Marx Generator 2.0 Kit - 100kV High Voltage Generator

Marx Generator 2.0 100kV Kit




Welcome to the Marx Generator 2.0. This amazing kit is the only amateur based Marx Generator kit on the market. The Marx Generator 2.0 kit will generate a 100kV high voltage pulse of electricity - much of that like lightning - in the confines of your own home. As you may recall, a Marx Generator is a multi-staged voltage multiplication device in which each stage capacitor's are charged in parallel, and then with the aid of carefully spaced spark gaps, discharged in series creating a very intense, ultrafast rise-time high voltage output pulse. This is the type of technology that is used to simulate real lightning and Marx Generators the size of ten story buildings have been designed and used to test lightning on aircrfat, instruments, and other industrial products. Now you can build your own Marx Generator in the comfort of your school or home.

The Marx Generator 2.0 is a 15-stage device and has a 6kV capacitor for each stage. Unlike the smaller Marx Generator 1.0 kit we presently offer, the Marx Generator 2.0 offers stage capacitances 10 times greater. With a 6kV charging voltage, the theoretical maximum high voltage output pulse would be 90kV or nearly 100kV! It can produce output arcs of approximately 4" depending on the input voltage, spark gap spacing, and tuning, and atmospheric conditions. The kit comes with all capacitors, charge resistors, series limiting resistors, as well as right angle mounting brackets so that it may be mounted vertically. The total height of these Marx Generators is a whopping 18" high and is made from extremely strudy 0.124" thick FR-4 and also features internal cut-outs so that each spark gap can be seen during operation.

The spark gaps used in these devices are made from brass alloy which provide a very stable and consistent arcing voltage. The spark gap distances can be easily modifed according to the end users specific requirements.

The input to the Marx Generator must be a high voltage source of at least 1kV and not more than 6kV. If you do not have a charge source available, we recommend purchasing our HVPS3 6kV, 10W power supply. There is an ordering link below.
