Traco 200W Single Output Regulated Isolated DC-DC Converter - TEQ-200 Series
The Tracopower TEQ-200WIR series of isolated, high performance DC-DC converters come with ultra-wide 4:1 input voltage range in a rugged, sealed metal case. These converters can be used with a temperature up to 70°C with natural convection cooling and up to 90°C with power derating. The TEQ-200WIR features output voltage trimming, remote ON/OFF and under voltage lockout. These DC-DC converters are suitable for a wide range of applications, including railway and battery operated systems, but they are particularly designed for industrial applications where no PCB mounting is possible and the module has to be mounted on chassis.
