DCS800 power converter modules

General

The power converter modules DCS800-S have the protection class IP00 and are to be mounted in a cubicle or finger protected area. There are different sizes (D1, D2, D3, D4, D5, D6, D7), graduated in terms of current and voltage ranges.

All units are equipped with the DCS800 Control Panel. It can be snapped into place on the power converter module or installed in the switchgear cubicle door by means of a mounting kit.

Accessories such as external fuses, line reactors etc. are also available, to complete the drive system.

Reference variables

The voltage characteristics are shown in the table beside. The DC voltage characteristics have been calculated using the fol lowing assumptions:

–UVN = rated input terminal voltage, 3-phase –Voltage tolerance ±10 % –Internal voltage drop approx. 1% –If a deviation or a voltage drop has to be taken into con sideration in compliance with IEC and VDE standards, the output voltage or the output current must be reduced by the actual factor according to the table on the right.

All converter modules up to 525 V and 1000 A (D1...D4) are equipped with field exciters. The power section of the converters is available as single   (2-Q) bridge or double (4-Q) bridge. 4-Q drives are required for regenerative breaking. 4-Q drives can be built by:

–Double (4-Q) armature bridge or –Single (2-Q) armature bridge plus a double (4-Q) field converter bridge 

 The bridge type has an influence on the maximum output voltage of the converter. See table below.

If armature voltages higher than recommended are requested, please check carefully, whether your system is still working under safe conditions. The maximum output voltage of a 4-Q drive can be increased up to the level of Udmax 2-Q. Thus the torque reversal from motoring mode to generating mode increases up to 300 ms. This lowers the dynamics of the drive and is only recommend ed for non-dynamic applications (e.g. E-Stop function).
