使用场景 APPLICATIONS

1 Ideal for distributed power systems

2 Suitable for industrial automation equipment: Powering control circuits, sensors, actuators

3 Telecom and data center applications: Converting high-voltage DC bus to 28V for communication modules, server components

4 Industrial electronic systems: Used as a bus converter in equipment requiring stable, isolated DC power conversion from 200-400V to 28V

5 Applications needing compact, low-profile power modules with high reliability and built-in protections

注意事项 PRECAUTIONS

1 Mounting: Can be installed in any direction; when using multiple units side by side, leave sufficient space for ventilation to ensure aluminum base plate temperature stays within derating limits

2 PCB layout: Avoid placing DC input/output line patterns under the module (to reduce noise); design shield patterns on PCB connected to FG to minimize high-frequency radiation

3 Pin stress: Do not apply over 29.4N (3kgf) to input/output pins or over9.8N (1kgf) to signal pins; do not pull or bend pins with excessive force; use 3.5mm diameter mounting holes on PCB to reduce pin stress

4 Soldering: Follow recommended parameters—flow soldering at ≤260°C for ≤15s; input/output/RC1 pins with iron ≤450°C for ≤5s; signal pins ≤350°C for ≤3s (using ≤20W iron)

5 Cooling: Must use conduction cooling (transfer heat from aluminum base plate to attached heat sink); adhere to derating curves based on aluminum base plate temperature

6 Thermal management: Minimize temperature fluctuations if frequent power cycles occur to extend thermal fatigue life

7 Documentation: Read the official instruction manual and "Before using our product" guidelines before operation
