The KDW660/24B(A) intrinsically safe and explosion-proof DC power supply for mining (hereinafter referred to as the power supply) is mainly used for safe power supply to shearer controllers and other related equipment. It has functions such as voltage regulation, overload, short circuit, and overvoltage protection, and it can replace a battery pack in a mining environment.

• The power supply has functions such as voltage regulation, overload, short circuit, and overvoltage protection, and automatically recovers after the fault is eliminated.
• It can operate safely and reliably under harsh environmental conditions such as humidity and dust.
• Equipped with an intelligent monitoring system to monitor voltage, current, and other operating parameters in real-time.
• It features multiple input voltage options and wide output voltage regulation range, meeting different needs.
• The communication interface is compatible with the RS485 protocol, supporting data transmission and remote monitoring.
