ABB ACS 2000 air-cooled AC drive

The ACS 2000 air-cooled general-purpose AC drive is designed for reliability, easy installation and fast commissioning. The drive is specifically targeted at fan, pump, compressor and other common applications in industries such as water, cement, minerals and mining, metals, oil and gas, pulp and paper, power generation and chemical.

The drive is rated from 400 to 1,000 kVA in voltages up to 6.9 kV and is suitable for applications that do not require an engineered drive.

The drive can be used without an input isolation transformer, allowing a choice of direct connection to the line supply (direct-to-line). For applications where a voltage-matching input transformer is needed or galvanic isolation from the power supply is required, the it can be connected to a conventional two-winding oil or dry-type input isolation transformer.

With the active front end (AFE), line-side harmonics are minimised without the use of expensive, specialised transformers and requirements are met for current and voltage harmonic distortion stipulated in various standards. This avoids the need for harmonics analysis or the installation of network filters.

For minimal energy consumption, the AFE enables four-quadrant operation which feeds back braking energy into the line supply. The AFE can also provide reactive power (VAR) compensation so that a smooth network voltage profile can be maintained and reactive power penalties can be avoided.

Withdrawable phase modules allow easy front access to all drive components and provide quick replacement - resulting in a low MTTR.
