VIN = 48VDC, TA@25˚ C, 300 LFM Airflow, VOUT = 52VDC, IOUT = Full load unless otherwise noted.
COUT = 180μF Al-Elec. Available output power depends on ambient temperature and good thermal
management. (See application graphs for limits.)

1. During short circuit, converter will shut down and attempt to restart once per second. The average current during this
condition will be very low and the device can be safely left in this condition continuously.
2. 50% load change only resulted in 1% output voltage step.
