EN60950
Certified by TUV
Notes:
(1)
Vin = 48Vdc, Ta = 25 °C, Airflow = 200 LFM for all data unless otherwise noted.
(2)
Output ripple voltage and noise is specified when measured with no external capacitance.
(3)
Transient response is specified without a capacitor at the output of the converter.
(4)
Product operates with an external capacitance greater than specified. For higher values please contact a Celestica representative.
(5)
Thermal shutdown is monitored at the Thermal Measurement Location (TML). See ‘Mechanical Information’ on page 3 for TML location.
(6)
See ‘Safety Considerations’ shown on last page.
(7)
De-rating curves are conducted in a controlled environment. End application testing is required to ensure the Thermal Measurement Location
temperature is below the maximum specified.
(8)
Recommended airflow direction is from pin 1 to pin 3, or 3 to 1 (transverse airflow).
