A standard NST takes your wall outlet voltage (usually 120V or 240V) and steps it up to anywhere between 2,000 and 15,000 volts. Because they are "current-limiting" devices, they are designed to maintain a steady flow of electricity (typically 30mA or 60mA) even as the resistance of the gas changes. Types of Transformers
Always ensure the unit is UL-2161 compliant. This standard requires "Secondary-Circuit Ground-Fault Protection," which shuts the power off if the electrical current leaks to the ground. buy neon sign transformer
In summary, the transformer is the heart of any neon display. While the glass provides the art, the transformer provides the energy, making it the most important technical component to get right for both performance and safety. A standard NST takes your wall outlet voltage
