Teseq NSG 438A ESD Simulator/Gun with built in charge remover

NSG 438A comprehensively fulfills virtually all international standard requirements. Based on over 60 optional discharge networks, the NSG 438A can meet any of today’s automotive manufacturers’ standards.

The simulator is simple, convenient and safe to use. The whole range of parameter settings including polarity selection, freely adjustable pulse repetition, counter functions and discharge detection is available up to the maximum discharge voltage.

The color touch display and keypad for parameter input shows the precise functional and test data with user-selectable language for convenient and safe operation worldwide. The simulator contains variable threshold selection for accurate discharge detection. This detection feature can be switched off when testing EUT’s with non-conductive surfaces, such as plastic housings. Pre-programmed settings for IEC 61000-4-2 and ISO 10605 ensure that the simulator is automatically set up correctly and the appropriate discharge network is installed.

The actual RC value is displayed at all times. Molded HV discharge networks in solid cases eliminate ionization and leakage current effects. Precisely tuned combinations of RC components guarantee wave shape parameters to be within tolerances. A unique activity log is included so that the types and numbers of ESD simulations can be easily scrolled through to check what has been tested and in what timeframe.
