Network transformer TR-24 output voltage 24VA, I=0.5A, output power 12VA

Network transformer for powering electrical and electronic devices

This TR-24 network transformer is a reliable solution for powering devices that do not require stabilized voltage. It is particularly useful in applications where short-term fluctuations in mains voltage are not a problem. Thanks to its construction, this transformer provides galvanic isolation between the primary and secondary circuits, which increases safety.

The TR-24 transformer is mounted on a standard 35mm rail, which facilitates its installation in distribution boards and control cabinets. Its modular design (3 modules, i.e. 52.5 mm wide) allows for efficient use of space. The use of an isolation transformer minimizes the risk of electric shock and interference with the operation of connected devices.

Characteristics and application

The TR-24 transformer is used to power various electrical and electronic devices, such as:

• low-voltage lighting,
• alarm systems,
• intercoms and video intercoms,
• control devices,
• small laboratory equipment.

Its compact dimensions (52.5 mm x 90 mm x 65 mm) allow for mounting even in limited spaces. It has a protection class of IP20, which means protection against touching with a finger and against the ingress of solid objects larger than 12.5 mm – sufficient for most indoor applications. A built-in single thermal fuse protects the transformer from overheating (up to 115°C), but for full protection of the receiver, additional overcurrent protection is recommended on the secondary side (e.g. 1.5A fuse).

Key features and benefits

• Galvanic isolation: Ensures safe operation and minimizes interference.
• Mounting on 35mm rail: Facilitates and speeds up installation.
