Mining Flameproof Intrinsically Safe Power Supply

The KDW660/24B is a certified mining flameproof intrinsically safe DC regulated power supply designed for explosive gas environments with coal dust and methane. It converts AC660V (input apparent power ≤200VA) into five independent intrinsically safe DC outputs, providing stable and reliable power to various underground equipment. The unit features a robust Q235 steel enclosure, Ex mb [ib mb] I Mb certification (MAA230287), and operates within 0°C to +40°C and 95% humidity. An integrated backup battery system using 20 series‑connected NI‑MH cells (1.2V/13000mAh each) ensures uninterrupted operation for at least two hours at rated current, with a seamless switching time of ≤0.5s. The built‑in intrinsically safe communication port supports TCP/IP Ethernet at 10/100Mbps, enabling remote monitoring and control over distances up to 50 meters using MHYVRP cable. This power supply is the ideal energy source for powering Mine intrinsically safe cameras, ensuring continuous video feeds even dur…
