使用场景 APPLICATIONS

1 Telecom systems: Suitable for -48V DC distribution networks (meets ETS300132-2 standards), powering base stations, routers, switches

2 Industrial automation: Control modules, sensors, actuators in harsh environments (wide temp range-40~+125°C)

3 Network infrastructure: Data centers, server power supplies, storage systems needing high efficiency and stable12V output

4 Embedded systems: Industrial PCs, IoT gateways, embedded controllers requiring isolated power conversion

5 Medical devices: Compliant with IEC/EN/UL62368-1 safety standards, suitable for non-life-support medical equipment

6 Railway&transportation: On-board or trackside devices needing high reliability (MTBF8.5Mh) and wide temp tolerance

7 IoT&smart devices: IoT gateways, edge computing devices requiring low power loss and efficient conversion

注意事项 PRECAUTIONS

1 Input voltage: Use within36-60Vdc (absolute max72Vdc; continuous over60V increases power loss, need temp≤+125°C)

2 Thermal management: Ensure TP1 (driver) and TP2 (PWB) temps≤+125°C; use airflow/heat sink (e.g.,¼" heat sink) as per derating curves

3 Remote control: Follow correct logic (positive/negative):

4 Negative logic: Open RC pin or >4V to turn off, <1V to turn on

5 Positive logic: Open RC pin to turn on, <1V to turn off

6 Provide min0.5mA sink current for RC pin

7 Capacitors: Use≥100µF external input capacitors; low temp (-40°C) needs larger capacitance; output capacitance100~10000µF with ESR>1mΩ

8 Installation: As component, ensure final product meets safety standards; maintain proper clearance between conductors

9 Soldering: Follow reflow profiles (SnPb: peak≤225°C; Pb-free: peak≤260°C); through-hole≤270°C for≤10s; use no-clean flux

10 Storage: Pb-free SMD products are MSL3, store in dry packs; bake if exposed to moisture

11 Parallel operation: Not allowed without external current sharing circuits

12 Guarantee: No implied warranty for merchantability/fitness for specific purposes (e.g., life-support systems)
