AC DC Converters are important pieces of technology that can be found in a variety of applications. The VMS-180-12 is one such type of AC DC Converter that is used primarily in applications such as medical and automotive. Before discussing the application field and working principle of the VMS-180-12, it is important to understand the basic operation of an AC DC Converter.

An AC DC Converter is a device that converts alternating current (AC) to direct current (DC). In a direct current electrical power system, the electrical polarity remains constant and the voltage and current are consistent. Meanwhile, in an alternating current electrical system, the voltage and current will change periodically as the current alternates between positive and negative polarity. Therefore, in order to convert AC to DC, the AC signal must be “rectified”, or converted to a series of positive and negative pulses. The AC DC Converter then rectifies these pulses into a single, consistent DC current that can be used for various applications.

Now that we have a better understanding of AC DC Converters, let us look at the VMS-180-12. This type of AC DC Converter is primarily used in medical and automotive applications. In medical applications, the VMS-180-12 is used to supply medical equipment and devices with consistent and reliable DC power. For example, it can be used to power medical diagnostic tools, critical care monitors, and other medical equipment. In automotive applications, the VMS-180-12 is used to power automotive electrical systems such as the battery, lights, and other electronic components.

The VMS-180-12 is an isolated AC DC Converter that can take in single-phase, three-phase, or four-phase input. It features a voltage range of 180-360V AC for both AC and DC outputs, and it can deliver up to 1000W of power. The device is highly efficient, with efficiency ratings of up to 97%. It also has advanced protection features such as over-voltage, over-temperature, short-circuit, and over-current protection to ensure maximum safety.

In terms of working principle, the VMS-180-12 follows a three-stage conversion process. First, the AC signal is rectified to a series of pulses. Next, these pulses are converted to a pulsed DC signal. Finally, the pulsed DC signal is filtered and regulated to produce the desired DC output. This conversion process occurs in the controller IC of the device, which is then controlled and regulated by the embedded software in the AC DC Converter.

To sum it up, the VMS-180-12 AC DC Converter is a highly efficient device that is used primarily in medical and automotive applications. It has a wide input voltage range and can deliver up to 1000W of power. The device follows a three-stage conversion process to convert AC to DC, and it is protected by advanced protection features for maximum safety.
