AC DC Desktop, Wall Adapters are reliable, cost-effective products for efficient power conversion. Among the range of adapters, the PSAA18U-150-R-CR3 is a popular model that can be used in different applications. Its power source is rated at 18V DC, 150 mA, and its output is rated at 3.3V to 5V DC.

The PSAA18U-150-R-CR3 AC DC Desktop, Wall adapter is perfect for industrial applications, automotive, telecommunications, and consumer electronics, for charging and powering various electronic gadgets. It has a temperature range of -20°C to +60°C, and it is IP65 rated, which means it is protected against dust, water, and other liquids. The wall adapter has an input voltage range of 100–240 VAC, and its output voltage range is adjustable from 3.3V to 5V, with operation up to 32°C. This adapter is one of the best choices for applications such as medical, CNC machinery, miniature robots, and so on where an output power of 150 mA is necessary.

The PSAA18U-150-R-CR3 is an encapsulated, open-style adapter, and it works on both AC 110–240V wall outlets and desktop power supplies. It comes with an onboard bridge rectifier, and a step-down voltage mode circuit. The pin-out configuration is the standard 2x5-pin rectangular configuration. The input terminals are marked “+” and “-”, and are connected to the AC voltage source. The output terminals are marked as “VCC” and “GND”, and are connected to the load.

The operation of the PSAA18U-150-R-CR3 AC DC Desktop, Wall adapter is based on the principle of electrical rectification and regulated DC voltage conversion. This process starts when the alternating current from the AC line source is rectified by the bridge rectifier, and is then sent to the output using an input voltage regulator. The regulator maintains a constant output voltage by controlling the current flow. The output voltage can be adjusted by changing the input voltage or by changing the resistance value in the regulator circuit.

The PSAA18U-150-R-CR3 AC DC Desktop, Wall adapter is an effective and reliable solution for power conversion. It is perfect for applications requiring low output voltage and constant output current. Its efficient operation, high voltage safety rating, and temperature range make it ideal for industrial applications, noisy environments, and a wide range of electronic gadgets.
