PMM L3-500 LISN

3Ø, 9 kHz - 30 MHz, 500 A, 690VAC

The PMM L3-500 LISN tests 3-phase power AC circuits up to 60Hz within a frequency range of 9kHz - 30MHz. It is suitable for a wide range of industrial and regulatory testing scenarios with its substantial current handling capability, continuous operations at 300A, and peak performance up to 500A for brief periods. This device is effective for measuring conducted interference because of its three-line plus neutral V-network that has an equivalent circuit of 50Ω // (5Ω + 50μH).
