Novaris 0038-I1V1 SFH high-current surge filter

The Novaris SFH series of high-current surge filters is suited to high-power RF transmission sites, where there is not enough power cabling distance within the control building to allow for a multistage protection approach.

The series contains two stages of fail-safe surge protection to create redundancy. These two stages are separated by a low-pass LC filter that emulates a large cable length, enabling surge protection coordination. The low-pass filter also has the added benefit of EMI, RFI and surge frequency filtering. The combination of these components creates a robust surge protection system and provides a low let-through voltage.

The series is available in 250 to 2000 A configurations with up to 200 kA of front-end protection.
