AC DC Adaptor 12v

AC-DC Adaptor 12V is a Power Adapter that converts alternating current (AC) to direct current (DC) with an output voltage of 12 volts (V). This adapter is widely used in various electronic devices that require a stable low-voltage DC power supply.

During the charging process, household power is usually AC, while many electronic devices, such as some models of routers, surveillance cameras, LED light strips, etc., require 12v DC to power or charge. Therefore, the 12v AC DC Adaptor is responsible for converting AC to 12v DC suitable for these devices. This conversion process is achieved through the electronic components and circuits inside the adapter.

Main function: To achieve the conversion of AC to 12v DC, and provide stable DC power for electronic devices with specific voltage requirements.

Application: Widely used in various electronic devices that require 12v DC power supply, including but not limited to routers, surveillance cameras, LED light strips, some small household appliances, etc.

Importance

Ensure the normal operation of the device: 12v AC DC Adaptor provides stable DC power to the device to ensure that the device can work normally or charge.

Protect the device: The design and manufacture of the adapter requires precise control of current and voltage to prevent the device from being damaged due to power problems. Therefore, choosing a high-quality and stable adapter is crucial to protect the device.
