Data Sheets User Manual Teseq - ESD Brochure


The Teseq (Schaffner) NSG 435 is a comprehensive ESD Gun/Simulation System for air discharge to 16.5kV and contact mode to 9kV. Transient Specialists is the only authorized sale partner/distributor of Teseq ESD simulators in the United States. It comes with an 150pF/330Ω discharge network for IEC 61000-4-2 testing and tips for both air and contact discharge. All of our rental equipment comes with an accredited A2LA ISO 17025 calibration standard, with no additional costs.

Take advantage of a two year manufacturer's warranty on parts and labor when purchasing an NSG 435 test system. We also offer a variety of accessories, tips, and additional networks allowing for enhanced testing capabilities. Often times the simulators and accessories are in stock, allowing for immediate or near immediate delivery to your testing location.

The pistol-shaped NSG 435 ESD Gun is designed to sit comfortably in the operator’s hand, with current operating conditions constantly displayed and clearly visible. It also allows for use in environments without easily accessible power supplies where other test equipment require additional consideration. The user-selected test parameters are shown on the LCD panel and easily adjusted with the keypad.

This ESD simulators microprocessor-based controller and multi function keypad provide the operator with instant access to its comprehensive range of built-in functions. The product comes with many standards test settings pre-programmed to allow for tests to be run efficiently. The voltage of this Teseq product can also be programmed from 200 V to 16.5 kV depending on your immunity testing requirements.

Teseq, a leading manufacturer of EMC test equipment offers this base line simulator as part of a the NSG series of simulators. It provides all the necessary requirements for many common standards and field testing requirements. The series of simulators includes 30kV capable simulators, including the NSG 437 and NSG 438.
