Mine-use sealed and intrinsically safe DC regulated power supply is mainly used in mines with gas and coal dust explosion hazards. The power supply has 1 intrinsically safe power output function; it has overcurrent short-circuit protection function, and can automatically resume normal operation after the fault is removed. It can be used as a power supply, and can also be used as a general intrinsically safe uninterruptible power supply in the video system. Explosion-proof type: mine intrinsically safe type, marked as "Ex [ib] mb I Mb".
