Title: Understanding UL 60335-2-142: Safety Standard for Portable Transformers and Similar Products

Portable transformers and other similar products are essential for powering various home appliances in our daily lives. However, these products can pose significant safety risks if not designed, manufactured, and used properly. To mitigate these risks, Underwriters Laboratories (UL) has defined a safety standard for portable transformers, power supplies, battery chargers, and similar products designed for household use, which is known as UL 60335-2-142.

What is UL 60335-2-142?

UL 60335-2-142 is a safety standard published by UL, which outlines the safety requirements for portable transformers, power supplies, battery chargers, and similar products designed for household use. The standard specifically covers the safety requirements for portable transformers, which are used to convert electrical power from an AC power source to a DC power source for portable devices.

UL 60335-2-142 aims to ensure the safety of consumers when using portable transformers and other similar products. It sets forth specific guidelines for manufacturers to follow in order to prevent potential hazards such as electric shock, fire, or mechanical injuries. To comply with this standard, manufacturers must design and produce their products in a way that minimizes risks associated with electrical components, wiring, insulation, temperature rise, and other potential dangers.

Key Requirements of UL 60335-2-142

UL 60335-2-142 has several key requirements that manufacturers must comply with in order to ensure the safety of their products. These requirements include:

Electrical Safety: Manufacturers must ensure that their portable transformers and other similar products are designed and manufactured to minimize the risk of electrical shock, fire, or mechanical injuries. This involves ensuring that electrical components are appropriately insulated, that wiring is correctly installed and grounded, and that other electrical hazards are minimized.

Fire Safety: Manufacturers must ensure that their portable transformers and other similar products are designed and manufactured to minimize the risk of fire. This involves ensuring that electrical components are appropriately insulated, that wiring is correctly installed and grounded, and that other fire hazards are minimized.

Temperature Rise: Manufacturers must ensure that their portable transformers and other similar products are designed and manufactured to minimize the risk of temperature rise, which can lead to overheating or other safety hazards. This involves ensuring that electrical components are appropriately insulated, that wiring is correctly installed and grounded, and that other temperature-related hazards are minimized.

Product Performance: Manufacturers must ensure that their portable transformers and other similar products are designed and manufactured to meet or exceed the relevant performance standards and requirements. This involves ensuring that the products are capable of handling the intended loads, and that they are free from defects and other issues that could affect their performance.

Conclusion:

UL 60335-2-142 is an essential safety standard for portable transformers and other similar products designed for household use. By following the key requirements outlined in this standard, manufacturers can ensure that their products are safe for use in a variety of household environments, while still meeting the relevant performance and safety standards. As a consumer, it is important to carefully select and use portable transformers and other similar products, and to follow the relevant safety guidelines and requirements outlined by UL.
