ABB ACS 5000 MEDIUM VOLTAGE DRIVES

ABB ACS 5000 MEDIUM VOLTAGE DRIVES

DESCRIPTION

The ACS 5000 provides speed or torque control for motordriven applications in the medium and high power range from  1.5 to 36 MW at motor voltages from 6.0 to 6.9 kV. It is available with air cooling in the lower power range and with water  cooling in the medium to high power range.

The compact air-cooled ACS 5000 is a general purpose drive  designed to control standard motors, typically used for applications such as pumps, fans, compressors, mixers, mills and  conveyors. The high-power water-cooled ACS 5000 provides  reliable motor control for high power, high speed or special  performance applications such as large pumps, fans, extruders,  compressors and SAG and ball mills.

The ACS 5000 is supplied with separate or integrated input  isolation transformer.

Proven solution for a wide range of industries

Since its market introduction in 2005 the ACS 5000 has  provided reliable and efficient control of medium voltage  applications in a wide range of industries.

IGCT semiconductors

The ACS 5000 uses a power semiconductor known as IGCT  (Integrated Gate Commutated Thyristor), which is an ideal  switch for high-powered medium voltage applications. The  use of IGCTs results in low parts count, providing an efficient  and reliable drive.

High level of personal safety

Electric arcs represent a hazard source for people and goods.  For systems where large and dangerous arc fault currents can  occur, special attention is required. Therefore, the high-power  water-cooled ACS 5000 is equipped with a superior protection  function and ABB’s Arc Guard SystemTM. This IAC classified  solution assures very fast arc detection and elimination (less  than 6 ms) to protect people and equipment and eliminate  unnecessary production stops.
