Notes:
48Vdc, Airflow data unless otherwise noted. Output ripple voltage noise specified when measured with external capacitance. Transient response specified without capacitor output converter. Product operates with external capacitance greater than specified. higher values please contact Celestica representative. Thermal shutdown monitored Thermal Measurement Location (TML). `Mechanical Information' page location. `Safety Considerations' shown last page. De-rating curves conducted controlled environment. application testing required ensure Thermal Measurement Location temperature below maximum specified. Recommended airflow direction from (transverse airflow).

Safety Considerations
series converters certified standards listed `Standards Compliance' section table above. this product built into information technology equipment, installation must comply with above standard. external input fuse recommended), must used meet above requirements. output converter [Vo(+)/Vo(-)] considered remain within SELV limits when input converter meets SELV TNV-2 requirements. converters materials meet 94V-0 flammability ratings.
