ABB 3BHE009949R0003 UNS4881BV3AVR unit (COB+MUB) assembly

DCS800 DC Drive Promises

The drive meets the requirements of the most demanding drive applications. 

Embedded software functions offer upgrades to all classic installations like 12-pulse, double motor operation, and field reversal.

Highlights

− Reduced installation and commissioning work

− Internal three phase field exciter without additional external hardware (D1-D5)

− Excellent control performance up to highest dynamic application in field weakening operation

− All ACS800 PC tools (via DDCS) can be connected

− Able to be customized to your needs with Adaptive programming and with option Control Builder

− Flexible fieldbus system with built-in Modbus and numerous internally mountable fieldbus adapters

− Virtually all DCS800 component parts are suitable for recy cling.

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 amounting kit. 

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

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.

Reference variables

The voltage characteristics are shown in the table beside. The DC voltage haracteristics have been calculated using the following 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 consideration 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.
