The output is unregulated and the 5:1 fixed ratio is maintained between the input and output voltages. It features input voltage range of 38V to 55V, and provides up to 300W @ 48Vin of power. Typical efficiency of 9.6V module is 96%. It can be parallel for more power.

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 12A (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). For further information, please visit www.cd4power.com/rohs 1 2 3 4 VIN = 48Vdc, Ta = 25ºC, Airflow = 200 LFM for all data unless otherwise noted. Input transient: if input voltage increases by 5V in 1μs, 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 1 to pin 3, or 3 to 1 (transversal to the unit). www.murata-ps.com Technical enquiries email: [email protected], tel: +1 508 339 3000 EUS35-96.B01 Page 2 of 3 EUS34-096 Isolated Bus Converter PACKAGE SPECIFICATIONS MECHANICAL DIMENSIONS 0.480 (12.19) Max.
