Surface treatment: lead-free tin spray (HASL)

Base material: FR-4, blue solder mask

Assembly method: DIP plug-in + a small amount of SMT patch

I. Product features:

1. Power transformer and rectifier circuit:

The conspicuous toroidal inductor coil (transformer) and multiple rectifier bridge stacks and electrolytic capacitors on the board indicate that its main function is to convert the input alternating current (AC) into stable direct current (DC) for subsequent module power supply.

2. Multi-channel voltage output support:

The presence of multiple inductors, voltage regulator chips and diodes indicates that the board may support multiple output voltages, such as 5V/12V/24V, etc., to power different load devices.

3. EMI anti-interference design:

It uses red X capacitors, common-mode inductors and other devices, and has basic electromagnetic interference suppression capabilities, which is suitable for occasions with high requirements for electromagnetic interference.

4. High reliability component layout:

Use large-size electrolytic capacitors, high-voltage ceramic capacitors, thick film resistors and fuse structures to ensure reliability and safety under high-voltage input.

5. Modular panel design:

The entire PCB is a panel structure (4-in-1 arrangement), which is convenient for production and subsequent panel processing, and improves production efficiency.

II. Application scenarios:

LED driver power module

Power supply board inside power tools

Power supply module for industrial control equipment

Power supply board for small household appliances (such as air purifiers and water heaters)

Power supply unit for surveillance cameras

Auxiliary power supply system for medical instruments
