The Schaffner NSG437 ESD Gun generates pulses from 200 V to 30 kV, both in air- and contact-discharge operation. The simulator is simple, convenient and safe to use. The whole range of parameter setting possibilities, including polarity selection, counter functions and breakdown detection, remains fully available up to the maximum discharge voltage. The NSG437 features a broad range of plug-in network-modules with resistance values from zero ohms and capacitances up to the nF-range. These networks can be simply pushed into place in seconds enabling the NSG437 to meet applications that require multiple R/C network combinations, such as the automotive industry. Schaffner also offers a number of specialized rigid and flexible discharge tips for diverse applications.
