・All specifications are subject to change without notice.
For ±the 12V output model, output voltage can be set to
24V single output by making the COM terminal and TRM
terminal open. And output voltage can be set to 30V single
output by making the COM terminal open and connecting
the TRM terminal to the -Vout terminal.

1-3. Output voltage adjusting func-
Output voltage can be varied in the range shown in the fig-
ure below by connecting a resistance (Ra, Rb) between the
TRM terminal and the -Vout terminal or between the TRM
terminal and +Vout terminal.
Note that when the output voltage is set high, derating
of output current is necessary according to the maximum
power.
