AC DC Converters

An AC DC converter is an electronic device that converts alternating current (AC) to direct current (DC). This type of power supply is usually used in applications such as computers, televisions, and other electronic devices where it is necessary to convert a voltage supply from AC to DC.

The SHP1000PS48 is a high-performance AC DC converter with an output voltage of 48Vdc, a wide input voltage range of 85-264VAC, and an excellent power factor (PF) of >0.95. It features a switching frequency of 53kHz, allowing for a very high efficiency of up to 96%. The SHP1000PS48 has integrated over voltage protection and short-circuit protection, making it suitable for use in harsh environments.

Application field and Working Principle

The SHP1000PS48 is an ideal solution for a wide range of applications, such as industrial machines, medical equipment, lighting, power systems, energy storage equipment, and more. The device is capable of providing a regulated DC output voltage from AC input sources, including single- or three-phase utility AC mains.

The SHP1000PS48 works on the principle of a full-bridge active clamp topology. It consists of four active components, such as an MOSFET and rectifier, which are connected in a bridge arrangement. During the first half of each cycle, the MOSFET acts as a rectifier and during the second half, it behaves as a clamp, thereby reducing the switching losses and improving the performance.

The SHP1000PS48 also features an advanced digital control that ensures stable and precise voltage output. It monitors the output voltage and current continuously, enabling it to maintain a high degree of output regulation. In addition, the device has an intelligent standby mode, which allows it to enter into standby mode when the output is not being used, resulting in lower power consumption and longer product life.

The SHP1000PS48 is highly reliable and RoHS compliant. It has an operating temperature range of -40°C to 85°C, enabling it to operate in a wide range of environmental conditions. It is also highly efficient, allowing for a cooler operating temperature and reducing the energy expenditure.

The SHP1000PS48 is an ideal solution for applications requiring an AC to DC converter with high power efficiency, stability, and long operational lifetime.
