AHF – The Power Quality Controller!
AHF is the modern solution for improving power quality. Active filters AHF are used for compensation of harmonic currents and reactive currents in the phases and in the N conductor. For this purpose, the active filter injects harmonic currents into the supply grid which are in phase opposition to the harmonic currents of the load. In addition, the active filter can also be used for inductive and capacitive reactive current compensation and load current balancing between phases.
The Power Quality Controllers AHF offer significant advantages:
than conventional active filters built with silicon semiconductors (IGBT). This reduces installation and operating costs!
With the PRO units, you achieve the performance of modern active filters at the operating costs of low-loss passive filters.
