15 Watt

Single and Dual Output, 4:1 Input Range, 1.25” X 0.80 “ X 0.40 DIP Package


DC-DC Converters for Industrial Applications

Our TWB15 series of DC-DC converters features 15-W regulated and isolated outputs, as well as 1,600-Vdc isolation voltage, low standby power and no minimum load requirement. Equipped with an internal EN55032 Class A filter, each unit includes overcurrent, undervoltage and short circuit protection—all in a 24 DIP package. The series meets UL 60950-1, EN 60950-1 and IEC 60950-1 approvals.
