DC/DC Converters TEN 20WI Series, 20 Watt Features ◆ Ultra wide 4 : 1 input range ◆ Extended operating temperature range –40°C to +85°C ◆ 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 profile package with industry-standard footprint. A very high efficiency allows an operat- ing temperature range of –40°C to 85°C. 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.
