Tips

For optimal performance, ensure adequate ventilation around the unit and avoid covering it during operation. When integrating into a medical device, verify that the total system leakage current remains within the limits of your application. The output cable length and connector polarity are fixed; if a different plug is needed, use a suitable adapter that maintains the required isolation and current rating.
