AC/DC converters are a type of power conversion device that modifies the voltage or frequency of electrical power from either an alternating current (AC) or direct current (DC) source. Universal Input, Programmable, Multi-output (PM1-03B-28-G) products are a type of AC/DC converter that are used for multiple DC output voltage levels over a wide input voltage range. This article provides a detailed overview of the applications and working principle of the PM1-03B-28-G AC/DC converters.

Applications of PM1-03B-28-G AC/DC Converters

The PM1-03B-28-G AC/DC converter is typically used in power management applications, such as for providing power in the automotive, telecom, and medical industries. It is commonly used as a standalone primary power supply for providing multiple DC output voltage levels for a range of applications, including computers, process equipment, and test equipment. With its high power levels, the PM1-03B-28-G AC/DC converter can provide power to many electronics devices and critical systems.

Other applications of the PM1-03B-28-G AC/DC converter include providing power to industrial and domestic white goods, safety alarm systems, and medical equipment. It is also used in uninterruptible power supplies and other communication systems, as well as for various industrial and home automation applications.

In addition, the PM1-03B-28-G AC/DC converter is often used in wind turbines and solar systems for their high power levels and universal-input capability. Furthermore, it is designed for use in applications that require multiple output voltage levels, such as server racks, LED driving, broadcast, and other systems.

Working Principle of PM1-03B-28-G AC/DC Converter

The PM1-03B-28-G AC/DC converter is designed to provide multiple DC output voltage levels from a single-phase or three-phase AC input. It consists of a high-frequency switching power supply that provides the necessary power for the DC output voltage levels. The input voltage is passed through a power factor correction (PFC) stage to reduce harmonic distortion and instability at the input. The corrected input voltage is then passed through a full-bridge rectifier to generate a high-voltage DC bus.

The high-voltage DC bus is rectified to a lower voltage level, regulated to a constant output voltage, and then conditioned through a filter circuit. The output is then monitored by the converter’s microprocessor in order to ensure stability and accurate regulation of the output voltage. Depending on the application, the output voltage can be adjusted by setting the voltage divider. The output is also monitored for temperature, overload, short-circuit, and over-voltage conditions.

The PM1-03B-28-G AC/DC converter is designed for use in applications that require multiple output voltage levels, such as server racks, LED driving, broadcast, and other systems. It is an efficient and reliable device that is capable of providing stable and accurate output voltages across a wide range of input voltages. Additionally, it is designed to operate without the need for an external heat sink, which eliminates the need for additional cooling hardware.
