Zamel ETZ series electronic transformers

The ETZ series electronic transformers, by Zamel, are intended to work with halogen (and selected LED) light sources in modern, energy-saving interior design in plants, industry, offices and households.

The transformers are supplied with the typical mains voltage of 230 VAC (connected using screw terminals). The nominal output voltage is 11.5 VAC. Depending on the model, installation contractors can choose models with a maximum power of 50, 60, 70, 105, 150, 210 or 250 W (the maximum output current from 4.3 to 22 A).

The series features overtemperature protection (triggered by a temperature above 100°C), short-circuit protection and overload protection. In the case of the first two, the switched-off converter automatically returns to normal operation after cooling down/removing the short circuit. The products are designed for surface mounting and can work in an environment with a maximum temperature of 40°C.

The electronic transformers have the ability to work with intelligent dimmers and with small loads (from 0 W), which occur when powering some LED light sources. In addition, the products comply with the international standards EN 60598 and EN 61347 (general and safety requirements for lamp control gear), EN 61547 and EN 61000 (electromagnetic compatibility requirements), and EN 55015 (radiofrequency disturbances from all lighting equipment).
