Power supply
#2 is a current transformer. The wires cut off at the top were the
output sensing connectors. Maybe two sets - to a meter and to a controller. It appears that power comes in from the right - through fuses ? goes through a contactor and fires up the three phase transformer. The secondary of the three phase transformer is sent to the bridge of Thyristors - Likely SCR's the small wire are the control gate and a reference wire. That is a great mount of power being rectified there. Martin Martin H.

After stripping everything not needed away I ended up with this: http://www.metalworking.com/dropbox/supply1.jpg http://www.metalworking.com/dropbox/supply2.jpg A few questions. Each of the twelve diodes has a pair of wires, 24 connections on the terminal strip. I don't know the function here and if anything needs to be connected. Is the part labeled 1 an isolation transformer? If so, should DC- be grounded? Can the part labeled 2 be used to read current? There are four leads, how would they be connected. The part says "Nana Electronics NNC-05AF" Karl |
