What is Switching Power Supply?

Industrial power supply, also known as a switching power supply, switch mode power supply, or switch converter, is a high-frequency power conversion device.

As a trustworthy switching power supply supplier, we produce high-quality switching power supplies. A switching power supply is a specialized electronic device that efficiently converts and delivers electrical power, ensuring stable and dependable energy transmission. It is favored in various industries for its high efficiency, compact size, and ability to provide versatile voltage outputs.

Types of Switching Power Supplies

Omch offers a range of switching power supplies, each designed for specific applications.

 

Our switching power supplies (SMPS) are classified into different series: S (single-phase output), D (dual-group output), T (triple-group output), Ms and Lrs (compact series), DR, NDR, EDR, MDR (DINrail series), and FYS (waterproof series). These options offer versatility that can meet a wide range of power supply needs.

As a professional supplier of switching power supply products, we continuously monitor market demands, stay informed about industry innovations, and are dedicated to ongoing optimization and development of new products, addressing the global demand for high-quality and affordable switching power supplies.

How it Works

A switching power supply (SMPS) employs rapid high-frequency switching to transmit power. It starts by rectifying and filtering the input voltage, transforming it into a high-frequency pulse sequence. Afterward, the voltage undergoes another round of rectification and filtering before reaching the output.

Its function is to convert voltage aligned in bits, utilizing various architectural forms, into the voltage or current required by the user. A switching power supply typically takes AC input (e.g., mains) or DC input and provides DC output to devices, such as personal computers, facilitating voltage and current conversion between the two.
