Tips

For redundant power configurations, use the current sharing function to parallel up to four units. Ensure adequate airflow in the rack—although the fan is temperature-controlled, proper ventilation extends component life. The auxiliary 5V output can power standby circuits or monitoring modules without an additional supply.
