(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). 2 BUS CONVERTER EUS15-120 Model Mechanical Information Figure 1 Pin Assignment Table 4 Pin # Pin Name Function 1 Vi(+) Positive Input Voltage 2 En Input Enable / Disable 3 4 5 Vi(-) Vo(-) Vo(+) Negative Input Voltage Negative Output Voltage Positive Output Voltage Notes & Conditions Referenced to Vi(-).

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. Figure 12 Ordering Information
