Brand Power Adapter

What is the core part of the power adapter?

Power adapter is a charging device that converts external AC power into DC power, commonly used in cell phones, laptops, monitors and other various household appliances, so which component is its core part? What role does it play in the adapter?

The function of the power adapter is to convert the external current and voltage into the current and voltage applicable to electronic equipment, naturally its core part is the transformer. Transformer is a kind of soft magnetic electromagnetic components, the main function is power transmission, voltage conversion. Now let's talk about the change of rated voltage when it works.

Rated voltage has primary rated voltage and secondary rated voltage two kinds. Transformer in the rated operating conditions, to achieve the transformer insulation strength and temperature rise specified by the effective value of the primary voltage. That is to say, in the specified range, the maximum effective voltage added to the primary winding of the transformer. The secondary rated voltage is the effective value of the secondary output voltage when the primary is loaded with the rated voltage and the secondary is no-load. Overall, the rated power supply is the voltage permitted to be applied to the coils of a transformer, which must not be greater than the specified value during operation.

Eahunt power adapter has built-in eightfold protection such as over-current and over-voltage, six-level energy efficiency, and more than 200 international certificates such as UL, CCC, GS, PSE, CE, FCC, etc. The quality is up to the standard, the charging is safe, and it can be directly exported to the international market.
