ABB ACS880-204LC liquid-cooled IGBT supply units

Capture and utilize braking energy in common DC bus drive systems, or support off-grid electricity distribution

By capturing and utilizing the braking energy, significant energy saving can be achieved. With ACS880-204LC’s regenerative functionality the braking energy is fed back to the network so that it can be utilized by other equipment. Built on our all-compatible architecture these liquid-cooled IGBT supply units are used in a common DC bus drive system to convert three-phase AC voltage to DC voltage.

The ACS880 modules come in two frame sizes: R7i and R8i. The ACS880-204LC is a modulating and fully controlled, active IGBT supply unit. Equipped with low harmonic LCL filters, the unit produces exceptionally low harmonic content and exceeds the requirements of even the most stringent harmonic recommendations. By managing and controlling harmonics, the unit reaches unity power factor. The line current is sinusoidal, and the DC voltage is constant.
