EMH350PD21-EF Power Supplies - External/Internal (Off-Board)

AC DC Converters

AC/DC converters are a type of electronic device that converts AC (alternating current) into DC (direct current). The EMH350PD21-EF AC DC converters are typically used when direct current is required for industrial and commercial applications, such as lighting, motor control, and power supply. The EMH350PD21-EF AC DC converter is a device that efficiently converts single phase AC to DC current. This makes it perfect for usage in applications that need single phase input voltage.

The EMH350PD21-EF differs from other single phase AC to DC converters in that its an open-loop configuration and has a fast response time. This allows it to provide a more efficient and accurate conversion of AC to DC, resulting in a higher quality output power. The EMH350PD21-EF also features current regulation and voltage accuracy, which can be further optimized by adjusting the control parameters. Additionally, this converter has no need for an external capacitor as it has integrated storage capacitors to store energy.

To operate, the input voltage is applied to a full-bridge rectifier which converts the AC voltage to a DC. Afterwards, an inductor is used to filter the pulsated rectified output voltage to make it more suitable for other DC components. The inductor, in combination with the input capacitor, produces an LC filter which reduces the ripple voltage and further boosts the DC output. Then, a flyback converter transforms the DC voltage from the LC filter into the desired output.

The converter works in a flyback topology, which is a switching regulator configuration. It uses a transformer to transfer energy between two separate circuits. When switching is enabled, the secondary winding of the transformer is sprayed with energy through the primary winding, resulting in a change in voltage and current. As this occurs, the secondary winding produces a potential difference between its two outputs which can be used to power other electronic components.

The EMH350PD21-EF can be used for a variety of applications. Its capable of providing power to a range of loads, like motors, air compressors, programmable logic controllers, rectifiers, and pumps. It can also be used in applications which require more reliable and accurate power, such as in medical applications, robotics, and industrial automation. Due to its compact size, it’s a great option for use in households.

When it comes to industrial applications, the EMH350PD21-EF is a great choice due to its efficiency and fast response time. It can be easily integrated into existing systems, and its control parameters can be quickly fine-tuned to suit specific requirements. The EMH350PD21-EF makes the process of converting AC to DC current simple, efficient, and reliable.
