PSA12A-120 Application Field and Working Principle

The PSA12A-120 is a specially designed AC/DC adapter developed for use in small electronic devices, like modern desktop computers, wall adapters, and power supplies. It is a reliable power supply that features short circuit protection, reverse polarity protection, voltage and current overload protection, and active PFC.

The PSA12A-120 is a AC/DC power adapter featuring a wide range of input voltage from 100 to 240 volts so it can be used in any country. It also has a separate adjustable primary and secondary voltage output. The secondary output voltage can be adjusted from 0 to 12 volts and the rated current is 10A up to 120W.

Working Principle

The power adapter is comprised of several components, including a power transformer, a rectifier, a voltage regulator, and filter capacitors. The transformer converts the alternative current from the power line into a lower-voltage DC. The rectifier converts the AC signal into DC current. The voltage regulator then stabilizes the voltage to the output load the power adapter is connected to. The capacitor filter can then further stabilize the voltage and prevent the output voltage from fluctuating.

Application Field

The PSA12A-120 is suitable for use in a variety of small electronic devices, such as desktop computers, wall adapters, and power supplies. It is designed to be mechanically robust with a strong mechanical housing that is able to withstand harsh conditions and is highly resistant to shock and vibration. With its wide range of input voltage and adjustable secondary output voltage, it is the perfect power supply for a range of applications.
