High current EMC/EMI filters for 690 VAC or 1,500 VDC applications
With a combination of innovative component technology and design to deliver EMC solutions between 250A and 2,300A, Schaffner’s FN 22 xxHV and FN 33xx HV standard filters are aimed at high current applications for 690 VAC and 1,500 VDC PV inverters, converters and motor drives.
These filters are optimised for photovoltaic, power conversion, energy storage and motor control systems requirements and take into consideration Schaffner’s experience with AC and DC power systems.
Together with appropriately sized 690 VAC EMC/EMI filters FN 331x HV 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.
In addition, the 1,500 VDC filter FN 221x HV is said by the company to help increase the service life of the solar panel, improve its reliability and reduce potential interference radiations of the panel by keeping away the inverter-born high-frequency and leakage currents.
The compact AC filters FN 331x help to meet the EMC standards and are optimised to suit the latest inverter design requirements of various types of power converters.
The new filters are said to need less installation space than traditional solutions owing to the optimised attenuation performance levels. They also offer minimum power loss related to the inverter rating and help maximise system efficiency.
Both bus-bar filter series are available with ratings from 250 A to 2,300 A. Versions without capacitors to ground are also available as standard product for specific AC and DC power system requirements.
All models are CE, UL, CSA and ENEC (FN 331x HV) approved and RoHS compliant.
