TEN 20-2412WI TRACO Power

DC/DC Converters TEN 20WI Series, 20 Watt Features Ultra wide 4 : 1 input range Extended operating temperature range 40C to +85C I/O isolation 1500 VDC Input filter meets EN 55022, class A and FCC, Level A Remote On/Off Adjustable output Industry standard footprint Shielded metal case with insulated baseplate Optional heatsink Lead free design - RoHS compliant The TEN 20WI series is a family of high performance 20W DC/DC converter mod- 3-year product warranty ules featuring ultra wide 4:1 input voltage ranges in a compact 2 x 1.6 low prole fi package with industry-standard footprint. A very high efcfi iency allows an operat - ing temperature range of 40C to 85C. A built-in EMI input filter complies with EN 55022, class A. Further standard features include remote On/Off, output volt- age trimming, over voltage protection and short-circuit protection. Typical applications for these converters are battery operated equipment and dis- tributed power architectures in communication and industrial electronics, every- where where isolated, tightly regulated voltages are required.
