Additional Information about DC Power Supplies

 


These High Voltage DC Power Supplies Are Not Static Machines, but Powerful Sources of Usable Current of up to 100 ma.

Intended for laboratories and research, and 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 this can easily 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 by line power with a wall adapter. The higher powered units require direct line power.

All power supplies are positive unless requested to be negative.

High Voltage DC Power Supply

HV350REG/SAFE Instructions

HV350REG/SAFE Further Information

Highly reliable and versatile power supply for many high voltage laboratory and research applications.

Great for ion sources, object charging, EMP generators, electro kinetic and pulse magnetic systems. Can also be used to charge small energy HV capacitors such as ceramic discs, doorknob capacitors and similar types. Also for HI POT testing or as a testing system to verify standoff voltage ratings (such types of capacitors are often used in multipliers or systems that may be potted, so verifying these capacitors prevents costly repairs should one fail).

A "safe mode" of operation is achieved by using the included shock-reducing lead which limits current to 200uA, allowing for full high voltage output with a minimal shock hazard. This mode is useful for safe studies in cold plasma (where many interesting experiments produce visual and seemingly amazing displays), ions, corona, stable electric fields, and other very low-current applications. The low current reduces possible painful electrical shocks if improper contact is made, which makes the power supply suitable for use in schools and by the younger hobbyist. 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.

This is a voltage-regulated power supply; see the HV350 for our current-regulated version.

FEATURES:
  • Adjustable output up to 20kV at 1 milliamp / 35kV at 700ua.
  • Front panel adjustable voltage control with voltmeter, with a panel lamp to indicate “in or out” of regulation.
  • Output is voltage regulated through the output current range.
  • Special output connector for "Safe Mode" operation. “Normal Operation” at full power uses a normal lead. Both leads are included.
  • Open- and short-circuit protected.
  • Output is end-point grounded for convenience.
  • Unit is powered by an included 3-wire grounded 12VDC 4A adapter (runs on 110-240VAC wall power for both US and international use), and a 2.5mm plug with wire leads is also included should you want to run the power supply from a 12VDC battery.
  • Small and light weight, approximately 8"L x 4.25"W x 4.5"H. Made of an aluminum base with a military gray PVC cover.
  • Highly reliable device can be used for powering ion sources, antigravity lifters, object charging, EMP experimenting, electro kinetic and pulse magnetic systems. Excellent for many laboratory and research applications.
  • This unit has been approved by our testing labs to be around younger students and hobbyists. Nevertheless, qualified adult supervision is suggested.

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. 


Energy Probe Radiant Energy Indicator and E field detector
NOT INTENDED FOR ACTUAL CONTACT TO HIGH VOLTAGE POINT AS MAY CAUSE A LETHAL OR SERIOUS SHOCK
thermag

Radiant Energy Probe and E-Field Detector 

USE CAUTION AROUND HIGH VOLTAGE NEVER CONTACT OR USE CLOSE TO A KNOWN HIGH VOLTAGE POINT

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.

ALL NEW IOD40 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.
iod40

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.
