It operates with universal 90-264VAC primary input and is constructed with an energy-saving power factor of ≥ 0.82. GST18B48-P1J\'s various protections include overload, overvoltage, and short-circuit detection.The primary features of this product include its full range of AC input, Smart Power Management, globalsafety certifications, and various safety features. Concerning its application, GST18B48-P1J is designed to power a wide range of Electronic devices, such as office automation equipment, PDA/Handheld devices, POS terminals, and many other Electronic devices. This device features a universal 90 - 264 VAC primary input and is constructed with the energy-saving power factor of ≥ 0.88. It includes a universal input frequency of +/-10%, enabling a wider range of applications. The adapter also includes energy-saving function and is compliant with global safety standards such as UL, CE, and CB. The product’s family of desktop wall adapters possess overload, overvoltage and short-circuit protection, and can also provide voltage accuracy of between 3 - 5%. These high efficiency adapters have minimum energy losses and are designed for maximum no-load power consumption and minimum operating noise. Additionally, its fully isolated plastic case further reduces the noise and improves EMI performance.In the working principle, the GST18B48-P1J AC/DC Power Adapter takes a universal AC input voltage from 90-264VAC and converts it into a regulated DC output voltage via a bridge rectifier followed by a switching power supply. The rectifier converts the AC voltage by using a combination of diodes to make the voltage available at all times. This rectified voltage is then passed to the switching power supply, which is typically made of a collection of capacitors, resistors, transistors, and diodes. These components work together to step up or step down the rectified voltage based on an internal reference voltage. This reference voltage is typically provided by an integrated circuit, which controls the output voltage of the adapter by altering the duty cycle of the transistors in the power supply. The regulated DC output from the power adapter is then ready to power the connected Electronic device.Overall, the GST18B48-P1J AC/DC Desktop Wall Adapter is an ideal power supply for a variety of Electronic devices. It features a full range of AC input, smart power management, global safety certifications, various safety features, overload protection, overvoltage protection, and short-circuit protection, and produces a voltage accuracy of between 3 - 5%. It can also provide maximum no-load power consumption and minimum operating noise with its fully isolated plastic case and a universal input frequency of +/-10%. It is energy efficient, intelligent, and is the perfect power supply solution for a variety of Electronic devices.
