NOISEKEN Electrostatic Discharge Simulator ESS-B3011A/GT-30RA/GT-30R3302KA

EN/IEC 61000-4-2 Ed2 & ISO 10605 Ed2 Compliant Cost-oriented Basic ESD simulator

“NoiseKen” ESD simulators can reproduce and simulate the ESD from a charged human body intentionally for testing whether electronic equipments become malfunctioned or work correctly with the ESD influence, and the simulators conform to IEC61000-4-2 Standard which is standardized by International Electrotechnical Committee (IEC).

Electrostatic Discharge Simulator


ESS-B3011A & GT-30RA / GT-30R3302KA




  • EN/IEC 61000-4-2 Ed2 Compliant (B3011A)
  • ISO 10605 Ed2 Compliant (B3011A) (Note: Optional gun head and CR units are required.)
  • “Discharge detecting function” to realize the air-discharge confirmation (B3011A)
  • “Lightest Discharge Gun in the market “to lighten the continuous operation (GT-30RA)
  • “White LED Irradiator” to facilitate the visualization of the discharging point (GT-30RA)
