Brief Overview on HVDC Power Supplies & Functions

Below you will find our High Voltage DC Power Supplies

These Are Not Static Machines, but Powerful Sources of Usable Current of up to 100ma

(These power supplies are normally used with positive output, but negative output is also available if required.)  

Intended for laboratories and research, as used by physicists, experimenters, and industry for special projects. These devices have a range of current output from microamps to milliamps, voltages from 5 to 500kV, and most are voltage regulated and current regulated. Most of the devices on this page can be purchased as-is. However, if options are required they can be discussed by contacting us either by email or a phone call. Products that are considered potentially hazardous are so noted in their description. Some of the lower powered items can run from batteries or wall power, but the higher power units require wall power.

HV350REG: Low Cost Universal High Voltage Adjustable Regulated Power Supply

Reduced output current is achieved by using the included shock-reducing lead which limits average current to 200uA, allowing for high voltage output with a minimal shock hazard. This mode is useful for reducing often annoying shocks when working in cold plasma (where many interesting experiments produce visual and seemingly amazing displays), ion generation, corona, static electric fields, and other low-current experiments. May be used by younger students to perform many classroom functions with adult supervision.  Demonstrates Ion motors and propulsion, charge projection, wireless object electrification, generate harmless shocks at a distance, force fields, EMP effects on sensitive electronic devices, wireless energy transmission, electro-metal spinning and many other experiments, applications etc.  NOTE: This low current mode also provides a convenient way of testing capacitors and multiplier circuits to verify performance before potting is done, preventing costly rework.

CH10: Low Cost Virtually Indestructible HV Multipliers and Drivers
Voltages from 10 to 40kV from a 9-14V DC input • For the Hobbyist, Student and Experimenter. Many high voltage projects can be built around these “ready to use” working modules.
High Voltage DC Power Supply

Easily battery powered for many uses, from handheld defense devices, to science project lightning displays, to Plasma and Ion sources!

These low powered devices may be used for battery or solar applications. They are short circuit proof and suitable for capacitor charging without a current limiting resistor. They may also be used as low power high voltage power supplies. Units produce power and can give a nasty shock. These are not static electric machines!

DC powered (by battery or wall adapter) high voltage module is capable of charging capacitors and other field worthy applications. Can operate from a 9-14VDC battery pack or wall adapter (not included) and can fit into a small plastic tube of approximately 1.5" ID. This module is available at several maximum output levels that can supply from 10kV up to 40kV output (tap points along the HV multiplier stack for lower voltage outputs in 5kV to 10kV steps, or vary the input from 9-14VDC for adjustable output voltage, but do not exceed 14VDC input or the HV power supply can be overdriven and damaged).

Note: these multipliers are powered by our NEONXUL (MINIMAX30) driver. For higher output (roughly 50% greater final voltage), use our MINIMAX70 driver.

Standard output is normally positive (+), but negative (-) output is also available -- please choose when ordering, as the units cannot be switched between positive and negative output due to the diode orientation on the multiplier stack. Kit versions may be built - or + depending on how you wire the diodes.

Neon Display Transformers

Include a very simple electric field, static charges and high frequency potentials often found around gas discharge lighting, high potential radiating alternating current fields often found near high tension power lines and other sources such as radio transmitters.

High voltage measuring probes are used for actual contact measuring dc potentials up to 200kv. 

ENPROBE10 - Energy Probe Radiant Energy Indicator and E field detector

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 moderately weak 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.

IOD40 - ALL NEW Ion, Charge and Electric Field Detector
Detects both positive and negative electric fields produced by ions, ultra low static fields, lightning, paranormal entities and other associated phenomona by using a special DC amplifier and low leakage switch. Very useful device in warning of approaching dangerous storms.

Highly Sensitive, Detects Ultralow Background Disturbances

ALL NEW IOD40 detects both positive and negative electric fields produced by ions, ultra low static fields, lightning, paranormal entities and other associated phenomona by using a special low leakage switch.

This very versatile tool detects both positive and negative electric fields produced by ions, and ultra low static fields This unit is sensitive enough to detect the minute charge produced by just rubbing a piece of plastic and bringing the probe in proximity. It easily measures the electric field during a thunder storm or other high static conditions long before the storm arrives.

Extremely useful for mapping the electric fields associated with high voltage generators. Indicates dangerous "E" fields that may damage sensitive electronic circuits or components. Detects those that can be dangerous to personnel. Detects the presence of weak to strong static charges from lightning, potential corona points and output of ion generators, leaking high voltage insulators and wiring insulation. A very valuable device for the high voltage researcher and experimenter.

Unit is built into a handheld 6" x 3" x 1.5" metal box with extendable detection antenna probe. Simple high performance circuitry is powered by a single 9 volt battery that seldom needs replacement.

Detector indicates field strength using an analog meter with a sensitivity control. Includes a potential dangerous high charge field condition by an indicating LED. Switch selects positive or negative charge fields. A response switch allows fast or slow response. A simple external terminal provides a connection point for a grounding lead. Front-mounted RCA phono jack provides a facsimile out for remote monitoring or trigger circuitry for alarms, x/y recorder, etc.

It has been observed that certain paranormal activity is often accompanied by a distortion of the electric field. These changing fields are usually too weak to be detected by conventional detectors. The IOD40 has on several occasions detected unexplained fields in coincidence with other events. At the time of this writing a study is being done at several selected grave sites to see if the distortion in these weak fields can be detected and correlated with other unexplained events.
