Impedance Matching Network Features 

      • Impedance Matching Network - Surge generators IEC 61000-4-5 Ed.3
      • Surge output HV-COM fitting, if no CDN is used
      • Impulse Range: Up to 8,000 V and 4,000 A
      • Match Surgepulse to H-field Antenna circuit as per Draft IEC 61000-4-9 Ed.2
      • Turnkey Solution - Arrives Ready for Testing!


The EM Test IMN2 replaces, at the HV-COM output, the surge generator's external coupler. It is required as per IEC 61000-4-5 Ed.3 so that the pulse specifications can be accurately matched.  It is required for the following applications: -Direct surge application to an EUT without coupling network - Surge impulse matching for pulsed H-field tests to match the waveshape using magnetic field antenna - Surge impulse verification at the HV - COM output when no coupling decoupling network is used

Working for a testing company I deal with renting equipment all the time.  Transient Specialist is the first company I call on my list of rental houses because of their great personnel, prompt delivery of the equipment, knowledgeable and accommodating to the customers needs.
