Teseq NSG 435 ESD Simulator/Gun; 16.5kV Air, 9kV Contact

Ergonomic design and advanced functionality. The pistol-shaped NSG 435 simulator is designed to sit comfortably in the operator’s hand, with current operating conditions constantly displayed and clearly visible.

NSG 435’s microprocessor-based controller and multifunction keypad provide the operator with instant access to its comprehensive range of built-in functions. The LCD panel continuously displays the operating status and all user-selected test parameters.

NSG 435 has its own internal, battery operated high voltage generator. In addition to the pre-programmed, standard IEC pulses, the user can create custom tests using single or repetitive discharges with selectable rates and manual or automatic polarity switching. An optional mains supply is available for extended test operation or for use when the battery is being charged.

A range of interchangeable discharge networks is available, including EN, ANSI-IEEE, and ISO. The unit comes with a standard 150 pF/330 Ω discharge network for tests to IEC/EN 61000-4-2.
