ACS880-207 IGBT supply units

Built on our all-compatible architecture these IGBT supply units are used in common DC bus drive systems to convert three-phase AC voltage to DC voltage.

Capture and utilize braking energy in common DC bus drive systems

Built on our all-compatible architecture these IGBT supply units are used in common DC bus drive systems to convert three-phase AC voltage to DC voltage. The IGBT supply units produce exceptionally low harmonic content and exceed the requirements set by low harmonic requirements. By managing and controlling harmonics, the ACS880-207 reaches unity power factor. The supply unit is able to boost output voltage to guarantee full motor voltage even when the supply voltage is below nominal. The supply unit also offers the possibility for network power factor correction to compensate for low power factors of equipment connected to the same network.

The supply unit consists of LCL line filters and R8i IGBT supply units, which are optimized for easy cabinet installation. It can operate in both motoring and generating modes.

Key benefits

IGBT supply units are used in regenerative drives to convert three-phase AC voltage to DC voltage. The ISU consists of R8i and LCL filter modules. It can operate in both motoring and generating modes.

Everything in one package

All the essential features are built-in as a stand alone drive.

Energy efficiency

Multidrives ordered with IGBT supply unit (ISU) which can regenerate the braking energy to the grid and also have very low harmonic content. ISU is very tolerable to network voltage variations.

Optimal grid control

The IGBT supply unit can be equipped with Optimal Grid Control functionality and it can work as a grid converter. A grid converter is used to produce an island AC grid.

Reduced harmonics

Total harmonic distortion typically <3% in nominal situation and undisturbed network. The control also provides a near unity power factor. The supply unit can also boost DC voltages e.g. when line voltage is low.

High power density

Achieves up to 6131 kVA with efficient heat dissipation, allowing greater power in a smaller footprint.

Superior thermal management

Ensures reliable performance in high-temperature, harsh industrial environments.

Flexibility

Suitable for multiple industries and can be integrated into various systems. ACS880 multidrives can be constructed into complex shapes to fit the space available.

Suitable for harsh environments

ACS880 drives are designed to operate in demanding industrial conditions. Customer can choose from IP22, IP42 and IP54 degree of protection.

Modular design

Scalable architecture for customized power solutions and easy expansion.

Connectivity

Supports a wide range of fieldbus protocols and I/O options.

Global compatibility

Global product approvals, e.g. CE, UL, cUL, CSA, marine certifications.
