Power-One Intros Hi-Perf DC-DC Converter
Hi-performance DC-DC converter.
Camarillo, CA — Power-One, Inc. is introducing a new eighth-brick DC-DC converter that provides 12VDC at 10A, the SQE48T10120. High efficiency of 93 percent at 120W, and excellent elevated ambient-temperature performance are achieved through the use of advanced circuits, packaging, and processing techniques. A low body profile, and the preclusion of heat sinks, minimizes cooling airflow impedance.

Designed to be used in communications systems and data servers, the new converter reportedly offers applications flexibility and has a user-adjustable output that can be trimmed from -20 percent to +10 percent using industry-standard equations. Tight output regulation, ±2 percent, provides the versatility to power input-voltage-sensitive applications, as well as providing IBA bus-converter power.

Other features include: low-profile height of 0.374-in. (9.5mm), wide-input-range operation of 36 to 75VDC, an on-board input differential LC filter, remote sense, and start-up into pre-biased loads. The SQE48T10120 is protected against input undervoltage, overtemperature, output overcurrent, and output overvoltage. Regulatory agency approvals include UL60950, including basic insulation requirements. This product is designed to meet Class B conducted emissions, per FCC and EN55022, when used with an external filter. All materials meet UL94, V-0 flammability ratings.
