The THL 10WI is a series of general purpose 10 Watt dc/dc-converters packed in
the compact 1” x 1” case and is a pin to pin replacement for the popular 1” x 2”
size products. The industrial standard pinout, the ultra wide 4:1 input voltage range
and the input filter that meets EN 55022 Class A without external components make
these converters easy to design in and suitable for to cost optimize many existing
and new applications.
The models have a remote On/Off control, short circuit and overvoltage protection
and are applicable in temperature ranges of up to +75°C or +85°C with optional
mounted heat sink. Typical applications are instrumentation, distributed power ar-
chitectures in communication and industrial electronics.
