About Customized China AC-DC Power Supply
How to choose AC or DC?
Choosing between using DC and AC depends on the purpose and requirements of the project. Due to the nature of the battery to be powered by direct current, it is recommended to use direct current to power electronic devices. On the other hand, the ease of AC voltage modulation remains unmatched.
Why don’t households use direct current?
Direct current is not used in the home because for the same voltage value, direct current is more lethal than alternating current because direct current does not pass through zero. Electrolytic corrosion is more of a problem with direct current.
The right AC adapter for your device is one with matching electrical ratings. The input voltage and current of the device must match the output voltage and current of the adapter.
AC power is easier to step down, so it is used in wiring applications such as mains wiring. Apart from residential applications, AC power is mainly used in industrial machines such as packaging machines and other smart device manufacturing. On the other hand, solar panel applications (photovoltaic cells) typically use DC cables.
