EPSA120050UE-P6RP-EJ is a kind of AC/DC desktop, wall adapters, and belongs to the industry-standard group of wall mount power supplies. Being extremely reliable and easy to use, it also comes in multiple size and input/output configurations.

Application Field

Since it provides output power higher than 12W and accepts input voltages of 90-264VAC, EFSA120050UE-P6RP-EJ is suitable for a wide range of applications in commercial and consumer electronics. Its applications include power adapters for factory/process automation, consumer electronics, communication equipment, medical devices, and other typical AC-DC power supplies.

Working Principle

EPSA120050UE-P6RP-EJ is designed to use a universal power input with auto-range from 90-264VAC to provide reliable and efficient power conversion from AC to DC. It is consisted of several major parts, including a power factor corrector, isolation transformer, rectifier bridge, main switching transistor, control circuitry, and more.

When the power adapter is connected to an AC source, the power factor corrector will first step down the voltage and clean the power line and send the signal to the isolation transformer, which provides electrical isolation against current path. The rectifier bridge will then convert the alternating current to direct current. The final step is conducted by the main switching transistor (MOSFET), which will control the output voltage and current flow. The entire process is monitored and adjusted by the control circuitry.
