使用场景 APPLICATIONS

1 Railway on-board systems: Suitable for railway signaling equipment, communication modules, and control systems (complies with EN50155 railway standard)

2 Industrial automation: Ideal for DIN rail-mounted industrial control panels, PLCs, and sensor networks requiring wide input voltage range and isolated power

3 Telecom infrastructure: Applicable to telecom base stations and outdoor communication devices that need robust power conversion under varying input voltage conditions

4 Renewable energy systems: Can be used in solar or wind power systems where input voltage fluctuates widely (40~160Vdc)

5 Sensitive electronic devices: Provides stable, isolated power for precision instruments, medical equipment accessories (non-critical), and test and measurement tools

注意事项 PRECAUTIONS

1 Input voltage limitation: Ensure the input voltage remains within the40~160Vdc range; avoid overvoltage or undervoltage to prevent triggering protection mechanisms or damaging the converter

2 Output load management: Do not exceed the maximum output current of400mA (or6W output power) to maintain performance and safety

3 Temperature derating: When operating at temperatures above the recommended range (refer to derating curve), reduce the output load proportionally to avoid overheating

4 Mounting requirements: For DIN rail installation, follow the mechanical drawing specifications to ensure proper fit and heat dissipation; keep the heatsink unobstructed

5 EMC compliance: To meet EMC standards (EN55022 Class B), use the recommended EMC circuit with specified components (C0=100uF/200V, C1-C4=0.22uF/250V, L1=68uH, CY1-CY2=1nF/3kV)

6 Storage conditions: Store in a non-condensing environment with humidity between5% and95%, and temperature between-55°C and +125°C

7 Protection recovery: After overcurrent, overvoltage, or short circuit events, the converter will auto-recover once the fault condition is removed (except for persistent faults)

8 Wiring guidelines: Follow the PIN Out diagram for correct connections; ensure proper insulation between input and output lines to maintain isolation performance
