Schaffner has launched a new family of EMC and EMI filters for photovoltaic systems from 250A and 2,300A.
With the approval of the latest CISPR11, Ed.6.0 international standard, which now defines the conducted emission limits at the DC power ports of “Grid Connected Power Conditioners”, EMC/EMI filters on the AC and DC side of inverters and converters contribute significantly to compliance with the EMC directive. They can also improve system reliability, and the the FN221x HV and FN331x HV filters are optimized for the requirements of photovoltaic, power conversion, energy storage and motor control systems.
The filters are aimed at high current applications for 690 VAC and 1,500 VDC PV inverters, converters and motor drives. Together with appropriately sized 690 VAC FN 331x HV filter on the line side, the new FN 221x HV DC filters help to meet the limits of EMC standards for PV installations in Europe and other regions. The 1500 VDC filter FN 221x HV also helps to increase the service life of the solar panel, improve its reliability, and reduces potential interference radiations of the panel by filtering high-frequency and leakage currents from the inverter.
