PSA120U-120 Application Field and Working Principle

The PSA120U-120 AC/DC desktop, wall adapters are widely used in various fields and applications. It is perfect for emerging application needs, including medical, security systems, automotive, consumer electronics, wireless communications, and LAN/WLAN applications. It provides reliable power, reliable performance, and high efficiency.

The PSA120U-120 AC/DC desktop and wall adapters offer a wide input range from 90V AC to 264V AC. The universal input voltage acceptance makes it ideal for harsh power environments. It also provides a wide output range from 3V to 20V DC, with a high power rating of 120 watts. There are four different models available: PSA120U-48D, PSA120U-72D, PSA120U-96D, and PSA120U-120D.

The PSA120U-120 AC/DC adapters are equipped with a temperature compensated fan speed controller, a short-circuit protection circuit, and an over temperature protection circuit. The built-in part is temperature compensated to ensure that the output voltage is stable over a wide range of temperatures and an over temperature protection circuit which prevents damage to the circuit due to an overheated environment. Additionally, the short-circuit protection circuit helps protect the adapter from short circuits and over current damage by shutting down the output when current is detected.

In terms of performance, the PSA120U-120 delivers high efficiency with a low standby power consumption and low output ripple and noise levels. It is also designed for low inrush current for safety and to reduce the start-up time of the system. With its noise-free operation, the PSA120U-120 is ideal for noise sensitive applications. Additionally, it is also approved for use in medical grade applications.

The main working principle behind the PSA120U-120 AC/DC desktop, wall adapters is based on the use of a power converter. This converter changes the input AC voltage from 90V to 264V AC to a predetermined DC output voltage. The DC output voltage is then regulated by a feedback circuit that compares the actual output voltage with the predetermined setpoint voltage. If the output voltage falls below the setpoint voltage, the converter will boost the output voltage and if the output voltage is above the setpoint voltage, the converter will reduce the output voltage.

Overall, the PSA120U-120 AC/DC desktop, wall adapters provide reliable power, reliable performance, and high efficiency for a wide range of applications. With its temperature compensated fan speed controller, short-circuit protection circuit, and temperature protection circuit, the PSA120U-120 is a safe and reliable option for any application.
