Product Description

Our High Powered UL 2161 Approved Conventional Line Drive Neon Solid State Transformer

This transformer was designed and patented by the owner of Information Unlimited. It was the only design that UL passed on the first submission for the 2161 regs at that time! It was used by the four largest beer and ale companies and is still used today with the amount of over 300,000 pieces in service since its inception.

  • Patented circuitry eliminates mercury migration and restores most darkened displays
  • Patented ground fault safety shut down
  • Includes preset level dimmer switch
  • Many in service for almost 15 years!
  • Size 5-1/2 x 5 x 2-1/4” flame retardant box
  • With pull chain switch
  • 8’ feet 3 wire heavy duty cord
  • 24” GTO flexible output leads
  • Weighs 2 pounds

These current limited and balanced output transformers are excellent for all size neon displays tubes up to 80 feet. Patented circuitry uses our ground fault safety shut down for safe operation. This unit is a high brightness transformer with an honest 10,000 volts open circuit at a short circuit current of 45ma, operating from 115 VAC and drawing 2.3 amps when fully loaded.

When we first built this transformer, we decided to test it with the largest sign we could find at the time, being a fully loaded Harley Davidson display. When first turned on, we noticed the sign's white and green areas had a lot of mercury darkening. As the sign warmed up, the darkening was mostly gone within several hours. We then took some measurements, and found the voltage at 13200(!) and the current 45 ma. The wave shapes were integrated using Simpson rule for verification. The input AC current was over 2 amps. We ran the sign for a week and it totally cleaned up.


Plasma, Gas Discharge, and Jacob's Ladder Power Supplies

High voltage, high frequency current limited power supplies. Balanced output with center point grounded. Intended for laboratory research in the study of plasmas, gas lasers and open arc discharges. Patented circuitry is UL approved with full short circuit, ground fault, and open circuit safety shutdown.
