The Design of Mine-used Intrinsically Safe Power

This article introduces a practical high current output mine-used intrinsically safe power, gives the working principle, system composition and working process of the power, and every part of system designs is discussed in detail. Its output voltage is 18 V and the current is 1.2 A, and this intrinsically safe power could meet the high current power supply requirements of automation system in the coal mine working face.
