使用场景 APPLICATIONS

1 Railway Applications: On-board train electronics (control systems, communication modules, lighting, passenger info displays) due to EN50155 compliance and wide temp range

2 Industrial Automation: Power for PLCs, sensors, motor drives, and industrial control equipment needing stable 15VDC from 48VDC input

3 Telecom & Networking: Telecom base stations, routers, switches converting 48VDC (common in telecom) to15VDC for internal components

4 Outdoor & Harsh Environments: Outdoor monitoring systems, weather stations, remote sensors operating in extreme temps (-40°C to +100°C)

5 General DC Conversion: Any system requiring efficient, isolated conversion from18-75VDC to regulated15VDC with high reliability

注意事项 PRECAUTIONS

1 Input Voltage: Keep within18-75VDC; do not exceed absolute max input of90VDC

2 Output Load: Do not exceed6.7A max current or100W max power; derate as per ambient temp (refer to derating curves)

3 Temperature Management: Use forced cooling or optional heatsink (-K) for high loads/temps to prevent overheating

4 Mounting: Follow mechanical dimensions; ensure sufficient airflow around the converter

5 Sense Function: Connect sense pins to load if using (short to output if not) to avoid voltage drop

6 Output Trimming: Use correct resistor values (trim down:-5% max, trim up:+10% max; input≥20VDC for max trim)

7 EMC Compliance: Adopt recommended EMC Circuit3 for48V models to meet EMI standards

8 Safety: Do not disassemble; avoid touching live pins; use10A slow-blow fuse and TVS diodes as per application circuit

9 Storage: Store in dry environment (-55°C to +125°C); avoid moisture/corrosive substances

10 Application Restriction: Not for critical life support, nuclear control, or hazardous environment systems (unless additional standards are met)
