ELECTRICAL SPECIFICATION:(25℃)

1. Unique EI-type core structure: the “EI” in EI19 refers to its core structure made of E-type and I-type silicon steel sheets laminated together, this structure can effectively enhance the integrity of the magnetic circuit, reduce magnetic leakage phenomenon, and then improve the magnetic coupling efficiency of the transformer, to ensure that in the low-frequency environment, the power can also be efficiently transmitted and converted.

2.1:1 turns ratio: the transformer has the same number of turns in the primary and secondary windings, which means that it will not change the magnitude of the voltage, and its main function is to realize the electrical isolation between the circuits, which can effectively prevent the electrical interference of the primary circuit and the potential voltage spikes from affecting the secondary circuit to ensure the safe operation of the equipment.

3. Suitable for low-frequency applications: especially designed for low-frequency scenarios, it performs well in low-frequency fields such as audio power amplifiers, industrial control, etc. It can stably transmit low-frequency signals or power, ensure signal integrity and stability, reduce signal distortion, and meet the strict requirements of low-frequency signal processing in these applications.

4. Good electrical isolation performance: With 1:1 turns ratio and reasonable structural design, it provides reliable electrical isolation between primary and secondary circuits, which not only protects sensitive equipment from electrical interference, but also enhances the stability and reliability of the whole system and reduces the risk of circuit failure.

5. Compact size: The “19” in the model number generally represents the size specification of the iron core, and the overall presentation of a compact size, which is easy to install and layout inside the equipment with limited space, especially suitable for application scenarios with strict requirements on the size of the equipment.
