Power-One Intros QTS48T38096 DC-DC Quarter Brick

Power-One Inc. (Camarillo, CA) introduced its QTS48T38096, a 97% efficient, 38 A, dc-dc quarter-brick optimized for IBA bus converter applications. The industry-leading efficiency combined with a heavy-copper, multi-layer circuit board provides minimal temperature derating. At 70 °C ambient with only 200 LFM airflow, the QTS48T38096 delivers 34 A.

The QTS48T38096 operates from a regulated input of 36 Vdc to 55 Vdc to provide a 5:1 fixed-ratio output (9.6 Vdc output with a 48 Vdc input) and can deliver up to 418 W with a 55 Vdc input. The single-board, open-frame QTS48T38096 also features a 0.5 in low profile, 1,500 Vdc input-to-output isolation, remote ON/OFF, no minimum-load operation, and a parallel-operation option. Protection features include output over-current, input under-voltage lockout and input over-voltage shutdown.

Regulatory agency approvals include UL60950-1/CAN/CSA-C22.2 No. 60950-1-03, TUV EN60950-1, and IEC60950-1. Pricing is $40 each in quantities of 1,000. Evaluation units are usually available from stock. Production quantities are typically available in six to eight weeks.
