NoiseKen FNS-AX4-A20 Fast Transient Burst Simulator IEC 61000-4-4 Ed.3
The FNS-AX4 Series represents Noise Laboratory’s latest generation of Fast Transient/Burst (EFT/B) simulators, designed for IEC 61000-4-4 Ed 3 compliance testing — the 3.0 edition of the standard.
These instruments feature built-in Coupling/Decoupling Networks (CDN) and support both common mode and optional normal mode tests (per ANSI C37.90.1) to ensure comprehensive immunity evaluation for AC and DC power lines.
Their touchscreen operation, multi-language interface, and PC/Android remote-control software make them intuitive, efficient, and ready for modern EMC laboratories.
Key Features
- Fully compliant with IEC 61000-4-4 Edition 3.0 — designed for full calibration of the latest 3.0 standard.
- Built-in CDN (Coupling/Decoupling Network) — selectable coupling phases for all power configurations.
- User-friendly LCD touchscreen with intuitive menus and numeric keypad for simple operation.
- Pre-check function — built-in waveform monitor eliminates need for external attenuator or oscilloscope during setup.
- Three test modes: Standard (preset per IEC), Manual (custom setup and sweep), and Sequence (automated multi-step execution).
- Remote control and data logging available via Windows and Android™ software options.
- Automatic test logging with calibration date reminders.
- Multi-language interface — English, Japanese, Chinese, and Korean supported.
- Optional Normal Mode Test (ANSI C37.90.1) with dedicated coupling balun (Model 15-00013A).
- Comprehensive safety system including emergency stop, 3-channel EUT FAIL input, and indicator outputs.
