Mining Encapsulated Intrinsically Safe Power Supply

The KDW127/12B Mining Encapsulated Intrinsically Safe Power Supply is a rugged, certified DC power source engineered for reliable operation in underground coal mines and other explosive atmospheres. Designed with encapsulation (Ex mb) and intrinsically safe (Ex ib) protection, this power supply converts an AC127V (75%–110% range) input into a stable DC12V output with a rated current of 1.5A, delivering up to 100VA input apparent power. Its advanced integrated circuit architecture ensures high current stability, with output voltage deviation kept within ±5%, source effect and load effect both below 5%, and a peak‑to‑peak periodic and random deviation of ≤250mV, guaranteeing clean power for sensitive electronic equipment. Safety is paramount: the unit features comprehensive overcurrent protection (trip value ≤1600mA) and short‑circuit protection (short‑circuit current ≤20mA), preventing damage to connected devices.
