(1) Positive output terminal.
(2) Negative output terminal.
(3) Voltage signal for remote sensing: if you need remote sensing, connect the sensing wire from the positive end of your
load to this connector.
(4) Ground terminal.
(5) Connector for I/O pins: these pins are directly connected to some of the I/O pins of the Arduino Micro board. See 5-2
for more details.
(6) USB connector for Arduino Micro.
(7) RS485 Connector.
(8) Remote Sensing Enable/Disable: push this pin to enable or disable the remote sensing; when remote sensing is enabled,
RS will appear on the first line of the LCD Display, and the voltage shown is the actual voltage across load.
(9) Arduino Reset: push this pin to reset the Arduino Micro controller.
(10)
OV reset: push this pin to reset the power supply when it’s in over-voltage protection mode.
(11) AC voltage selection switch: use this to change the input AC voltage between 110V and 220V.
Before plugging the
power supply into the wall outlet, make sure that the AC selection switch shows the correct value in the middle, i.e.
