Unformatted text preview: tion e f 2.2 DCS 600 Power Converter Modules The power converter modules are modular in construction. They are based on the housing, which contains the
power section with the RC snubber circuit. There are
different sizes, depending on current and voltage. All
units are forced cooled.
The power section is controlled by the unit’s electronic
system, which is identical for the entire product range.
Parts of the unit’s electronic system can be installed in
the unit, depending on the particular application in- Reference variables
The voltage characteristics are shown
in Table 2.2/1. The DC voltage characteristics have been calculated using
the following assumptions:
• UVN = rated mains voltage, 3-phase
Voltage tolerance ±10 %
Internal voltage drop approx. 1%
If a deviation or a voltage drop has
to be taken into consideration in
compliance with IEC and VDE
standards, the output voltage or
the output current must be reduced by the actual factor according to table 2.2/1. System connection voltage

board to connect the converter to an overriding control
system. A control/display panel is available for the
operator. It can be mounted to the power converter
module or installed in the cabinet's door by means of a
Accessories such as external fuses, line reactors and the
like are available, for putting together a complete drive
system. DC voltage
