ABB SPAD346C Transformer Generator Differential Protection Relay
The DCV 700 series is a complete range of DC converters intended for the
supply and control of DC machines, in stand-alone or multi-drive systems
with high performance and reliability specifications.
Wide Variety of Industrial
Applications
The DCV 700 series can handle the most demand ing applications in:
• rolling mills
• pulp and paper
• metals (casters, processing lines etc.)
• material handling (cranes, hoists etc.)
Digital Control
To meet the most stringent control requirements,
the DCV 700 features speed control, which re duces the effects from gear backlash and torsional
vibration arising in mechanical systems.
High-performance speed and torque control will
fulfill all requirements for rapid response and
control accuracy. Autotuning for armature cur rent control will simplify the commissioning
procedure.
DCV 700 converters are fully digital and mounted
in an enclosure complete with all necessary
equipment, meeting the most stringent safety
standards. The converter can be used for stand ard applications but has the flexibility to be
customized for the most demanding applica tions.
Comprehensive Product Range
DCV 700 converters are available as 6-/ and 12-
pulse 2- or 4-quadrant, in a current range 22 to
5150/10300 A and supply voltages of 200 to 1000
VAC. A selection of options is available to provide
the user with a system meeting the most demand ing technical requirements and performance ex pectations.
Common control electronics throughout the range
reduces spare parts inventory and training re quirements.
