ME120A1251N01 Application Field and Working Principle

Overview

ME120A1251N01 is an AC/DC desktop, wall adapter from MEAN WELL. It is a single output, adjustable voltage low power adaptor with 85~264VAC universal input, which meets the latest safety frequency regulations. This connector has a power range of 12W and an output voltage of 1.3~5V adjustable, which not only can apply in most of occasions, but also is widely compatible.

Application Field

ME120A1251N01 has a universal input, and its output voltage of 1.3~5V is adjustable with constant current control. Therefore, it can be used to power a wide range of electronic devices, such as laptop adapters, LED lights, CCTV cameras, networking & communication devices. With the protection of its overload current protection, short circuit protection, over temperature protection and built-in fan function, it provides safety assurance in cases of any emergency.

Working Principle

ME120A1251N01 works by regulated switching DC/DC converter with OSL (Over load protection). Its internal circuit of input rectifier, low harmonic boost, SR (Soft Recovery) controllers, inductor and capacitor are all built inside of the machine. When working, voltage is first converted into a 70~25Khz frequency and the signal is then sent to the switching regulator and controlled by the control IC. Then the output voltage regulator is transformed rectified into AC, which is then sent to the output side, leaving a stable DC voltage .

Conclusion

ME120A1251N01 is designed to be used as an AC/DC desktop, wall adapter from MEAN WELL. With its adjustable voltage of 1.3~5V, and its universal input of 85~264VAC, ME120A1251N01 is able to power a wide range of devices and provide high safety assurance with protection of its built-in fan, overload current protection, short circuit protection and over temperature protection. WORKING by its own regulated switching DC/DC converter with OSL, ME120A1251N01 is a highly reliable and versatile power source.
