In the same way, remote sensing wires can be connected
to load.
〈Example 3: Values and Method of Resistor and variable
For S type model with remote sensing terminal, the follow-
ing method can be used.
Variable resistor is attached as remote programming resis-
tor, and the output can be remotely programmed. Ratio of
remote programming resistor is basically 1V/kΩ.

2 -2 OUTPUT VOLTAGE RANGE 〈F type〉
The output voltage can be adjusted within -60 % - +20 %
(2V, 3V: ±20% ) of nominal voltage range. However, note
that OVP will be activated when output voltage is raised
over specification range.
Furthermore, when the output voltage is adjusted to high,
the output current shall be derated to a value that is pre-
scribed by the maximum output power. Also, when output
voltage is adjusted to high, there is a limitation on the in-
put voltage range for each model as shown in Figure2-5,
as well as limitation on the minimum output current as
shown in Figure 2-6 for each model.
