With the high efficiency and wide input voltage range requirements of power adapters in consumer electronics, as well as the increase in copper, iron and labor costs,

Most of the original linear transformers in this type of power adapter are gradually replaced by switching power supplies, and most of the output power provided is within 100 watts, and the market demand is growing rapidly. Such as electric bicycle battery chargers, small size LCD TVs, laptops, printers,

There are applications for DVD players and set-top boxes, among others. Most of the early power adapters used linear transformers.

Tengdaxing 12v2a power adapter, 12V2A power adapter brand Tengdaxing as a power exchange device, we should also pay attention to its precautions when using, such as what is its nominal voltage,

That is, what is the upper limit of the output voltage of the power supply? There is also a power adapter with the same nominal voltage, the output current is different, can it be used on the same electrical equipment? These are all things that we should pay attention to when using the power adapter. In fact

The power adapter uses an active voltage regulator inside, so the output value is constant even if the circuit voltage fluctuates. The second is the question of whether the power adapter voltage is the same, the output current is not the same, and it can be used on the same device.

Because its basic principle is that a large nominal current can replace a small nominal current. In other words, a power adapter with a large output current can be used on the same electrical device instead of a power adapter with a small output current. This does not contradict our principle of electricity.

The rated voltage of the Tengdaxing 12V2A power adapter is 100-240Vac, the adjustment range is 90-264Vac, and the rated frequency is 50/60Hz.
