AVC118 has been integrated an isolated arc voltage
divider, the divided ratio is 1:100. The arc voltage sense
wires should be at least 0.9 mm squared twisted pair
wire, rated 600V or greater. When connecting arc
voltage sense wires to the controller, please check the
arc voltage polarity carefully to ensure correct
connection, otherwise serious damage may occur.
