AC DC Converters

AC/DC converters, also called AC/DC power supplies, are electrical systems that convert alternating current (AC) into direct current (DC). The EDR-120-48 is one of the most popular models of these converters, with applications in many different industries, including automotive, medical, home automation, consumer, and many more. Its key features include its unique and patented conversion circuit, wide input voltage range, and wide temperature range. In this article, we will look at its application field and working principle.

Application Field

The EDR-120-48 is designed for applications that require medium- to high-power DC/DC conversion, such as power supplies, automation and robotics, medical equipment, and telecom/industrial equipment. It is a popular choice for use in power supplies, since it offers a wide input voltage range (90V-300V), high efficiency (95%), low power consumption, low voltage ridership, and short circuit protection.

The EDR-120-48 is also widely used in medical equipment, automation and robotics, and other consumer applications. Its low power consumption and low voltage ridership make it well suited for use in low-power devices such as CPAP machines, x-ray and ultrasound imaging equipment, and surgical robots. Additionally, its wide temperature range (-20 to 110°C) make it suitable for use in environments that may have widely fluctuating temperatures, such as industrial or automotive applications.

Working Principle

The EDR-120-48 uses a unique and patented conversion circuit to convert AC to DC power. The unit consists of a primary input stage, rectification stage, EMI suppression stage, and output stage. The primary input stage converts AC voltage to a DC voltage. This voltage is then rectified by the rectification stage, which is comprised of a bridge network of four diodes. The EMI suppression stage consists of a transformer, filter, and capacitors, which removes any unwanted interference. Finally, the output stage consists of a voltage regulator, which controls the DC voltage output to ensure that it is consistent and stable.

In summary, the EDR-120-48 AC/DC converter is a popular choice for applications that require medium to high power DC/DC conversion. It is well suited for use in power supplies, medical equipment, automation and robotics, and other consumer applications, due to its wide input voltage range, high efficiency, low power consumption, and its wide temperature range. Finally, the unit uses a unique and patented conversion circuit, consisting of four stages, that converts AC voltage to a stable and consistent DC voltage.
