KDW220/18B(B) encapsulated and intrinsically safe DC regulated power supply for mine
The KDW220/18B(B) encapsulated and intrinsically safe DC regulated power supply for mines adopts a high-performance integrated circuit and outputs the stable DC voltage. The power output is protected from overvoltage, overcurrent, short circuit, etc. In addition, indicators are used to indicate the real-time input, output and battery status. 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. The backup battery is a lithium iron phosphate battery featuring small size and large capacity, which can continue to output the voltage for more than 4h after AC power cutoff. The power supply can be used in coal mines to supply stable and uninterrupted power to monitoring, communication and other equipment.
