Product Introduction

- Core Configuration:

3A Rectifier Bridge, supports AC and DC input

2*35V 220UF High - voltage - withstanding Capacitors, used for buffer filtering

High - quality Heat Sink, paired with heat dissipation fins to enhance heat dissipation

1.5A High - current Chip (Most similar products on the market use 1.2A or below, this one is better in quality)

Working Principle: Adopts full - wave bridge rectification, AC/DC can be input without distinguishing positive and negative poles; Uses 2 pieces of 35V 220UF large - capacity electrolytic capacitors for filtering to ensure stable and smooth output current; L7812 is equipped with heat dissipation fins and 3A rectifier bridge to meet the demand for continuous output of large current

Application Fields

Suitable for DIY power supplies, monitoring power supplies, experimental power supplies, camera power supplies, vehicle - mounted power supplies, power supply for communication equipment, etc.
