PRODUCT OVERVIEW
FEATURES
High efficiency @ 12Vout, 92%
The UWE-Q12 series open frame DC-DC converters deliver up to 120 Watts in an industry-standard
eighth-brick through-hole package with a Vin range of 9-36Vdc. Standard fixed-output voltages
Up to 120 Watts total output power
include 5Vdc, 12Vdc and 24Vdc.
DOSA 1/8 brick pinout
The extended 4-to-1 input voltage range is ideal for applications that require a battery back-up,
telecom or portable applications. The modules can be configured with an optional baseplate for
cooling in the most demanding applications.
Over Temperature Protection (OTP)
The synchronous rectifier design uses the maximum available duty cycle for greatest efficiency and

hazardous materials compliance.
All units are precision assembled in a highly automated facility with ISO-traceable manufacturing
quality standards.
