The Asia-Teco LK1205 accepts a wide AC input range of 100–240V, making it compatible with power outlets in the US, Europe, Asia, and most other regions worldwide.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What backup battery do I need for this power supply?\u003c\/h4\u003e\n\u003cp\u003eA: This unit supports a 12V 7Ah battery with a DC voltage of 12.5–14V. When connected, the backup battery can keep your access control system running for approximately 3–5 hours during a power outage. The battery is sold separately.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What happens if there is a short circuit or overload?\u003c\/h4\u003e\n\u003cp\u003eA: The LK1205 is designed with built-in protection. On a short circuit, the unit immediately shuts down output and signals the fault with a flashing red LED. On overload, it gradually reduces output. Once the fault condition is cleared, the unit automatically recovers — no manual reset is required.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this power supply compatible with RFID card readers and electric locks?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. This power supply is specifically designed for access control systems, including RFID card readers, electromagnetic locks (maglocks), electric strike locks, and door controllers that operate at DC 12V.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is Fail Safe mode?\u003c\/h4\u003e\n\u003cp\u003eA: Fail Safe means that in the event of a power failure or fault, the connected locks or devices will default to an unlocked (open) state, ensuring people can safely exit a building or secured area. This is a common requirement in fire-safety and emergency egress scenarios.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"Does this access control power supply work with international voltages?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"Yes.
