Phase Three Phase
is_customized No
product number LB1757
Size 43mm*20mm

Product Description

1) 3A rectifier bridge (AC and DC can be input)
2) 2*35V 220UF high withstand voltage capacitor (for buffer filtering)
3) High-quality heat sink (with heat sink to enhance heat dissipation)
4) 1.5A high current chip (the same network products generally use 1.2A and below, cut corners)

*This board adopts full-wave bridge rectification, AC and DC can be input, and the input does not distinguish between positive and negative.The filter uses two 35V 220UF large-capacity electrolytic capacitors for buffer filtering, which makes the output current stable and smooth.The L7812 is equipped with a heat sink and a 3A rectifier bridge for high current continuous output.
Application areas: DIY power supply, monitoring power supply, experimental power supply, camera power supply, vehicle power supply, communication equipment power supply.
