注意事项 PRECAUTIONS

1 Thermal management:Do not exceed operating temperature range (-40 to +105°C for TP1); follow output current derating curves based on ambient temperature and airflow to avoid over-temperature shutdown (triggers at115°C, auto-recovers when cooled by ≥10°C)

2 Electrical operation:

3 Avoid input voltage beyond60-160Vdc; transient voltage should not exceed200V for more than1s

4 Remote control (positive logic):Leave RC pin open to auto-start; connect to -In to turn off (auto-restart when disconnected)

5 Output adjustment:Use correct resistor values (per specs) for trim up (connect to +Sense) or down (connect to -Sense)

6 Remote sense:If unused, short +Sense to +Out and -Sense to -Out

7 Mechanical & soldering:

8 Soldering:Max temp is270°C for up to10s; use no-clean flux to prevent residue affecting isolation/reliability

9 Mounting:Ensure proper through-hole soldering; tighten heat sink screws to max torque of4.0kgf-cm (0.39N-m)

10 Safety:The product is a component; ensure the final device housing it complies with all applicable safety standards (e.g., IEC/EN/UL62368-1)
