The Switch Mode Power Supply (SMPS) is an advanced power conversion solution designed for high efficiency and reliable performance. With wide input voltage support, compact size, and built-in protections, SMPS is the preferred choice for powering industrial automation equipment, electronics, and consumer devices.
Description
A Switch Mode Power Supply (SMPS) is an electronic power supply that uses high-frequency switching and energy storage components (inductors, capacitors, transformers) to convert electrical power efficiently. Unlike conventional linear power supplies, SMPS offers high efficiency, compact design, and the ability to handle a wide input voltage range, making it ideal for industrial, commercial, and consumer electronic applications.
