An 8kV ESD generator has been in order since edition 2 of IEC 61000-4-2, as most our customers didn't require a 15kV air discharge test. EMC partner heard the cry. Is it cheaper? Sure, but not as much as you'd think. Redesigning, sourcing, prototyping and doing all the product design and development isn't practical when a few hundred ESD guns are sold a year.
Regardless, it is still a good solution that the market should warm too.
Now, EMC Partners Overview:
The EMC Partner ESDEX8 8 kV ESD Generator is a compact and reliable solution for simulating electrostatic discharge events in laboratory and pre-compliance testing environments. Designed for ease of use and consistent performance, it enables engineers to evaluate the ESD immunity of electronic devices during development and validation.
Operating with a standard 150 pF / 330 Ω RC network, the ESDEX8 delivers controlled discharge pulses in accordance with IEC 61000-4-2, supporting both contact and air discharge methods up to 8 kV. It is suitable for testing a wide range of electronic products, including consumer devices, industrial equipment, and embedded systems.
Its stable output and straightforward operation make it ideal for routine testing, design verification, and troubleshooting across R&D, quality assurance, and pre-compliance lab environments.
In practice, ESD Guns customers use the ESDEX8 for pre-compliance testing, product validation, and troubleshooting of electronic devices during development. Engineers apply controlled ESD events to critical points such as enclosures, connectors, PCBs, and user interfaces to identify potential failure points early and improve product robustness before formal compliance testing.
It is also commonly used to replicate standard ESD conditions based on IEC 61000-4-2, as well as to recreate field-related ESD issues and verify corrective design changes. This makes the ESDEX8 a practical and dependable tool for routine ESD testing in small to mid-scale EMC testing environments.
Applications:
Pre-compliance testing, product validation, and ESD troubleshooting
Simulation of electrostatic discharge on enclosures, connectors, PCBs, and user interfaces
Early-stage design testing to identify vulnerabilities and improve robustness
Replication of standard ESD conditions based on IEC 61000-4-2
Recreation of field-related ESD issues and verification of design fixes
Routine ESD testing in R&D and pre-compliance laboratories
