Product Description

These low powered devices may be used with 12V 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.

An affordable virtually indestructible source of high voltage for the hobbyist and professional. Now be able to experiment with continuous high voltage spark discharges, negative or positive ion generation, high speed ion propulsion motors, capacitor charging, animal and pest control, shocking applications, night vision power supplies, powering Crookes tubes, Geiger tubes, material testing, corona and Saint Elmo's fire, static generation, flocking devices, ion ray guns, etc.

Produces 25kV open circuit with a short circuit current of less than 1ma, providing a reasonably save high voltage source. Load line is set favorable to ion emitting devices. Circuit has built in open and full short circuit protection and can operate at full output indefinitely. Operation is from any 12 volt 2 amp DC regulated wall adapter, battery or converter (a 12VDC regulated adapter is included which runs off standard 115VAC wall power, and automatically converts to 230VAC for overseas customers). Dimensions are 6" L x 7" H x 2" W.

HV250 Instructions

This device is best-suited for use with our ceramic capacitors or similar (taking care to not overcharge the smaller capacitors). For charging our photo flash and electrolytic capacitors (or similar), the CHARGE800V is better suited.

An external voltmeter is required to monitor charge. Small value capacitors must be charged by quickly applying power, as voltage value can be easily exceeded.

Device is basically a two part system consisting of a high voltage high frequency power supply connected into our five stage open multiplier allowing tap downs in 5 kV increments. Normally such a product would cost many times more than our asking price.

Please contact us for volume purchases.

This item is assembled and ready to use with negative (-) 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.

  1. HV250 best performance for price 5 Star Review

    Posted by on 17th May 2020

    Using the HV250 for an ion-source experiment, I found its performance just as advertised. It is quite rugged and compact, and has so far been essential in my experiments and comparable in performance to other products costing several times as much. For experimenters who do not need the fancy monitoring and enclosures of more expensive products, this device is the best choice and value for the money
