1. ABB TS10/12-24 C Safety transformer 230V 10VA 12-24VAC
These transformers are conditionally short-circuit proof. They are equipped with a thermal protection device that automatically restores power when the transformer has cooled down sufficiently. They are ideal for continuous power supply to measuring devices, electronic auxiliary devices (e.g., measurement, video intercom systems, BUS communication), and low voltage circuits (SELV) for bathrooms and showers, lighting, fountains, electro-medical devices, and similar applications.

2. ABB DIN rail transformer
These transformers with extremely low safety voltage (SELV) on the secondary side for safety are suitable for loads that require an interrupted supply.

3. ABB TS 25/12-24 C safety transformer 25VA
These transformers are conditionally short-circuit proof. They are equipped with a thermal protection device that automatically restores power once the transformer has cooled down sufficiently. They are ideal for continuous power supply to measuring devices, electronic auxiliary devices (e.g., measurement, video door intercoms, BUS communication), and low voltage circuits (SELV) for bathrooms and showers, lighting, fountains, electro-medical devices, and similar applications.

4. ABB 121611
These transformers are conditionally short-circuit proof. They are equipped with a thermal protection device that automatically restores power when the transformer has cooled down sufficiently. They are ideal for continuous power supply to measuring devices, electronic auxiliary devices (e.g., measurement, video door intercoms, BUS communication), and low-voltage circuits (SELV) for bathrooms and showers, lighting, fountains, electro-medical devices, and similar applications.
