consideration for safety and to meet the proper standards.

There are plenty of applications of electronic circuits which involve
currents up to or even in excess of 100 amps. Motor drivers are a common
example. Look at the rcgroups.com forums dealing with electric model
aircraft; BLDC motors which take 30-80 amps are commonplace, and those
have to be driven by electronic driver circuits.

For a switched-mode power supply, 10 amps is trivial; the PSU in a PC
delivers more than that. SMPS which deliver hundreds of amps are common.

There are many companies which sell test equipment who can supply
you with exactly what you need for far less (in money and
aggravation) than it would take for you to build an equivalent power
supply.

As an aside, why do you find it necessary to flaunt the rules of
English when asking for help from an obviously English-speaking
community?

It's not like you don't know what it's about, it's more like you're
trying to change the culture.

Typical euro, yes?

Nah, just a googlie texter.

I didn't even know anybody still lived in Ur. ;-)

hi i start a project for a dual power supply unit
voltage and current regulation 3/5 or more if you want amp
and 0 to about 20 V output
overvoltage protection and short circuit protection
if you want to help me...
for the normal electronic's activity is optimal
