ACS 5000 – making a difference The evolution of ABB’s ACS drives platform for motors up to 6.9 kV has led to a drive with unbeatable efficiency, reliability and footprint. Leading the way As the originator of AC drives technology, ABB has over 35 years of application know-how in all industrial sectors. ABB knowns how to convert customer requirements into reliable world-class products, which fulfill customer's future needs. The ACS 5000, the latest member of the world’s most successful drives family, confirms ABB’s market leadership. Revolution by evolution The ACS 5000 is based on ABB’s renowned ACS platform, that has been used in thousands of drives worldwide.

The combination of well- proven building blocks from existing ABB medium voltage drive products with the Voltage Source Inverter Multilevel-Fuseless (VSI-MF) topology, has revolutionized the drives industry – it simplifies the drive, increases its reliability and efficiency and results in the most application-friendly high- power drive available on the market. The ACS 5000 was developed to specifically meet the requirements of the growing number of applications driven by standard motors up to 6.9 kV. ABB ACS 5000 - 3 Benefits:

ACS 5000 – Highest performance and lowest cost of ownership ABB engineers developed a drive that provides advantages over other medium voltage drives in reliability, efficiency and power density - features that have a direct impact on the customer’s cost of ownership. Highest reliability and efficiency Thanks to the combination of well-proven components and an innovative topology, the ACS 5000 has a reliability and efficiency unmatched on the market. IGCT semiconductors T he ACS 5000 uses an advanced and proven power semiconductor switching device known as IGCT. It combines the best of two traditional semiconductor technologies:

the fast switching of the IGBT/IEGT with the proven reliability and low losses of the GTO. Fuseless The converter design does not require any medium voltage power fuses, which are known to be unreliable, costly and subject to aging. Instead of fuses the ACS 5000 uses IGCTs/thyristors, which provide much faster and more reliable protection for the power components. The ACS 5000 protection scheme responds in less than 25 µsec, about two hundred times faster than fuses. The use of IGCTs results in a low parts count, providing an intrinsically less complex, more efficient and reliable drive.

Long-life DC-link capacitors Advanced, self-healing, environmental friendly foil capacitors, designed for a long lifetime, are used in the DC-link. ABB has clearly distinguished itself with this technology compared to unreliable and maintenance- intensive designs based on electrolytic DC-link capacitors.

Powerful and application-friendly During development of the ACS 5000, special attention was given to the entire drive system to provide highest configuration flexibility and ensure powerful and application-friendly performance. Smallest footprint The ACS 5000 is based on a unique concept which enables operation of motors up to 6.9 kV without making the drive more complex. Thanks to the Voltage Source Inverter Multilevel- Fuseless (VSI-MF) topology the high motor voltage is achieved without series connection of semiconductors.

This reduces the parts count to a minimum resulting in a power density up to 1 MVA/m 3 for the complete drive, including control, cooling and auxiliaries, which is un- matched in the medium voltage drives market. Powerful performance Fast and accurate process control in combination with low energy consumption results in top performance. The ACS drive control platform is ABB’s award-winning Direct Torque Control (DTC), resulting in the highest torque and speed performance as well as the lowest losses ever achieved in medium voltage drives.

Control of the drive is immediate and smooth under all conditions and the audible noise in the motor is considerably reduced compared to other control methods. Motor friendly The ACS 5000 topology has an optimum number of switching levels, which provides a multilevel output waveform. This allows the use of standard motors up to 6.9 kV without compromising reliability. Transformer flexibility For highest transformer flexibility, the air-cooled ACS 5000 is available with a separate input transformer or, in the lower power range, with an integrated input transformer. Network friendly The ACS 5000 is equipped with a 36-pulse diode rectifier to minimize harmonics.

It meets the most stringent requirements for current and voltage harmonic distortion as defined by IEEE, IEC and EN. This eliminates the need for costly harmonics analysis or installation of network filters when applying a new drive. The integrated input transformer allows simple and quick installation and commissioning , whereas the separate transformer permits a flexible transformer configuration. Depending on the customer’s infrastructure, the transformer can be placed either inside or outside the electrical room. ABB ACS 5000 -
