The TMDC 40 Series is a range of encapsulated high performance DC/DC con-

verter modules. With a very high efﬁciency of up to 92% and the use of high-

est reliable components these 40 W converters are avialable as a chassis-

mount with screw terminlas or PCB versions. 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.

Remote On/Off and protection against overload and short circuit are standard

features of these converters.
