MPS03A-120-R is a type of AC DC desktop wall adapter. It is mainly used to supply power to desktop and wall-mounted devices in need of 12V DC and it can work with multiple output voltages. The output voltage is adjustable via an up/down switch. It works by connecting the AC inlet to the power grid. AC power is then converted to DC voltage by a power switch module located inside the casing. This power switch module switches the power on and off to the connected device in order to provide the desired output voltage.

Design and Structure of PSM03A-120-R

The PSM03A-120-R is designed with a chassis that measures 125x84x45mm(LxWxH). It contains dual voltage selectors to select the output voltage. The top of the chassis features an input socket for receiving AC power from the power grid. There are two supply output sockets mounted on the front side which provide a total of 12V of power for the connected device(s). The power switch module and associated components are generally integrated on the bottom of the chassis. This allows for ease of use and installation.

Functionality of PSM03A-120-R

The PSM03A-120-R is capable of working with a range of input voltages. It can operate with an input range of 85-250V AC with a maximum input power of 60W. The dual voltage selector on the device can be used to select desired output voltage between 9V and 12V. It also features overload/short circuit protection to ensure the safe operation of the device. It is designed to work with both desktop and wall mounting devices with an efficiency of 85%.

Conclusion

The PSM03A-120-R is a reliable and efficient AC DC desktop wall adapter designed to supply power to desktop and wall-mounted devices requiring 12V DC. It is capable of working with an input range of 85-250V AC and produces an output voltage range of 9V to 12V. It features dual voltage selectors for ease of use and overload/short circuit protection for a safe operation.
