ACS880-37LC, liquid cooled cabinet-built ultra-low harmonic single drives

Manage and control low harmonics

The ACS880-37LC liquid-cooled drives with direct liquid cooling and robust design are an ultimate solution for various applications where space savings, silent operation or durability in harsh environments is a must. Since the liquid cooling takes care of 98% of the heat losses, no additional filtered air-cooling is needed. The drive cabinets are totally enclosed with high protection class.

Our all-compatible ultra-low harmonic drives create less harmonics compared to drives with standard diode supply solutions.The very compact ACS880-37LC produces exceptionally low harmonic content in the drives input. This is achieved without external filters or multi-pulse transformers. By managing and controlling harmonics, the ACS880-37LC reaches unity power factor. The active supply unit in the drive is able to boost output voltage, which guarantees full motor voltage even when the supply voltage is below nominal.
