SDI12-9-UD2-P5R

The SDI12-9-UD2-P5R is an AC DC desktop and wall adapter that is equipped with high-quality safety measures, and is suitable for an array of applications. This AC DC adapter features a universal output voltage and current, an auto-restart function in the form of over-voltage, and over-current protection, and other protective features such as over-temperature protection and a voltage drop indicator. The SDI12-9-UD2-P5R provides reliable conversion of energy input from AC, DC, or other sources, and can be used with a variety of electronic devices.

The working principle of the SDI12-9-UD2-P5R is based on controlled semiconductor rectification and voltage regulation. When the power source that supplies the AC voltage is connected to the input terminals, the input AC voltage is rectified, filtered, and directly applied to the switch-mode converter, where the converter transfers the energy at a higher frequency.

The cycle of switching on and off of the switching device is controlled by pulse width modulation, or PWM. This PWM method is a highly efficient energy conversion technique, as it ensures a significant reduction in losses caused by the system components. Therefore, the power generated by the AC DC desktop and wall adapter is converted to DC voltage and current with greater efficiency than other power conversion methods.

The output of the AC DC adapter is then adjusted according to the desired voltage and current. The output is controlled by the adjustable keypad or other pre-programmed devices, and also protected by a built-in circuits to prevent any overload or short-circuit conditions. The device has a wide input voltage and current range, and can accept power from a range of sources, such as AC, DC, or even other types of energy sources.

The high quality safety features of the SDI12-9-UD2-P5R make it ideal for an array of applications, both residential and industrial. The adapter is designed to operate in an environment with temperatures ranging from 0°C to +70°C. In addition, the device is rated for 20 Amp current and provides an impressively low ripple. This makes it suitable for applications requiring various voltages, currents, and load types, such as laptop chargers, LED and LCD lighting, and electric machines.

Overall, the SDI12-9-UD2-P5R is an excellent AC DC desktop and wall adapter that provides efficient, safe power conversion for a variety of applications. Its advanced protective features, combined with its wide input voltage and current range, makes it a great choice for both residential and industrial applications.
