Use the numeric keys (
0
~
9
) or “Rotary” (
) to set the EXTERNAL
ON/OFF mode. This function has two selections, DISABLE and ENABLE.
1.
Selecting DISABLE:
It closes this function.
2.
Selecting ENABLE:
It sets EXTERNAL ON/OFF to ENABLE and make the
“
ON/OFF
” invalid, also the Pin22 (_EXT_ON) replaces the
“
ON/OFF
” to control the Power Supply’s ON/OFF. When
Pin22 (_EXT_ON) voltage level of the ANALOG
INTERFACE turns to HIGH, the Power Supply is unable
to output, that is OUTPUT = OFF. When Pin22
(_EXT_ON) voltage level turns to LOW, the DC Power
Supply outputs normally, that is OUTPUT = ON.
