Shinyei - Model FNS-AX4-A20/B63 - Fast Transient Burst Simulators
Electrical fast transients (EFT), such as switching transients originating from inductive load interruption, relay contact bounce, etc., are one of the main causes of equipment malfunctions. Because they can occur anywhere interfering with circuits primarily via mains and interconnection cables.EFT is characterized by fast rise times and a short duration of pulses. Also significant is the fact that EFT comes in bursts with repetition rates exceeding 100kHz.
- IEC 61000-4-4 Ed.3 standard compliance.
- Pre-check function is installed. Inspection before testing is now easy.
- Normal mode test support. Taking account of field troubles is possible. (option)
- Utilize an outlet box that simplifies EUT connection. (option)
- Compared with conventional products, the size has become compact. (Approximately 67% by volume)
- Easy to understand Panel display reduces mistakes in connecting power cables.
- Software control with Windows. (option)
- Next calibration date can be notified. (Windows software only)
- Employ LCD screen with multi-language support and enhanced operability.
- Maximum output voltage of 5 kV and maximum pulse frequency of 2 MHz allow you to test above the standard test level.
- CDN capacity is increased to single phase type AC 240 V 20 A, single and three phase type to AC 600 V 63 A, supporting wider range of EUT.
- Large capacity CDN (100 A or 150 A) option available for Injection test on various EUT.
- Using coupling clamps, EMS probe kits, you can test the signal lines and evaluate the noise immunity on the PCB. (option)
In the real world, an EFT event is a series of pulses with changing amplitudes and repetition rates. For test purposes, the IEC 61000-4-4 standard defines an idealized EFT/B. For anyone who wants to build quality products with an extensive test program from design, qualification, production to diagnostic purpose, the FNS-AX4 simulators will serve as a critical tool with a new level of performance and efficiency meeting and far exceeding the IEC standard requirements
