Help identify Varistor
Posted: Mon Feb 06, 2017 2:05 pm
I'm trying to understand how some old equipment from ABB is working. I have schematics for the circuit boards, but it do not contains any information about the parts. Can you please help me identify these varistors? The photo is attached.
This is off of an OLD VFD.
