DC/DC Converter TEN 25 Series 25/30 Watt Features pending Wide 2 : 1 Input Range Very High Efficiency up to 89% Operating Temp. Range – 40°C to +71°C Continuous Short-Circuit Protection Over Voltage Protection I/O-Isolation 1500 VDC Input Filter meets EN 55022, Class A and FCC, Level A without external Components Industry Standard Pinout Low Profile Six-side Shielded Metal Case with insulated Baseplate 2 Year Product Warranty The TEN 25 series is a new range of isolated DC/DC converters with high power density in a 50x40x9.3mm shielded metal case. All 18 mod- els have a wide 2:1 input voltage range. The very high efficiency allows a safe operating temperature range of -40°C to +71°C. Other features are internal EMI-filter to meet EN55022, classA and Remote ON/OFF. Typical applications for these converter modules are industrial electron- ics, communication systems, battery operated equipment and distributed power systems.
