(1) Connect output of the external DC source to PV(PIN 26) and –V(PIN 24) on CN1, as shown in Figure3-1.
(2) Relationship between the output voltage and the external DC
is shown in Figure3-2.

(3) When increase the output to a higher voltage level, please reduce the load current accordingly. Output wattage of each unit should not
exceed the rated value under any circumstance.
