The distinctive feature of Class 2 transformers is their ability to provide a secure power source by ensuring that the output voltage remains within a predefined and safe range, thereby preventing electrical shock and safeguarding sensitive equipment.
Class 2 transformers contribute to operational efficiency by adapting to the specific power requirements of connected devices, minimising energy consumption and reducing wastage.
Choosing the right transformer involves considering factors, such as the power requirements of your devices, the voltage specifications of the transformer and any specific features needed for your application.
