Product Description

12-Volt Single-Electrode and Proximity Driver Will Power up to a 14” Plasma Globe and Many Other Neon and Artistic Displays. Make a Plasma Tornado.


Front panel adjustable output power supply, excellent for driving plasma globes up to 14" in diameter (about 1440 cubic inches) and other similar-sized displays and cells such as our plasma tornado, neon tubing, etc. Single ended driver for gas-filled displays operates from 12 volt input at 3A minimum. Variable open circuit voltage of 1k-20kV with short circuit current of 20mA. Frequency is adjustable from 20k to 50kHz and is controlled from the front panel; voltage auto-adjusts to capacitive load & frequency. What you will find in practice is that as you are adjusting the frequency, the display will suddenly "come to life" and get very bright -- this is the peak harmonic resonance of the circuit. There may be other harmonics, but there will be one that is strongest, and you can then fine-adjust this power supply to your desired output.

This unit is built on a metal chassis with plastic cover. Size is 2.75 x 3.25 x 7.5" rectangular with a 12" output lead. The included 12V adapter operates from any wall power (100-240VAC), so both American and international customers can plug this into their wall outlets and be ready to go.

INPUT - 12VDC 2A (includes a 12V wall adapter)
OUTPUT - Variable 1k-20kV (auto-adjust)
FREQUENCY - Variable 20k-50kHz (direct adjust)
CURRENT - Reactance Limited to 20mA

    I have filled and seal test tubes with rare gases at atmospheric pressure.

    It ionized the gas with no problem.

  2. Great high frequency supply 5 Star Review

    I'm using this as a High Voltage supply for various experiments and it works very well. If you need a quality high frequency AC you really can't go wrong with this compact unit.

  3. Sturdy and Reliable 5 Star Review

    This driver runs my custom plasma jars and CW multipliers very well. Proven to be an invaluable lab tool. Highly recommended for any type of low power, HV work! Great product!
