The TEN 8WI series is a family of high performance 8W DC/DC converter modules featuring ultra wide 4:1 input voltage ranges in a DIP-24 package with industry-standard footprint. A very high efficiency allows an operating temperature range of -40C to +85C. Full SMD-design with exclusive use of ceramic capacitors guarantees a high reliability and long product lifetime. Further standard features include remote On/Off, over voltage protection, under voltage lockout and short circuit protection. Typical applications for these converters are battery operated equipment, instrumentation, communication and industrial electronics, everywhere where isolated, tightly regulated voltages are required.
