The ONYX 30 from PFIFFNER Systems is an Electrostatic Discharge (ESD) Simulator with a discharge voltage rating from 1 to 30 kV. It has a smart key button with integrated functions that can be defined by the user including polarity switching, LED light, counter reset, voltage stepping up/down and others. This ESD simulator includes a bleeder resistor which is connected in parallel with the output of the high-voltage power supply circuit to ensure high voltage power supply is completely discharged after each injected pulse to an EUT or if the ESD simulator itself will be turned-off by the user (bleed-off). It has a voltage resolution of 100 V steps.

The ONYX 30 has an ergonomic design without any additional base control unit and can be battery or mains operated. The easy-to-use touch screen, ergonomic design, modular RC units, multilingual interface, remote control software, built-in LED light and temperature & humidity display allows for trouble-free use of the ONYX in all types of test sites. It allows a computer to be connected and used to control, collect measurement and reports in seconds. The simulator also features a unique self-test which verifies all of the main components of the unit are working correctly. This ensures that accurate and reliable tests are performed every time the gun is used. The ESD simulator is available in an enclosure that measures 290 x 270 x 110 mm and comes with 2 rechargeable battery packs.
