The KDW1140/24B(A) explosion-proof and intrinsically safe multi-channel DC regulated power supply for mines is suitable for coal mines where there may be gas and coal dust explosions. It provides four intrinsically safe power outputs for intrinsically safe equipment of mines, and supports 4h continuous operation in case of power failure. The battery is subject to overcharge and current limiting protection. In addition, the battery can be disconnected via the knob switch, to ensure the safe use. In addition, the power supply status, the status of each intrinsically safe output power supply, and the working status of the battery are displayed in real time on the LCD screen. The power supply supports online monitoring and remote ON/OFF control. It is able to report the strong current input, output voltage/current and battery status to the system in real time. This is conducive to on-site real-time observation of equipment working status.
