The TEM03 series offer 3 watts of output power from a 1.12 x 0.81 x 0.33 inch package
without derating to 50
ºC
and without external input/output capacitor. The TEM03 series with
2:1 wide input voltage of 4.5-9, 9-18, 18-36 and 36-75VDC and features 500VAC of
solation, short-circuit protection. The safety meets to EN60950 and UL1950. All models are
particularly suited to telecommunications, industrial, mobile telecom and test equipment
applications.

The follow output voltage can be outputted by connecting this terminal to an output + or – terminal. Unless the output voltage is adjusted, this terminal
should be open.
In addition, the voltage can be adjusted not by shorting these terminals, but by connecting them to resistances as shown below.
Arithmetic expression connected resistance: R ( K )
3-1 Vo=(3.3*R+36.7)/(R+10)
3-2 Vo=(3.3*R+36.7)/(R+12.92)
