Introducing the NoiseKen ESS-PS1 Electrostatic Discharge Simulator with GT-31S ESD Gun!

Posted on: November 12th, 2025 by Kane Brady

Electrostatic Discharge (ESD) remains one of the greatest threats to product reliability. Are you certain your devices can survive real-world events and regulatory scrutiny?

Introducing the NoiseKen ESS-PS1 system with the GT-31S ESD Gun—the ultimate, compliant solution for your immunity testing lab. This powerhouse system delivers repeatable, high-precision discharges up to 30.5 kV, ensuring compliance with both IEC 61000-4-2 Ed. 3.0 and ISO 10605 Ed 3.0 standards. With features like its intuitive LCD touch panel, battery-powered portability for on-site testing, and flexible test modes, the ESS-PS1 isn’t just a simulator—it’s your definitive tool for EMC confidence. Read on to see how this system streamlines compliance and fortifies your next product launch.

  • Complies with IEC 61000-4-2 / ISO 10605 standards.
  • The discharge gun is equipped with a touch panel for improved operability.
  • Battery operation improves portability and makes testing of large equipment more convenient.
  • Equipped with a pre-check function (pre-start inspection) to ensure testing is carried out properly.
  • Uses a discharge module in which the discharge cup and CR unit are integrated.
  • Equipped with an automatic discharge module recognition function helping to reduce mis-attachment.
  • Equipped with a discharge detection function that notifies the user of discharge detection.
    • Air discharge mode only.
  • Remote control from a PC via optical communication is also possible.
    • Please consult with us.

NoiseKen ESS-PS1 Electrostatic Discharge Simulator with GT-31S ESD Gun

Electrostatic discharges caused by a charged human body approaching an electronic device’s operation panel, button switches, or enclosure generate high-voltage, high-frequency noise that can cause electronic devices to malfunction. An electrostatic discharge simulator is used to simulate such electrostatic discharge phenomena and evaluate the resistance of electronic equipment to electrostatic discharge.

Touch Panel on the Discharge Gun: Easy-to-understand, intuitive design. The display language can be switched between English and Japanese, and in “Standard Mode,” test conditions for IEC and ISO standards can be easily set.

The Main Unit is Battery Powered: Superior portability makes it effective for testing mobility equipment, large medical equipment, office equipment, etc.

When performing electrostatic discharge testing, do you ever feel unsure as to whether the test is being carried out correctly? With the three pre-check functions (high voltage power supply output check, insulation failure check, and discharge relay operation check) provided in our simulator, such concerns can be eliminated. Before starting a test, the simulator can easily check for any abnormalities, making the test more reliable and secure.

Equipped with an automatic recognition function to identify the type of discharge module installed in the discharge gun. Automatic recognition of installed discharge modules reduces installation errors and ensures that time isn’t wasted

Conventional discharge guns had a CR unit and a discharge cup attached, but in the GT-31S discharge gun, the CR unit and discharge cup are integrated into 1 unit as a discharge module.
By replacing the discharge module, testing to IEC 61000-4-2 and ISO 10605 standards is possible.

The ISO 10605 test can be conducted using the accessory set (GT-ISOSET-A) for the GT-31S.
