Key Features and Compliance
The converter is marked by its low profile at 0.28 inches, a light weight of 1 oz, compatibility with industry-standard footprints (1.45″ x 2.30″), and standard pinouts. The Q48T30018 is fully compliant with RoHS lead-free solder standards, meets Basic Insulation Requirements of EN60950, withstands input transients, and operates at a fixed frequency. It has an integrated LC input filter, offers remote output sensing, and has a voltage trim range of +10%/-20%.
Protection Features and Certifications
The converter ensures high reliability with an MTBF of 2.6 million hours and has comprehensive protection features like output over-voltage protection and over-temperature shutdown, among others. It is certified under UL 60950 in the U.S. & Canada, and DEMKO per IEC/EN 60950. Moreover, it meets FCC Class B and EN55022 Class B emissions requirements with an external filter.
Applications and Performance
This converter is ideally suited for telecommunications, data communications, wireless infrastructure, and server applications. It’s capable of operating effectively across various airflow rates, as indicated by Fig: 1 on the first page, which shows the available load current against ambient air temperature at different airflow rates.
Electrical Specifications
Electrical specifications dictate an input voltage operating range of 36-75 Vdc. Various thresholds such as input under-voltage lockout and input transient withstand are detailed, alongside output characteristics like current range and load capacitance. The converter also features isolation characteristics, including a 2000 Vdc isolation and details on switching frequency, remote sense compensation, and control features.
Additional Notes
Attention is drawn to the possible increase of the output voltage by up to 10% via the sense leads or trim function, with a caution that the total output voltage trim should not exceed 10% of the nominal value, ensuring the proper function of over-voltage protection.
Conclusion
Concluding from the given content of the first two pages of the datasheet, the Q48T30018 stands out as a high-performance, reliable DC-DC converter designed to meet the needs of power-intensive applications, while also adhering to rigorous safety and compliance standards.
