Q48T15050 DC-DC Converter Key Features and Specifications

The Q48T15050 DC-DC Converter by Power-One stands out for its compact, high-efficiency design suitable for a range of power applications, in particular telecommunications and data communications systems. This converter is engineered to deliver ultimate performance with a very low body profile, which is especially beneficial in dense power-conversion environments.

This DC-DC converter is characterized by a wide input voltage range of 36 to 75 VDC, and it provides a stable output of 5 VDC at 15 A. With its industry-standard quarter-brick format, the converter boasts remarkable features including:

RoHS Compliance: Adhering to RoHS environmental standards, with both lead-free solder and lead-solder-exempted products available.
High Efficiency: Up to 88% efficiency at full 15 A load, and 87.5% at half load.
No Minimum Load: Reliable operation without a minimum load requirement.
High Reliability: With a mean time between failures (MTBF) of 2.6 million hours based on Telcordia TR-332.
Thermal and Mechanical Advantage: Low profile (0.28in / 7.2mm) and light weight (1oz / 28g typical), reducing airflow shadowing which helps in better cooling for downstream devices.
Comprehensive Protection Features: Including remote output sense, over-voltage protection, over-temperature shutdown, and auto-restart post-failure.
Flexible Control Options: Indeed, with positive or negative logic ON/OFF options and an output voltage trim range of +10/-20%.

Electrically, it supports an external load capacitance across a broad range with features like non-latching current limit inception and both RMS and peak short circuit currents accounted for. These capabilities are complemented by electrical isolation specifications ensuring safe operation.

The converter is designed to withstand input transients of up to 100 V for 100ms, and its operational and storage temperatures range from -40°C to +85°C and -55°C to +125°C, respectively. Moreover, the device meets the Basic Insulation Requirements of EN60950 and it is certified to UL 60950 standards in the U.S. and Canada, as well as DEMKO certification per IECIEN 60950. It also complies with FCC and EN55022 Class B emissions with an external filter.

The converter’s output features and utilities are further detailed in its electrical specifications, highlighting the ease with which it can be integrated into a variety of applications. This includes telecom infrastructure, data communication systems, wireless networks, and server power solutions, pointing to its versatile application range.
