TEN 40-4815WIN - 

Traco 40W Single/Dual Output Regulated Isolated DC-DC Converter - TEN-40WIN Serie
The Tracopower TEN 40WIN Series is a new range of isolated high performance DC/DC converters. Due to the very high efficiency of up to 90% these 40 W converters come with a very small footprint. The TEN 40WIN has an ultra wide 4:1 input voltage range and a tight output voltage regulation. The output voltage is adjustable by external resistor. Remote On/Off and protection against overpower and over voltage are standard features of these converters. Typical applications for the TEN 40WIN DC/DC converters are in mobile equipment, instrumentation, distributed power architectures in communication and industrial electronics and everywhere where space on the PCB is limited.
