DC/DC Converter

TEN 8 Series 8 Watt

2 Year Product Warranty

The TEN 8 series DC/DC converter has been designed for a wide
range of space critical applications including tele- and data communi­cation systems and industrial process control systems. The shutdown
input feature makes these converters also ideal for mobile battery pow­ered equipment. High efficiency allows operation up to 71°C without
derating. Input filtering to EN 55022, class A and low output ripple

minimize design-in time and cost.
