DCS 600 Manual for 12 – Pulse Operation II F2 4 - 7
Measuring the DC
voltage (serial /
sequential mode)
Changes of the voltage measurement channel required for 12 –
pulse serial and sequential configurations:
The master converter has to measure the double DC voltage of the
original 6 – pulse DC voltage; for that reason the design of the high-
resistance voltage measurement circuit integrated in the units of the
series DCS 600 requires hardware changes of the internal voltage
measurement channel if the units are used in 12 – pulse serial and
sequential configurations.
Note: These hardware changes in connection with a 12 –
pulse serial and sequential configuration can only be
applied to the units DCS 600 of the sizes
C3 (900 A…2000A) with max. supply voltage 350 VAC
C4 (2050 A…5150A) with max. supply voltage 600 VAC
