ACS800-11 - regenerative wall-mounted single drives

 

ABB regenerative drives save energy and reduce panel size.

 

An ABB ACS800 regenerative drive offers significant energy savings compared with other braking methods such as mechanical and resistor braking, as energy is fed back to the AC line network.

 

To stop quickly stop a motor fitted with an inverter drive, dynamic braking is often used.  This involves applying a braking torque to the motor to bring it to a stop.  The energy released during this process is normally absorbed by a braking circuit and dissipated through braking resistors in the form of heat, to protecting the drive from overloading.

 

Feeding the energy generated by braking back into the power supply generates much less heat than a braking resistor; reduces power consumption.  Installation is simplified and space requirements reduced by eliminating the need for cooling hardware.

 

High performance

The ABB ACS800 regenerative drives are especially suitable for demanding industrial applications. Transition between motoring and generating is fast due to the DTC control method.

 

The active supply unit is able to boost output voltage, which guarantees full motor voltage even when the supply voltage is below nominal. The active supply unit combined with DTC control can even compensate for fast variations in line voltage. There is no risk of fuse blow or component damage due to voltage drops in the network.

 

Energy savings.

The regenerative drive offers significant energy savings compared with other braking methods such as mechanical and resistor braking, as energy is fed back to the supply network. The energy fed back into the supply can also be used for other purposes, reducing operating costs still further.

 

These wall-mounted regenerative single drives save you more space and energy. Plus they allow full power flow in both motor and generating modes. A wide range of built-in features and options give you optimal solutions for different applications.
