Applications
Especially for applications in the low frequency range
from 150 kHz to 30 MHz
Perfect for applications with varying cable diameter
Reusable because of the key technology therefore
perfect for test and measuring purposes and cables
with difficult access
Suppression of electronic ballasts (i.e. neon tube) in
the lighting industry
