QHL750300S24

DC-DC converters are a class of power supply that steps up, steps down, or inverts electric power. They are a versatile, cost-effective solution for different electrical power system needs. One such converter is the QHL750300S24, a buck converter that offers 24V input and outputs a regulated 12V with 12A maximum current.The QHL750300S24 is an isolated DC-DC converter, meaning that it uses a transformer to separate input and output circuits to prevent current from flowing between them. It has a wide input voltage range of 18 to 36V, allowing it to accommodate most DC systems like motor controllers or renewable energy systems. Additionally, it offers active power factor correction and soft start features to provide a smooth start-up and reduce the inrush current.The QHL750300S24 is designed and manufactured to be highly efficient, with 95% efficiency at rated output power. It also features over-voltage, over-current, short-circuit, and over temperature protection, allowing it to reliably operate in harsh environments. Moreover, it is RoHS-certified and compliant with EMC standards, making it safe and easily integrated into existing electrical systems.The working principle of the QHL750300S24 is simple. It has a buck switch-mode topology, meaning that it uses a switch to regulate the voltage in an inductor. When the switch is closed, the inductor absorbs energy from the input power source and stores it in its magnetic field. When the switch is opened, the energy stored in the inductor is released and stepped down to the desired voltage.Overall, the QHL750300S24 is a cost-effective, reliable, and efficient DC-DC converter designed to provide a regulated 12V output. It features versatile input voltage, active power factor correction, overload and short-circuit protection, and RoHS-compliancy. Its simple buck switch-mode topology makes it easy to operate and maintain, and its high efficiency ensures minimal wastage of energy. In conclusion, the QHL750300S24 is an ideal choice for applications requiring 24V input and 12V output.
