UL 60950-1
The TDR-3WI series is a family of compact 3 W dc/dc-converters with 4:1 input
voltage ranges and tightly regulated output voltages even under no load conditions.
The product is available in SMD-package or in DIP-package. They work with high
efficiency over the full load range and come with a remote On/Off input.
The usability in temperature ranges of up to +85°C, continuous short circuit protection and excellent immunity against environmental influences make these converters
very reliable.
A TDR-3WI converter is the ideal solution for space critical high end applications in
communication equipment, instrumentation and industrial electronics.
