Rated characteristics of ABB DC series DCS550 digital drives

The input voltage of the electric drive is 3x220-525V 50Hz

Ia is the rated output current of the drive, Iexc is the rated current of the excitation circuit, Pn is the rated power of the electric drive.

ABB DCS550 Digital Electric drives

Over the years, ABB has earned a high reputation and the respect of numerous customers. It is the undisputed leader in the market of electric power and automated technologies. The history of the company began 120 years ago, although the company received its modern name only in 1988. The result of the activities of its employees has become a long list of created and patented innovations that are in demand and used everywhere in all corners of the world.

Today, the company produces generators, engines, ABB electric drives and other similar products.

ABB DCS550 DC Drive: Product Description

Each control board and all working elements have received new, improved insulation, which allows them to avoid contact with air currents, dust particles and other environmental aggressors. Thanks to a completely redesigned device design, ABB electric drives They are able to work in the most difficult conditions: in polluted, dusty rooms, outdoors, etc.

Now equipment modernization is possible without any additional costs (both time and finance), because all modern drives easily replace any devices of an earlier year of manufacture. A universal, intuitive control panel is available as standard and the conditions for working with DC motors of all types and configurations are met. In addition, the DCS550 DC regulator is available for combination with Drive Window Light, Drive Window LightAP, etc. programs.

Technical specifications

The equipment has 7 analog and 8 digital inputs for connecting additional devices.

The rated armature current is considered to be from 20 to 1000 A, and the rated voltage is 220 /525V ± 10%.

The improved protection system makes it possible to safely operate electric drives in absolutely any conditions, including under constant increased loads or under conditions of exposure to an aggressive environment.

Scope of application

The DCS550 DC drive has been designed to meet the requirements of installations with high dynamic performance and overload capabilities, small dimensions and simple operation. These can be:

• the extruder;
• The centrifuge;
• printing press;
• press;
• insulation installation;
• machines, etc.
