0 30v variable power supply kit.

Because you can adjust an output voltage of 0v to 30v at 3a current and overload protection. I found that this cheap kit complete enables to build a very good quality laboratory power supply with features as it was advertised. 0 30v 3a linear power supply kit posted on january 21 2018 by mr. I decided to see what i will get and whether it will be good.

This is so the old circuit. It does not has a reference voltage for 723 and not fully overload protection. So it is small laboratory dc power supply in inexpensive cost. Also it is a high efficiency regulator using ic regulator ua723 and power transistor tip3055.

Please look at. Dc power supply variable switch cooden 0 30v 0 10a 4 digits display power supply adjustable regulated power supply digital with alligator leads cp3010s 4 0 out of 5 stars 7 76 99 76. Some time ago i have been ordered 0 30v 2ma 3a adjustable dc regulated power supply diy kit from china via ebay. 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.

This is a high quality power supply with a continuously variable stabilised output adjustable at any value between 0 and 30vdc. 99 5 coupon applied at checkout save 5 with coupon. 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. The power supply kit cost me just 5 29 so apart from the cpu cooler that i had.

This circuit is better than the above circuit. This is a 0 30v variable power supply circuit diagram. With a range of 0 30v and 0 3a it really satisfies all my hobbyist needs plus it was a very fun kit to build.
