Power Quality Products


Talking about power quality, one very often thinks of harmonics, voltage fluctuations and interruptions, flicker, commutation notches and further phenomena on the mains power line side. 
The Schaffner view of power quality goes beyond and also focuses on solutions for the equipment side, in particular for the output side of motor drives and inverters.

Harmonic Filter

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.

Line Filters and Reactors

Line Filters and Reactors

Line filters and reactors, also operated on the line side of power drive systems, efficiently proetct inverters electronics and dc link capacitors from inrush, peak and short-circuit currents, Additionally, low-frequency interference and harmonics are reduced significantly.

Output Filters and Reactors

Output Filters and Reactors
Output filters and reactors for motor protection and the improvement of system reliability, availability and functionality. Deployed at the output side of frequency inverters, these components ensure reliable operation by avoiding expensive downtimes of installations, manufacturing plants, machinery and a vast array of other industrial and domestic motor drive applications due to premature motor damage. An appropriate output solution will even allow the deployment of unshielded motor cables, the use of multiple motors in parallel on the same drive or the retrofit of modern drives in existing installations with old motors and unshielded cabling.
