Circuit adjustable voltage regulator power supply with lM350 3A

Adjustable power supply (source) with integrated circuit lm350 high current

This regulated power supply uses the integrated circuit LM350K (metallic package TO-3) or Lm350T (TO-220) which allows to adjust the output voltage between 1.2 and 33V with currents of up to 3 Amperes.

An accessory that can facilitate your project is to use one of these modules of voltmeter and ammeter with display of led, available in electronics stores. If you have the patience you can even order from China for a price on account.
