Plasma Generators

Energy Probe


It should be noted that the voltage these units generate is not a function of the turns ratio on the transformer. These transformers have been set to produce a voltage of 10,000 V peak by the turns ratio. The transformer secondary circuit mathematically is equated as a voltage source driving a reactance. This reactance is controlled by the airgap in the secondary only of the transformer, the number of turns, and the frequency that is tuned to. This is the inductance part of the resonant system that tunes out the capacitive reactance of the load.  When connected to a capacitive load the frequency should be tuned to obtain a resonant rise in voltage that is going to be dependent on the Q of the circuit being driven. So now the voltage output is a function of these parameters. The transformer has built-in protection circuitry that will shut the system down should the voltage on the transformer exceed the rating that the transformer is insulated for. Usually for at least 25,000 V peak.

PVM500 Plasma Resonant and Dielectric Barrier Corona Driver
Medium Powered Plasma Driver is capable of delivering up to 300 watts of real plasma power when properly tuned.

PVM500 Schematic
Duty Cycle Writeup

Product is designed to tune out the capacitance of containers, cells, plates, and other containments necessary for the production of a plasma, corona, gas ionization etc. Without a unit having these capacitance-tuning properties, it would take extremely high output voltage to achieve an equivalent effect. This is accomplished by simple resonance and observing the meter for a rise indicating the point of capacitance cancellation found in complex loads. You will find this very valuable in this type of research.

High powered driver for single ended and proximity gas display tubes, PLASMA GLOBES and vessels. May be used to check for potential damaging resonances in large gas displays. Indicate the power required for a particular display.

May be used for sputtering, plasma etching, chemical vapor deposition (CVD) coating, and physical vapor deposition (PVD) coating, electro-chemical reactions, and many other research functions.

Intended for capacitive loads of 5 to 200 pfd (these can be ozone, chemical, and plasma cells, gas ionizing and igniting, etc.).

PVM12 Instructions

OUTPUT - Variable 1k-20kV
FREQUENCY - Variable 20k-50kHz
CURRENT - Reactance Limited to 20mA

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.

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 reccommended 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.

Energy Probe

Radiant Energy Probe and E-Field Detector

Probe detects E fields produced by electrical activity and other unknown anomalies. Unit uses no batteries or other sources of power. Unit can also provide a three dimensional output "footprint" of medical healing machines such as LAKHOVSKY coils, High voltage generators, Ion machines, Dangerous lightning levels, Power line E field gradients, High frequency radiation from TESLA coils and similar devices. This probe is used by paranormal researchers as seen on some TV shows.

This device is for detecting strong E fields, like those from plasma globes, tesla coils, ion generators, etc. It is not intended for weak E fields, like those generated by many household items. If you need something to detect household or weaker energy fields, we suggest our IOD40.

The apparatus is electrically balanced and designed in the shape of a wand with a 2 inch brass sphere at its detecting end. The handle is 1” OD x 9” of treated polycarbonate with plated metallic tape wrapped around the ends. A red neon indicator lamp (a standard bulb that should last for years, but can easily be replaced if needed) flashes upon detection and increases as you get closer to the source, or if the source gets stronger.

Probe detects:

  • Potential free energy field locations
  • Electric fields produced by ions sources
  • Dangerous static charges
  • Paranormal and UFO energy fields
  • High frequency radiation
  • Weather phenomena lightning
  • High voltage leakage points
  • Plotting a three dimensional footprint of E-fields of HV sources
  • Detects strange and otherwise unidentifiable sources

This handy unit is easy to use and can check the validity of output energy of various healing machines and other radiating products. It is a must-have product for those working in these energy fields.
