Class 2 transformer
Foster Transformer Class 2 transformers are ideal for use with touchless faucets and toilets, and are made in the United States to meet Buy American directives. The transformers are easy to install and operate since they require no external fusing and contain no internal current fuses. They are designed for applications requiring a hard-wired, externally mounted Class 2 power source, are UL-listed and C-UL-certified, and are ideal for many control applications.
