Product Description

Current Controlled Version
Excellent for charging small Marx Generators, EMP Generators, capacitors and small capacitor energy banks; to power small antigravity lifter science projects and kits; and for many other applications involving these output parameters.

Continuous output current is below 5ma and not dangerous but can produce a painful shock. This is not the case where external capacitance can be charged above 50 Joules and produce both a painful & dangerous discharge!

All new 35 kilovolt at 1.5 milliamp power supply with adjustable current control is both short- and open-circuit protected. Small, lightweight unit is powered by a 12VDC 4A wall adapter (included) that runs off standard 115VAC power (automatically converts to 230VAC for overseas customers), or 12V batteries for field use (not included). Highly reliable device can be used for powering ion sources, object charging, or as an excellent current source for charging capacitors in EMP, electro kinetic and pulse magnetic systems. May also be used for many laboratory and research applications. Available as a kit or ready to use with options as listed.

Front panel control is off/on switch that also adjusts to control the current. fuse and low cost low corona free connector. HV output is end point grounded for convenience. Small and light weight is approximately 8.75"L x 4.75"W x 4.75"H.

Current regulated version must be connected to a load of between several ohms to no more than 50 megohms. Unit is short circuit protected.


This item is assembled and ready to use with a positive (+) output.
Or as plans (paper or downloadable versions)parts and assembly required.


See our HV350REG/SAFE if you need a voltage-regulated version.


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.
