Transformer TEZ 4,5/D 230/9-9V 16009-8970

Safety transformer for PCB mounting

This is a small but efficient safety transformer, ideal for applications requiring galvanic isolation and voltage reduction. The TEZ 4,5/D 230/9-9V model from BREVE TUFVASSONS is cast, which ensures its durability and resistance to environmental conditions. Designed for mounting on printed circuit boards (PCBs), making it easy to integrate with various devices.

#### Construction and application

The transformer's construction is based on secondary windings with a voltage of 9V AC, powered by a 230V AC mains voltage. The rated power of 4.5 VA makes it suitable for powering circuits with low power consumption, such as control circuits, low-voltage electronics or LED lighting. Its main function is to provide safe voltage reduction and galvanic isolation between the primary (mains) and secondary (powered) circuits.

* **Cast construction:** Provides high resistance to moisture, dust and vibration – increases reliability in harsh working conditions.

* **PCB mounting:** Enables easy and quick integration with printed circuit boards, which reduces assembly time and improves installation aesthetics.

* **Safety transformer:** Provides galvanic isolation, protecting the user from electric shock and minimizing the risk of equipment damage.

* **Insulation material class B:** Guarantees high electrical and thermal resistance of the winding insulation.

#### Specification and compliance with standards

The TEZ 4,5/D transformer meets the requirements of standards PN EN 61558-1:2000, PN EN 61558-2-1:2000 and PN EN 61558-2-6:2000, which confirms its safety and reliability. It has a protection class of IP00, which means there is no protection against the ingress of solids and liquids – therefore, it is recommended to use it in dry and clean environments. Thermal class Ta60B indicates the permissible ambient temperature during operation.

Compact dimensions – 35 mm wide, 42 mm high and 29 mm deep – make it easy to mount even in limited space. The transformer operates at a primary voltage of 230 V AC and a secondary voltage of 9 V AC, offering a rated power of 4.5 VA. The secondary winding leads are 6-7 and 9-10, and the primary winding – 1-5. The electrical strength of the insulation is 4kV/60s, providing a high level of safety.
