For all electronic user. You can Current control by VR 5K, LED5 For display OVERLOAD.
To use transformer 3A, Transistor to Hold Heatsink. To adjust the output voltage< VR1 - 5K (VOLT CONTROL)
OUTPUT : 0V to 50V , 2A
Today I would like to introduce you to DC Voltage adjustable regulator voltage between 0V to 50V and current up to 2A. Which are suitable for various electronic circuit, when viewing circuits in the figure, many people will think that, in this circuits outdated, but I think, it is also highly effective are.
The VR2-5K be adjusted voltage output between 0 to 50Volt.
-The VR1- 5K be fined current output load 0 to 2 Amp.
- When the short-circuit current limit or severe, it is a good system.
- Low noise, due to the use IC uA723 dc voltage regulator IC which is high quality, widely used for many years.
