Product Description

HV Power Supply, 20kV pk-pk, 20-30mA at 20-60kHz. Designed for Large Single Neon and Gas Artistic Displays up to Four Feet in Diameter Sphere Where the Virtual Ground Return is the Intrinsic Capacitance of the Surroundings.

Powers up to 48" Plasma Globes
Single Electrode Operation

High-powered front panel adjustable output plasma driver is intended for larger plasma globes up to 48 inches diameter (about 33 cubic feet), or similar-volume plasma columns and large gas filled discharge vessels. (Above this volume, our PVM500 should be used.) Rectangular shaped unit is 10.25" x 2.75" x 4" (LxWxH) and is built on an aluminum chassis with plastic cover. The front panel holds the fuse, power control adjustment, indicator lamp, and power input cord. The output end is open with a 12" 30kV high voltage wire and 4' grounding lead. Factory set open circuit voltage shutdown protects the transformer from too-light and no-load operation. Internal circuitry protects against short circuits. Open circuit voltage is 20kV pk-pk with a short circuit current of 25 ma load lines at 125 watts of output. The power adjust control varies the frequency from 20 to 60 kHz and controls output. Full load output line current is 1.5 amps.

PVM400 Instructions

There are 3 versions of the PVM400 available:

PVM400: The standard version runs from a US wall outlet (115VAC).

PVM400DELUX: The "Deluxe" version also runs from 115VAC US wall power, and has the added feature of allowing manual control over the display texture (the on/off cycle), and includes a 3.5mm audio jack to sync with an audio input (or other device; see further information below) so that if this Deluxe power supply is lighting up a plasma display, the plasma will be seen to respond to the music. (There is not a 220VAC version of the Deluxe power supply, so a stepdown transformer, such as our TR220/110/300, will be needed to run the Deluxe power supply from 220VAC for international use.)

PVM400-220: The "220VAC" version is a PVM400 that runs at 220V wall power for international use.


INPUT: 115 VAC, 1-2 amps (plugs directly into wall outlet)
OUTPUT: Variable 1-20kv
FREQUENCY: Variable 20-60khz (varies with power adjust)
CURRENT: Reactance Limited to 25 ma
SAFETY: Over Voltage Shutdown Manual Reset
OPTIONS: Flashing, Sound & Music Control, and Pulsed Duty Cycle Attachments Available on PVM400DELUX


Notes on the DELUXE Model

1. The model PVM400DELUX has a built-in controller that allows the display texture to be changed over a considerable range. This feature greatly enhances the display effect by controlling the ratio of pulse on to off times.

2. Contains a 3.5 mm audio jack that accepts a 5 volt level allowing the unit to flash to any external source. Excellent effect when activated in coincidence to the base beat of any music system when using our BASEBEAT10 as shown below. Unit can be made to flash at a 50/50 rate from 1 to 30 flashes per second with the below FLASH10.



We have 3 different modules that can control the neon transformer output. The BaseBeat module dynamically responds to music, with adjustable patterns, sensitivity, and duration of output. The Flasher module has the traditional on/off cycle, adjustable from 10 cycles per second to one cycle per 5 seconds, and able to control 1 or 2 transformers.
BASEBEAT Instructions

BaseBeat Musical Module

Musical light flasher responds to the beat of the music. Great visual aid to any band or home music sound system. Neat effect when using our DC75 under-car neon transformer.
ATTENTION Music Lovers!
  • Makes neon lights flash to the musical base beats
  • Neat action display
  • Great addon to existing music systems

Interfaces with our PVM400DELUX transformer (or any transformer with an audio/animation control input) and can control a large display of neon tubing to flash along with the base beat of the music.

Great for bars, clubs, concerts, bedrooms, living rooms -- anywhere music is played and you would like a neat visual effect. Ready to use and easy to operate, just connect to any audio output and adjust for effect.

BASEBEAT10 - Ready to Use

Flasher Module

Great attention getting and special effects. Flash two displays in anti-coincidence. Use with our DC75 auto neon and any transformer with a control lead. Neat effect for under-car neon.

Flashes a single PVM400DELUX, or two in anti-coincidence -- that is, one "off" the other "on" and reversing. Mating plugs fit into the PVM400DELUX unit. Adjustable flash rate.

Shown as board-level, and operates from included 12 volt wall adapter. Sold in a plastic channel with adapter wired in and two mating plugs for our PVM400DELUX.

  1. Works great. 5 Star Review

    Single-ended output provides AC high voltage, suited for many applications. Variable power control a useful feature. Very quiet even at higher power levels.
