Custom Neon Sign Guide (1): How to Select a Safe Transformer Power Supply?

When selecting high-quality neon signage, the primary consideration should be choosing a safe and reliable transformer power supply. Selecting the right transformer power supply is crucial as there is a wide range of products with varying quality levels on the market. To cut costs, some manufacturers may use uncertified transformer power supplies, which can lead to safety hazards and other issues, increasing the risks and costs during usage. Therefore, it is crucial to select a high-quality LED neon sign that is both safe and reliable to avoid unnecessary troubles later.

Common Issues and Risks

In many LED neon sign transformers, there are generally three main issues:

1), Safety Hazards

Many low-cost transformer power supplies overlook basic safety measures. Their power wire connections are often exposed, which not only increases the risk of short circuits but also the risk of electric shock, particularly in environments easily accessible to children or pets.

2), Need for Electrical Knowledge

Customers are required to have some electrical knowledge to connect the wires themselves. This not only adds complexity to the installation but also poses safety risks, especially when non-professionals are handling the wiring, leading to poor connections and increasing the risk of electric shock or fire. Hiring a professional electrician to do the installation adds extra costs.

3), Noise Issues

Because these low-cost transformers do not use sealant to encase the internal circuits, a fan must be used for cooling. This not only consumes more energy but also generates continuous noise, affecting the comfort of the environment, especially in places where quiet is needed, such as offices or homes.

High Standards for LED Neon Sign Transformer Power Supply

1), UL and CE Certification

High-quality transformer power supplies must pass rigorous UL and CE certifications. This means they adhere to high safety standards and quality controls during the design and production process, ensuring safety and reliability for users.

2), Fully Sealed Electronic Glue Encapsulation

High-quality transformers use electronic glue to fully encapsulate the internals, completely isolating the circuits from external elements. This not only effectively prevents the ingress of dust and moisture, extending the lifespan of the product, but also greatly reduces noise due to heat dissipation needs.

3), Plug-and-play

High-quality neon signage should be plug-and-play, without the need to hire a professional electrician for wire connections. Generally, LED neon sign power supplies with UL and CE safety certifications do not require manual wire connections, nor do they have exposed wire joints.
