Harmonic Filters

Harmonic Filters
Schaffner is uniquely able to offer both passive harmonic filters and active harmonic filters for the efficient mitigation of mains harmonics, worldwide. Schaffner harmonic filters help to obtain compliance with international standards like IEEE 519-1992 and with local utility codes. They reduce the electrical and thermal stress upon the electrical infrastructure, eliminate the risk of harmonics-related reliability problems, and support long-term energy efficiency and cost savings.

Schaffner active and passive harmonic filters are UL listed and CE marked, ready for international use.
