The TMDC 20 Series is a range of encapsulated high performance DC/DC converter
modules. With a very high efficiency of up to 91% and the use of highest grade com-
ponents 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 efficiency also at
low load conditions. They feature a remote control input and a green power good
LED which indicates the presence of the output voltage. Protection against overload
and short circuit are standard features of these converters. EMC characteristics and
safety certifications are aligned for the operation in industrial environment.
