Common Rectifier Operating instructions
The compliance voltage at the rated output current is 10V.
The transformation ratio of the current transformers is 2000 : 1
Source resistance R
i total
as per table.
NOTE
When measuring equipment is connected to the unit, the effective load impedance and thus the voltage will
vary in accordance with the internal resistance of the equipment.
For the lowest rated output current of 41A, all the jumpers (J1 to J14) should be open. For the maximum rated
output current with units Sizes B and C, 94A, jumpers J1 to J3 should be closed and J4 to J14 open.
Example: For a unit with a rated output current of 86A, jumper J3 should be open.
The units are dispatched from the factory with the jumpers (J1 to J3) on the board 6SE7028-8FC85-0OA0
closed. Before start-up the unit, therefore, the jumpers should be positioned as appropriate to the rated output
current (see rating plate) and accordance with Table 9.6.
