The QBC-12/22-L48 DC/DC converter is one of DATEL’s new generation, fully

isolated, Intermediate Bus Converters, designed and optimized for total on-board

solutions in combination with our non-isolated point of load converters of the HEN,

LEN, LQN, LSM and LSN series.

The QBC’s convert the standard 48V (40.5 to 57V limited range) to a non-

regulated 12V (9.6 to 13.5V range) bus voltage with a total output power of 264

Watts. Taking full advantage of a synchronous-rectiﬁer topology, the QBC-series

achieve ultra-high efﬁciency of 96%, minimizing power losses and enabling full-power

operation to ambient temperatures up to +70°C with minimal air ﬂow.

These high-density, open-frame DC/DC converters are standard quarter-brick

packages with industry-standard footprint and are only 0.42 inches (10.67mm) high,

or 0.54 inches (13.72mm) with optional heat sink.

Assembled using fully automated, SMT-on-pcb techniques, QBC’s provide ﬁxed

frequency conversion, output On/Off control with choice of positive (standard) or

negative (optional) logic, stable no-load operation, current sharing capability, and low

output ripple/noise (80mVp-p).

The fully functional QBC bus converters feature full I/O fault protection including

input overvoltage and undervoltage shutdown, output overvoltage, output current

limiting, with choice of "hiccup" (standard) or "latching" (optional), short-circuit protec-

tion, and thermal shutdown.

All models are IEC/EN/UL60950 certiﬁed and EMC compliant. Safety, CB, HALT

and EMC reports are available upon request.
