LI-1100C

High-current 100 A single-phase LISN, 150 kHz to 30 MHz — the highest current rating in the 1x series and the standard choice for industrial, three-phase commercial, and heavy-duty single-phase products requiring CISPR 16-1-2 / ANSI C63.4 conducted emissions testing.

▸Separately housed single-conductor networks with SUPERCON® shrouded sockets — one 50 µH air-core network per current-carrying conductor allows flexible installation in single-phase, dual-phase, DC, and three-phase configurations (a second pair extends to Wye / Delta three-phase).

Air-core 50 µH inductors, 270 V_AC / 380 V_DC, 50 Ω N-type RF port — CISPR 16-1-2 V-network performance maintained at 100 A continuous; insertion loss below 0.5 dB and isolation above 40 dB across 150 kHz to 30 MHz.

Industrial machinery and motor drives drawing up to 100 A — large variable frequency drives, industrial automation cabinets, machine tools, and CNC equipment requiring CISPR 11 / IEC 61000-6-4 industrial emissions qualification.

Three-phase commercial equipment via two LI-1100C pairs — data center UPS systems up to 25 kW, large commercial HVAC and refrigeration plants, three-phase server racks, and other commercial three-phase equipment qualifying for CE and FCC.

EV charging stations and high-power power conversion — AC charging infrastructure on single-phase 240 V circuits up to 100 A, large industrial battery chargers, and grid-tied inverters where the 100 A headroom is required.

Welding equipment and high-current industrial heating — arc welders, induction heaters, and resistive heating equipment drawing tens of amps continuous on single-phase mains with FCC Part 18 or CISPR 11 conducted emissions requirements.

NIST-traceable individual calibration with three-year warranty — impedance, phase, isolation, and insertion loss data supplied per network with calibration certificate; ISO 17025 accredited calibration available on request; recommended LIT-153A or LIT-930A transient limiter accessory available separately for EMI receiver input protection during high-current testing.
