26. November 2018 - Schaefer has introduced the liquid-cooled PBAF 690-560 filter for activated high-voltage and high-current harmonics. Designed for oil rigs and 600V AC power grids, as well as for automation, wind turbine, and other industrial applications where harmonic removal is critical.
The filter provides harmonic suppression regardless of the number of loads and corrects for this power factor. 140A AHF pluggable modules (4 per system) = 560A per cabinet and each filter module has its own complete control system.
The PBAF series monitors the current signal and compensates for the unwanted elements of the measured current. The protection class of the system complies with the protection class IP65 and the safety and construction standards meet the standards EN 50178, IEC 62477-1, EN61800-3 (C2) and UL508. EMI according to EN 61000-6-4.
