15WI/20WI/30WI DC/DC Converter Modules

TRACO Power 15WI/20WI/30WI DC/DC Converters Modules are high-performance DC/DC converters designed with the highest power density. These converter modules are available in 15W, 20W, and 30W variants that are encapsulated in a metal case with dimensions of 1.0" x 1.0" x 0.4". The 15WI/20WI/30WI DC/DC converters modules from TRACO Power have an ultra-wide 4:1 input voltage range and precisely regulated output voltages. The advanced circuit design provides high-efficiency and makes the converter modules more reliable and applicable in temperature ranges of up to +85°C.
