AC / DC converters are used for power electronics devices to convert alternating current (AC) to direct current (DC) voltage. One type of AC/DC converter is the ZPSA20-5, which is a switch mode power supply. It is a high-efficiency, low-power converter that can easily be used in a wide range of applications.

A ZPSA20-5 converter is an offline switch mode power supply with a built-in dual-output, flyback transformer. It provides a maximum output power of 200W at an input voltage from 85-265 VAC. The converter has a boost-flyback topology, with a frequency of approximately 55kHz. Its output is regulated, with an output voltage range of 3.3V-17V and an output current up to 10A.

The working principle of the ZPSA20-5 converter is based on the same principles of boost-flyback topology. When an AC voltage is applied to the input, the power switch closes and current flows in the primary winding of the transformer. The current creates a magnetic field which then induces a current in the secondary winding of the transformer. When the current is greater than the output current of the load, the transformer produces a voltage in the secondary winding, and a discharge of energy into the output of the converter.

The converter can achieve an efficiency of over 85% due to its high power factor and low output ripple. Its light weight and compact design also makes it easier to install and set up. Additionally, the converter includes an integrated soft-start and overload protection function to ensure safe operation.

The ZPSA20-5 converter can be used in various applications, including servers, UPS systems, LED lighting, computer peripherals, and many other consumer electronics. It can also be used for industrial equipment and automation systems. The converter is capable of providing a constant and reliable power supply, which makes it an ideal choice for many types of applications.

In conclusion, the ZPSA20-5 converter is a versatile, high-efficiency AC/DC converter. Its lightweight design and low power consumption make it ideal for use in a range of applications. Its ability to provide constant and reliable power supply makes it a popular choice for many applications.
