Line Impedance Stabilization Networks
Three-Phase LISN 2X Series

Built for commercial AC power line conducted-emission testing under global EMI/EMC standards, the 2X series delivers a stable, 50 Ω / (50/250 µH +5 Ω) network and full isolation for accurate noise measurements.

The LI-3P-2X series of three-phase Line Impedance Stabilization Networks is engineered for power-line conducted emissions measurements from 9 kHz to 30 MHz, fully compliant with CISPR 16-1-2 and ANSI C63.4 across all four models. The series spans a range of current capabilities—from 16 A to 100 A continuous per line—to accommodate everything from low-power three-phase devices to demanding industrial equipment. Each LISN incorporates a standardized four-conductor, 50 Ω / 50-250 µH + 5 Ω network, ensuring the defined impedance, isolation, and measurement consistency required for commercial EMC testing. All models include remote line switching, air-core inductors to avoid saturation under load, and an integrated transient limiter to protect the RF measurement instrument during testing.

LI-3P-2100 — Heavy-Industrial 100 A LISN:

Ideal for large three-phase machinery, EV chargers, industrial drives, high-capacity inverters, and any equipment drawing substantial continuous current. Its 100 A rating supports testing without requiring external current-limiting hardware, making it essential for labs working with full-scale operational loads.

LI-3P-263 — Mid-Range 63 A LISN with Active Cooling:

Designed for standard commercial three-phase equipment, such as smaller drives, pumps, compact UPS systems, CNC tools, and industrial control panels. Its lighter weight and simpler thermal design make it ideal for labs with frequent repositioning or mixed-device throughput.

LI-3P-232 — General-Purpose 32 A LISN:

LI-3P-216 — Low-Power 16 A LISN for Smaller 3-Phase Devices:

Intended for testing low-current three-phase appliances, compact industrial modules, lab instrumentation, and pilot-scale prototypes. Its compact footprint is valuable where bench space is limited or when evaluating early-stage designs that do not require higher-current capability.
