0 30v 3a linear power supply kit posted on january 21 2018 by mr.
0 30v variable power supply kit.
This is a high quality power supply with a continuously variable stabilised output adjustable at any value between 0 and 30vdc.
It does not has a reference voltage for 723 and not fully overload protection.
The circuit also incorporates an electronic output current limiter that effectively controls the output current from a few milliamperes 2 ma to the maximum output of three amperes that the circuit can deliver.
Please look at.

So it is small laboratory dc power supply in inexpensive cost.
E it has become pretty common for me to have one or two unfinished projects on my bench or the shelf because i just can t find the time to complete them or because i m waiting for something the project needs.
The power supply kit cost me just 5 29 so apart from the cpu cooler that i had.
Also it is a high efficiency regulator using ic regulator ua723 and power transistor tip3055.
This circuit is better than the above circuit.

I found that this cheap kit complete enables to build a very good quality laboratory power supply with features as it was advertised.
Some time ago i have been ordered 0 30v 2ma 3a adjustable dc regulated power supply diy kit from china via ebay.
0 50v 3a variable power supply 0 30v 0 5a variable supply with current adjustable.
I decided to see what i will get and whether it will be good.
This is so the old circuit.
