TA=25°C, airflow rate=300 LFM, Vin=48Vdc unless otherwise noted; full operating temperature range is -40°C to +100°C ambient tem-
perature with appropriate power derating. Specifications subject to change without notice.
Note 1: For applications requiring reduced output voltage ripple and noise, consult SynQor applications support (e-mail:
support@synqor.com)Note 2: Higher values of isolation capacitance can be added external to the module.
