Arc Voltage divider installation size

Plasma Arc Voltage is divided by Arc Voltage Divider (offered with THC) on 50:1 via none isolate

voltage divide, lead into THC after processed by Isolation Circuit. It can be installed inside of the plasma

or cnc control cabinet. (

must use the shield cables

)
