Chapter 4 – Twelve–Pulse Serial / Sequential Configurations with DCS 600
II F2
4 - 8 DCS 600 Manual for 12 – Pulse Operation
Measuring the DC voltage
(serial / sequential mode)
[continued]
Solution 1
:
SDCS-PIN-51
high-resistance
measurement
For Solution 1 the hardware coding of the voltage measurement
channels of the standard converters must be rescaled.
Note: This SDCS-PIN-51 modification (Solution 1) is possible up
to a rated supply voltage 500 V AC!
Complete 12 – pulse serial and sequential configurations
including units of the series DCA 600 enclosed con-
verters – as delivered from ABB – already feature the
required rescaling measures as an option.
