Ten small rectangular modules with red and green input wires and matching output leads, loose on a plain surface

GCON

GCON High Voltage Arc Generator 10pcs DC 3.6V to 20kV

SKU CH-A2KK-JDJ82

Pack of ten DC 3.6V to 20kV high-voltage arc modules for ignition and experiments

  • Generates 20kV high-voltage arc from low-voltage input
  • Operates on single 3.7V lithium or dual 18650 cells
  • 100 mm colour-coded leads simplify safe wiring
  • Delivers continuous high-frequency arc for up to 20 seconds
  • Suits student electrical experiments and ignition projects

Arc generator kit purpose

This pack contains ten high-voltage arc generators designed for laboratory demonstrations and ignition experiments. Each module steps a low DC input up to a 20000 V pulse output. The units are intended for students and hobbyists conducting supervised electrical studies. They are not suited for continuous-duty power supply applications.

Sustained operation behaviour

The supplier rates continuous run time at 20 seconds before a cooling pause is required. During that window the arc maintains a high-frequency pulse pattern at the stated output level. Extended operation beyond the rated interval is not supported by the documented specifications. Thermal management is the responsibility of the user.

Critical selection specification

The input voltage range is DC 3.6 V to 6 V with a 1.5 A current draw. A single 3.7 V lithium cell or two cells in series such as 18650 types rated above 2000 mAh are the documented power sources. Supplying voltage outside this window will prevent correct function or damage the module.

Questions about this item

How hot does the 20 kV arc get when the module runs for the rated 20 seconds continuously?

The generator produces a high-temperature, high-frequency arc that can instantly ignite cigarette paper and other combustibles during its 20-second continuous run.

Which power source must I already have to run the module at its 3.6 V to 6 V input range?

A single 3.7 V lithium cell such as an 18650, or two cells in series, with the protection board removed and a capacity above 2000 mAh.

Will the red and green 100 mm leads connect directly to the screw terminals on my older lab supply?

The module uses 100 mm flying leads — red for positive, green for negative — so you will need to terminate or adapt them to match screw-terminal inputs.
