Product Description

• Adjustable Up to 5,000 Volts
• Includes Current-Reducing Lead for Safe "Shockless" Operation
• Can also serve as a Low Capacitance Charger and Voltage Integrity Tester

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.


  • Adjustable output up to 5kV at 4 milliamp.
  • 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 5A adapter (runs on 110-240VAC wall power for both US and international use).
  • Small and light weight, approximately 10"L x 7.5"W x 3.1"H. Made of an ABS Heavy Duty Plastic.
  • 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.

HV350REG/SAFE Further Information


This item is assembled and ready to use with a positive (+) output.
It is also available as a kit with plans and all parts, requiring assembly.
Or as plans (paper or downloadable versions), with parts and assembly required.


Optional 12V Battery:

BAT12/7 - Rechargeable 12V, 7AH battery for field use, 6 x 2.5 x 3.7"

Note: NEVER power 12V electronics from 12V battery chargers, as the chargers can operate up to 20V and may ruin your circuitry. Battery chargers should only be used to charge batteries, never as power supplies.
