TDR 2-1211WISM TRACO Power

DC/DC Converter TDR 2WI Series, 2 Watt Compact design in THD Package Ultra wide 4:1 input voltage range Fully regulated outputs Low ripple and noise Temperature range 40C to +85C without derating UL 62368-1 IEC 62368-1 UL 60950-1 IEC 60950-1 I/O isolation 1600 VDC The TDR 2WI series is a family of compact 2 W DC/DC-converters with 4:1 in- Continuous short-circuit protection put voltage ranges and tightly regulated output voltages even under no load Remote On/Off control conditions. The product is available in THD-package. They work with high effi- ciency over the full load range and come with a remote On/Off input. The us- Fully RoHS compliant ability in temperature ranges of up to 85C without power derating, continuous 3-year product warranty short circuit protection and excellent immunity against environmental influ- ences make these converters very reliable. A TDR 2WI converter is the ideal so- lution for space critical high end applications in communication equipment, in- strumentation and industrial electronics.
