Feature: 1. 3A RECTIFIER BRIDGE: LM7812 is equipped with a 3A rectifier bridge, both AC and DC can be input. Supporting heat sink to enhance heat dissipation 2. 1.5A HIGH CURRENT CHIP: Using 1.5A high current chip, which can meet the continuous output of high current. The same network products generally use 1.2A and below 3. SUPPORT AC AND DC: This board use full wave bridge rectification, support AC and DC, and the input is independent of positive and negative poles 4. STABLE AND SMOOTH OUTPUT CURRENT: Filtering uses two 35V220UF large capacity electrolytic capacitors as buffer filtering, which can make the output current stable and smooth 5. VARIOUS POWER SUPPLY: Can be used for DIY power supply, monitoring power supply, experimental power supply, camera power supply, vehicle power supply, communication equipment power supply Specification: Item Type: Regulator Module Input Voltage (withstand voltage): DC: 15~24V AC: 12~18V Output Characteristics: Load Regulation Rate: 100MV Quiescent Current: 8MA Output Noise Voltage: 42UV Input and Output Pressure Difference: 2V Output Impedance: 15MΩ Peak Current: 1.5A Maximum Load: 10A/250VAC, 10A/125VAC, 10A/30VDC, 10A/28VDC, 10A/12VDC Module Size: Approx. 43 x 20mm / 1.69 x 0.79in.
