63A High-Current Three-Phase LISN
- Implements a precision-controlled 50 Ω / 50 µH four-conductor impedance stabilization network fully compliant with CISPR 16-1-2 and ANSI C63.4.
- Maintains controlled impedance characteristics from 150 kHz–30 MHz with verified isolation exceeding 40 dB and insertion loss below 11 dB.
- Supports 63 A continuous per line allowing full-load conducted emissions validation of three-phase EUTs.
- Utilizes air-core inductors to eliminate magnetic saturation and maintain phase accuracy under high current conditions.
- Improves measurement repeatability in compliance labs by providing defined and stable power line impedance independent of the facility mains.
- Enhances test setup accuracy for motor drives, EV chargers, UPS systems, converters, and industrial automation equipment.
- Reduces measurement uncertainty by isolating the EUT from upstream power disturbances and external noise sources.
- Optimizes multi-phase testing efficiency through remote fiber-optic line switching, minimizing reconnections and operator handling.
- Protects EMI receivers and spectrum analyzers via integrated transient limiting and broadband filtering.
- Supports structured EMC workflows with forced-air cooling for extended high-current testing sessions.
