15 Watt

2:1 Input Range, 1.25" x 0.8" x 0.40" Package


TWA15 Series DC/DC Converters Ideal for Industrial Applications

The TWA15 Series of isolated 2:1 input range 15-watt DC-DC converters for industrial applications come in a small 1.25 by 0.8 by 0.40-inch package. These devices do not require a minimum load, and they offer high efficiency up to 91 percent, 1,600V DC isolation voltage and remote ON/OFF control for energy savings. Built-in safeguards include over current, over voltage and short circuit protections. TWA15 Series converters come with a built-in EN 55032 Class A EMI filter, meet IEC/UL/EN60950-1 as well as UL 62368 standards, and they comply with RoHS and REACH directives.
