2 Output Ripple Voltage and noise is specified when measured with a 0uF tantalum and a µF ceramic capacitor at the output pins.
3 During output voltage rise time (5 mS Max.), output power shall be limited to 50% constant power.
Transient response is specified with a 960µF capacitor at the output of the converter.

SAFETY CONSIDERATIONS
This series of converters are certified to the standards and extent 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. Even though the product is safety certified to operate without an input
fuse, it is recommended that an input fuse of 2A (max.) is used.
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.
RoHS COMPLIANCE
The EUS34-096 converter is in compliance with the European Union Directive 2002/95/EC (RoHS) with respect to the
following substances: lead (Pb), cadmium (Cd), mercury (Hg), hexavalent chromium, polybrominated biphenyls (PBB) and
polybrominated diphenyl ethers (PBDE).

IN
= 48Vdc, Ta = 25ºC, Airflow = 200 LFM for all data unless otherwise noted.
Input transient: if input voltage increases by 5V in µs, output over-current shut-down shall not be triggered (tested with Max. load and Max. output capacitance).
Thermal shutdown is monitored at the Thermal Measurement Location (TML). See ‘Mechanical Information’ on page 3 for TML location.
See ‘Safety Considerations’ shown on page 4.
Derating curves are conducted in a controlled environment. End application testing is required to ensure the Thermal Measurement Location temperature is below the maximum specified.
Recommended airflow direction is from pin to pin 3, or 3 to (transversal to the unit).
