DC Curent and Voltage regulation.

[Mark Van Skiver]

Can build variable power supply relatively easy for low voltage & current. Check radios shack projects for more details.

Please don't use this as a power supply... it looks like it's simply a beefier version of a light dimmer... which means it operates on a sort of 'PWM'.
It chops up the AC waveform as it goes out... the more that is chopped off, the dimmer/slower the light/motor goes. It does not actually regulate voltage in any way.

Thanks didn't know that

I will thanks

Ok i won't use it as a power supply.
Is this a good Multimeter for the buck or do you recomend something diferent?

I like how it 'looks' and I like the functions, but I am always weary when the price seems to good.
I don't have experience with that name-brand.

Ok and what kind of a multimeter do you have if you owe one?

I've got a basic little Fluke meter. (Can't remember the model)
It does not have the extra functions. I can do Resistance, Voltage, and Current.

So its orobably similar to my brothers/mine UNI-T ut33d

Years ago, I saw a "Power Pump" in a CB magazine and the plans to make one. It was a 'plug-in' that converted 110 VAC to 12-13 VDC with a rock solid output. There was an option to see just how many amps was being used when the CB was being used. The specific voltage could be controlled by a specific resistor. The whole thing fit inside a 3" x 3" x 4" box. I built one and used a mobile CB, in the house as my base station. It could also have been used as a 12V battery charger. Slight research, may find the answer to your project.

looks respectable, for $30 if you get several years out of it ( you may get much longer) before you have to replace it ... it's a great deal, has a good range of test modes

So its orobably similar to my brothers/mine UNI-T ut33d

those things are shocking compared to FLUKE which are the industry standard. My FLUKE is over 30 yrs old and still chugging along

Thanks for the opinion apriciate it.

Thanks for the opinion apriciate it.

I only made the UNI-T comments out of personal experience
the previous company I worked for the boss bought 5 of them one for each of the workshop and on-road techs
none of them lasted more than 2 years, 2 of them died within 6 months !!

one would hope their quality has improved over the last few years ... but regardless, I wont touch that brand again
