Power Supplies - High Voltage, High Frequency by subcategory:
Plasma Generators
HV Drivers
Gas Discharge Power Supplies
Energy Probe

 

Please read to fully understand the capabilities & advantages of our plasma power sources!

The PVM-series Multifunctional Power Sources have the ability to tune out the indirect reactive capacitive coupling often required in powering Dielectric Barrier Discharge devices (DBD's), Plasma Cells/Containers, Transducers and other similar devices. In this type of operation, when the coupling capacitance is “tuned out,” an efficient operation is attained. If this capacitance is not tuned out, then an inefficient much higher voltage will be required to produce useful plasma (this is mathematically explained in the Tech Data download). 

These PVM-series power supplies can also be set to power conventional resistive loads (where tuning to resonance isn't needed), while also providing a wide range of frequencies to your target load. An example would be a gas-filled vessel with internal electrodes. The voltage is fully adjustable up to 20,000 volts rms with full-range duty-cycle controlled current. All these features make the PVM units suitable for many applications.

As an example, the PVM2000 can be used to make a spectacular Jacobs Ladder or a large DRSST Tesla Coil, power Huge Neon Gas Displays, create Talking and Singing Plasma Gas -- all of these with minimal modification to the stock device. It can also be an excellent power driver for a high powered Cockroft Walton Voltage Multiplier producing a powerful 2kW bolt of lightning, plus many other functions. The PVM500 will produce the same results, but of course to a lesser effect.


PVM500 Plasma Resonant and Dielectric Barrier Corona Driver

Circuitry for tuning out capacitive coupled loads allows a real power transfer up to 300 watts. May also be used as a conventional high voltage tunable high frequency power source for many other applications.

PVM500 Instructions
PVM500 Schematic
Duty Cycle Writeup

This reliable and flexible medium power Plasma Driver tunes out capacitance to efficiently drive light capacitive loads, allowing high real power operation of gas displays, chemical, ion, plasma, ozone cells, vessels, transducers and other research functions. To achieve an equivalent effect without a unit having these capacitance-tuning properties would require an extremely high output voltage. Instead, this is accomplished by simple resonance and observation of when the meter rises to indicate the point of capacitance cancellation in complex loads. You will find this device highly valuable in this type of research. Output power may be adjusted from 10 to 300 watts, and it runs on standard 115V AC wall power (or 220 volts with optional step down transformer).

Unit is intended for the experimenter/researcher working in plasma research physics or other similar fields. A certain amount of knowledge helps to effectively operate the unit as in some cases it must be tuned to the output capacitance and resistance of the load. This is basic boilerplate technology to any electronics engineer and simply involves the handling of complex numbers, polar notation or simple impedance matching algebraic formulas.

Other applications of this device include use as a high powered driver for single ended and proximity gas display tubes, plasma globes and other vessels. Checking for potential damaging resonances in large gas displays, or to 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, HHO gas production, and many other research functions.

Will tune out capacitive loads of 25 to 200 pfd (these can be ozone, chemical, and plasma cells, gas ionizing and igniting, etc.).

PVM12 Instructions

INPUT - 12VDC 3A 
OUTPUT - Variable 1k-20kV (auto-adjust)
FREQUENCY - Variable 20k-50kHz (direct adjust)
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
thermag

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.
