TESEQ SCHAFFNER NSG432-100 STATIC SMOOTH DRUM ROLLER

Technical Description

The TESEQ Schaffner NSG432-100 is a lightweight, hand-held static discharge system designed for electrostatic discharge (ESD) testing with a discharge voltage range from 2 kV to 25 kV. It supports both single pulse and repetitive pulse operation at 20 Hz, selectable via a toggle switch, enabling versatile testing configurations. The device operates with positive or negative polarity depending on the discharge network employed. Voltage adjustment is achieved through a multi-turn potentiometer, with the set discharge voltage clearly visible on an integrated LCD display for precise control. The system incorporates a discharge capacitor of 150 pF ±10% and a discharge resistor of 330 ohms ±10%, conforming to IEC 61000-4-2 ESD test standards. It delivers fast voltage rise times (<1 ns for air discharge at 8 kV) and peak currents up to 30 A at 8 kV, ensuring accurate simulation of real-world ESD events. The compact, robust design allows for easy handling and the inclusion of various discharge networks and adapters enables compliance with multiple international testing standards such as IEC, ANSI-IEEE, MIL, and ISO. Additional features include a pulse trigger built into the hand grip and optional mounting accessories for repetitive testing setups. The NSG432-100 is suitable for testing equipment immunity to ESD in industrial and military applications where reliable, repeatable discharge simulation is critical.
