Mastertig 3500 AC/DC Z002
The filter cards Z001 (2000) and Z002 (2500/3500) have overvoltage protection against low
energy voltage spikes coming from the net, an EMI-filter against electromagnetic disturbances
conducting to the net and net overvoltage watch. Chokes L005 (2000) and L006 (2500/3500)
also limit the electromagnetic disturbances conducting to the net. Auxiliary transformer T002
generates the needed voltages for control cards.
