1,1600AF stationary mount molded case switch,with UV trip and auxiliary contacts.
2,Ammeter 0-2000ADC
3,Voltmeter 0-1000VDC
4,SCR ‘’ON’’indicating lamp
5,6-pulse,1800ADC,750VDC vertical air cooled bridges,Each bridge is protected with two 600A SCR fuses per SCR.On each pair of fuses there is a micro switch that is opened to indicate the fuses have opened.This switch also takes the SCR bridge off line.
6,A surge suppression’’ON’’lamp.Surge protection is provided for each SCR bridge.Surge suppression is provided by a fused set of Metal Oxide Varisors(MOVs).The MOVs clamp any voltage spikes in the bridge that may be damaging to the SCR pucks.
