The TMDC 20 Series is a range of encapsulated high performance DC/DC con-

verter modules. With a very high efﬁciency of up to 91% and the use of highest

grade components these 20 W converters are made for a reliable operation in the

temperature range of -40°C up to 90°C. They come in chassis mount version with

screw terminal block. The 8 models have a wide 4:1 input voltage range and a tight

output voltage regulation. They do not need a minimum load and offer a high efﬁ-

ciency also at low load conditions. They feature a remote control input while a green

LED indicates the presence of the output voltage. EMC characteristics and safety

certiﬁcations are aligned for the operation in industrial and residential environment.
