GRA-Series Power Supplies

We've created a set of plans especially for the GRA-series of high-voltage power-supplies from Information Unlimited. If you've purchased a GRA-series high-voltage power-supply from Information Unlimited, please follow the following link to download instructions specific to your model of power-supply. Click here

The GRA-series power-supplies were designed especially for use with Lifter technology, and are both more dependable and far safer than the conventional computer-monitor HV-tap method for producing power. To learn more, use the following links: GRA-Series, HVolt-Series

Safety Information

Safety Documentation: Please download and read a copy of the Safety-Guidelines documentation from American Antigravity, as shown in the left-hand column. Lifter-technology currently involves working with very high voltages, so you should take the safety precautions recommended in the safety-documentation to help you stay safe while testing Lifters. For instance, if you're using the computer-monitor to power your Lifter, unplugging the picture-tube can save you from dangerous capacitive discharges

Computer-Monitor vs.GRA: Computer monitors are much easier to find than a good high-voltage supply, but they often produce unreliable test-results due to manufacturing and design differences between different models. Additionally, the picture-tube on a computer monitor can store a dangerously high potential-voltage, similar to a very-high voltage capacitor. The GRA is a more predictable piece of equipment, and is adequate for most Lifters up to 2 to 3 feet per side, after which we recommend purchasing an H-Volt 50 or the equivalent power-supply (50kV, 5mA, pulsed-DC output).

The GRA supply from Information solves many of the problems of working with a computer monitor, and AAG recommends it as a good, safe alternative if used in the manner recommended by Informaiton Unlimited. You can find more out about these supplies on the Info Unlimited website.

Power Supplies: The American Antigravity website recommends the GRA power-supply only because we have had great success with it and found it to have a reasonable price. There are a variety of high-voltage supplies available on the internet that may provide similar performance, although we have not had the opportunity to test those. We do NOT profit from the sale or use of Information Unlimited's power-supplies.

The reader assumes all risk for any damage or injury sustained while working with HV and Lifter technology. Working with high-voltage equipment can produce dangerous or deadly shocks, and modifying electrical-equipment may also pose a fire-risk. Please consult our safety-guide for additional information.
