Many people, when they’re not familiar with waterproof transformers and rainproof transformers, might mistakenly think these two types are identical. In fact, whether from the perspective of waterproof rating or from the standpoint of performance and application scenarios, there are significant differences between the two. 1. Differences in Protection Ratings: Waterproof transformers have high waterproof ratings ranging from IP67 to IP68, which can completely prevent dust from entering and allow them to be submerged in water for extended periods. Rainproof transformers, on the other hand, have a waterproof rating of IP44, which only prevents solid objects larger than 1mm from entering (dust protection) and ensures that liquids splashed onto the enclosure from any direction won’t cause damage or affect its performance (rain protection). 2. Different Application Scenarios: Waterproof transformers are typically used more frequently in lighting applications, such as underwater lights, buried lights, fountain lights, and large-scale outdoor illumination projects. Rainproof transformers, by contrast, are generally suitable for building illumination, nighttime landscape lighting, guardrail tubes, digital displays, and other similar lighting projects, making them the preferred power supply choice for outdoor products.
