Safety transformer TR 308 413091

Safety transformer – reliable power supply for intercoms and doorbells

This modular safety transformer TR 308 is a compact and efficient solution for powering intercoms, doorbells and other devices requiring safe, reduced voltage. Designed for easy installation and reliable operation, it is suitable for both new installations and modernization of existing systems. Its versatility will be appreciated by both professional installers and end users.

Design and application

The TR 308 transformer is a typical doorbell transformer designed for surface or flush mounting. Its modular design (2 module width) allows for easy adaptation to existing distribution boards or enclosures. It has two secondary windings – 12V and 8V – which increases its flexibility and allows powering various devices. Built-in overload protection protects the transformer from damage in the event of a circuit overload, and also ensures safe system operation. Therefore, in the event of a problem, the transformer will automatically switch off and cool down before restarting.

Key features and benefits

• Versatility: Two secondary voltages (12V and 8V) allow powering a wide range of devices.
• Safety: Short-circuit protection protects the installation and devices from damage.
• Modular design: Facilitates mounting in distribution boards and enclosures. 2 module width ensures compact dimensions.
• Durability: Made of high-quality insulating materials, ensuring long-lasting and reliable operation.
• Compliance with standards: Meets the requirements of IEC 61558-2-6 and IEC 61558-2-8 standards, guaranteeing safety of use.
• Easy installation: Possibility of mounting on TH35 rail or directly to a flat surface using screws.
• Output power: The maximum output power is 8W, which is sufficient for most standard doorbell and intercom applications.

The TR 308 transformer is a solid choice for anyone looking for a reliable and safe solution for powering doorbell and intercom systems. Its compact dimensions and ease of installation make it an ideal solution for both professionals and DIY enthusiasts.
