APPENDIX 1 - TPD32-EV-CU: CONTROL UNIT
General description
TheTPD32-EV-CU-…isanelectroniccontrolunitdesignedforusewithoneormoresix-pulsetwoorfour-
quadrantpowerbridgeSCRAC/DCconverters.Itissuppliedasastand-aloneunitforsystemsthatalreadyhave
apowerbridge.
Thecontrolunitregulatesthearmaturevoltageandcurrent,generatesSCRgatecommandsignalsandalsocon-
tainsa40Aor70Aeldpowersupplycircuit.Itissuitableforpowerbridgesconnectedtoa230VACto690
VAC50/60Hzthree-phasevoltagesupply.Itinterfacesdirectlywiththethree-phasepowerline,thearmature
voltageandarmaturecurrent,measuredbytwocurrenttransducersthatmustbeincludedonthepowerbridge.
Itcoversarmaturecurrentsrangingfrom4A
dcto20,000Adc.
