(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 capac itance 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 cont rolled 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). BUS CONVERTER EUS15-120 Model

Ordering Information

The EUS series of converters are certified to the standards listed in the ‘Standards Compliance’ section in the table above. If this product is built into information technology equipment, the installation must comply with the above standard. An external input fuse (10 A recommended), must be used to meet the above requirements. The output of the converter [Vo(+)/Vo(-)] is considered to remain within SELV limits when the input to the converter meets SELV or TNV-2 requirements. The converters and materials meet UL 94V-0 flammability ratings. BUS CONVERTER EUS15-120 Model
