使用场景 APPLICATIONS

1 Railway Systems: Suitable for on-board communication, control, and monitoring equipment (EN50155 compliant)

2 Industrial Automation: Ideal for PLCs, sensor networks, and control systems requiring wide input voltage range

3 Telecom Equipment: Fits base stations and routers needing stable 48V from high input voltages

4 Renewable Energy: Can be used in solar/wind systems to convert high-voltage DC to 48V

5 Rugged Applications: Remote monitoring stations or field instruments (with robust protection functions)

注意事项 PRECAUTIONS

1 Remote Control: Standard negative logic—connect RC pin to -In for operation; disconnect to turn off. Positive logic (optional) starts auto when input is applied.

2 Thermal Management: Do not exceed 110°C at TP1. Auto-recovery after cooling >10°C.

3 Soldering: Pin temp ≤270°C for ≤10s; use no-clean flux to avoid residue.

4 Input Stability: Add 22µF capacitor if input source inductance >10µH.

5 Output Adjust: Connect resistor between Vadj and +Out (decrease) or -Out (increase); refer to manual for values.

6 Protection: OVP triggers at ~58V; OCP limits to ~1.05-1.25A; short-circuit current ~0.48A.

7 EMC: Use recommended external filter for EN55011 Class B compliance.

8 Installation: Ensure adequate heat dissipation; refer to derating curves for current under varying temp/airflow.
