Reversed Connection of Input
Reverse (-, + electrodes) connection of the input may
cause damage to the power module. Whenever there is
a possibility for a reverse input connection, attach a pro-
tective diode and an input fuse. The rated voltage of the
protective diode shall be higher than input voltage, and the
maximum in-rush current shall be higher than external fuse
rating.
2  -1 OUTPUT VOLTAGE RANGE 〈S type〉
Output voltage can be adjusted within ±10% of the nomi-
nal voltage by adjusting the external trimmer (variable resis-
tor). However, note that OVP (Over Voltage Protection) will
be activated when the output voltage is raised over specifi-
cation 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 input
voltage range for each model as shown in Figure2-1.
Values and connection methods of external resistors and
variable resistor (VR) are shown as follows.
