## Description

This industrial-grade 50W high-power step-down module offers a voltage input range of 9-18V and a maximum output of 5V/10A. It has the characteristics of high isolation withstand voltage of 1500V DC or 800V AC, low radiation interference, ripple noise, etc. With short-circuit protection and input under-voltage protection mechanisms, the converter can be widely used in portable power supply systems on the chassis, railway locomotives, new energy, communications, electric power, industrial control, occasions where input and output are isolated and other industries.
