注意事项 PRECAUTIONS

1 Ensure proper grounding to meet safety requirements and minimize leakage current

2 Follow derating guidelines:Reduce load at high ambient temperatures (e.g., derate to90% rated current for output voltage <12V and -15~-30℃)

3 When using parallel modules for current sharing:Connect CS pins of all modules, ensure output voltage difference <0.2V, and do not exceed total output power (1200W)

4 For remote sense function:Use twisted-pair cables to reduce noise and ensure accurate voltage compensation

5 When using global ON/OFF control:Assemble the shorting connector (RC1 to GND-P) if no external control is applied

6 Allow sufficient airflow around the unit to prevent overheating and ensure overtemperature protection works effectively

7 Use manufacturer-approved accessories (shorting connectors, parallel cables) to maintain performance and safety

8 When programming output voltage/current (PV/PC):Adhere to specified voltage ranges and reference to correct GND pins

9 Avoid exposing the unit to moisture, dust, or corrosive environments to extend service life

10 Do not exceed the maximum current or power rating of individual modules or the total system
