L7812 LM7812 Three-terminal voltage regulator 12V voltage regulator module 12V voltage regulator power module

1) 3A rectifier bridge (AC, DC can be input)

2) 2*35V 220UF high voltage capacitor (do buffer filtering)

3) High quality radiator (equipped with heat sink to enhance heat dissipation)

4) 1.5A high current chip (network products generally use 1.2A and below, cutting corners)

The board adopts full wave bridge rectifier, both AC and DC can be input, and the input is not positive or negative. Filter using two 35V 220UF large-capacity electrolytic capacitors as buffer filter, the output current can be stable and smooth. The L7812 is equipped with heat sink and 3A rectifier bridge for continuous output of high current.
