Core Type EI 30/5: This indicates the core type and size of the transformer, with EI being a common design for laminated core transformers. The "30/5" likely refers to the dimensions or specifications of the core.
Power - 0.5VA: This transformer has a power rating of 0.5 Volt-Amps (VA), which is a measure of apparent power. It gives an idea of the maximum power capacity it can handle without overloading.
Input voltage - 230V or 115V, 50/60Hz: This transformer is designed to work with different input voltages, making it versatile. It can accept either 230 volts or 115 volts AC, and it's compatible with both 50Hz and 60Hz frequency inputs.
Insulation class - Class B (130°C): The insulation class indicates the maximum allowable temperature rise for the transformer. Class B means it can withstand temperatures up to 130 degrees Celsius without degrading.
Ambient temperature (ta) - 70°C: This is the maximum ambient temperature at which the transformer can operate safely. It's rated for operation in environments with temperatures up to 70 degrees Celsius.
Dielectric strength - 4,500Vrms: This parameter specifies the voltage at which the transformer's insulation can withstand without breaking down. In this case, it can handle up to 4,500 volts root mean square (Vrms).
Inherently short-circuit-proof: This is a safety feature that means the transformer is designed to handle short circuits without causing damage. It will not pose a risk even if a short circuit occurs in the connected equipment.
Self-extinguishing material: The use of self-extinguishing materials ensures that the transformer is made from materials that will not sustain combustion, enhancing safety.
Potted under vacuum: "Potted" means the transformer is encapsulated or sealed with a protective material. The fact that it's done under vacuum ensures that the potting material completely fills the enclosure, protecting the internal components from moisture and contaminants.
Weight: 43g: This is the weight of the transformer, which is relatively lightweight.
In summary, the YZ30S05-2407B EI 30 0.5VA 230V Low-Frequency Encapsulated Transformer is a compact and versatile transformer suitable for a range of applications, including power supply units, household appliances, and audio equipment. Its key features include its power rating, compatibility with different input voltages and frequencies, high-temperature tolerance, safety features like short-circuit protection, and the use of self-extinguishing and vacuum-potted materials for safety and reliability.
