使用场景 APPLICATIONS

1 Telecommunication infrastructure: Base stations, communication switches, and transmission equipment using 48V input power and requiring 28V output

2 Industrial automation: PLCs, DCS systems, servo drives, and sensors needing stable, efficient DC power conversion

3 Network equipment: Routers, switches, and data center devices with 48V power supplies

4 Test and measurement instruments: Precision tools that demand low-noise, reliable power

5 Transportation electronics: Railway signaling systems and vehicle-mounted devices (with proper conduction cooling)

6 Renewable energy systems: Solar inverters and energy storage units requiring DC-DC voltage adjustment

注意事项 PRECAUTIONS

1 Cooling requirement: Must use conduction cooling (e.g., attach a heat sink to the aluminum base plate). Operate within the derating curve based on base plate temperature (-40°C to +100°C) to avoid overheating

2 Mounting guidelines:

3 Do not route DC input/output patterns under the module to reduce noise; place patterns away from the module

4 Use copper patterns on the PCB as a shield (connected to CASE pin or mounting hole) to minimize high-frequency radiation noise

5 Leave sufficient space between multiple modules for ventilation; avoid overcrowding

6 Pin handling: Do not apply excessive force to input/output pins (follow stress limits). Fix the module with screws before soldering pins to prevent PCB damage

7 Soldering rules: Flow soldering at ≤260°C (≤15 seconds); soldering iron (26W) at ≤450°C (≤5 seconds)

8 Derating compliance: Avoid operating in hatched areas of derating curves to prevent excessive ripple/noise

9 Pre-use documentation: Read the official instruction manual and "Before using our product" guidelines (links provided in specs) for safe operation
