EPSA120200U-P5RP-SZ

EPSA120200U-P5RP-SZ AC/DC desktop, wall adapters are commonly used for a variety of applications such as charging laptops, powering household and office devices, charging cell phones, and many other applications needing DC voltage. In order to meet the power requirement for these applications, the EPSA120200U-P5RP-SZ AC/DC adapter features a high power density and low output ripple, making it an ideal choice for computing, audio/video, and medical devices.

The EPSA120200U-P5RP-SZ adapter is an isolated-type AC/DC adapter that consists of an AC/DC converter, an EMI filter, an AC line filter, and output terminals. The AC/DC converter is a switching-type power supply that converts the AC mains voltage (120VAC) into a regulated DC output of 12V and 200W. The EMI filter is designed to reduce the electromagnetic interference from the power supply to the outside environment. The AC line filter is used for suppressing high-frequency noise from the AC mains and the output terminals are used for connecting the load device.

The working principle of the EPSA120200U-P5RP-SZ AC/DC adapter is based on a flyback topology switch mode power supply. Input AC power is directly applied to the primary winding of the power transformer; the current flows through the primary of the transformer and the secondary of the transformer produces the regulated DC output voltage through the auxiliary winding. The switching action of the main switching transistor is controlled by an on-chip error amplifier. The error amplifier compares the output voltage with a DC reference voltage and adjusts the duty cycle of the main switch accordingly to maintain regulation.

The output voltage of the EPSA120200U-P5RP-SZ AC/DC adapter can be adjusted by adjusting the duty cycle of the main switch and by changing the tap of the auxiliary winding. The output ripple of the EPSA120200U-P5RP-SZ adapter is kept low by using an EMI filter in the power supply circuit, which helps to reduce the unwanted noise produced by the switching operations.

The EPSA120200U-P5RP-SZ AC/DC adapter is a finely engineered product with advanced safety features. It provides protection against over current, over voltage, over temperature, and short circuit. It also features a high isolation voltage between the input and outputs that eliminate any chances of ground loop problems. The device is also certified to meet the applicable safety standards set for electronic products, making it an ideal choice for many high-end applications.

In conclusion, the EPSA120200U-P5RP-SZ AC/DC adapter is an efficient and reliable power supply device that can be used to meet the power requirements of many computing and electronic device applications. Its compact size and high power density make it an ideal choice for many consumer and industrial applications. Moreover, with its advanced safety features and wide input voltage range, the EPSA120200U-P5RP-SZ AC/DC adapter provides optimal performance and peace of mind for the end users.
