With a suitable battery connected, the system can continue operating for approximately 3–5 hours during a power outage. Note: the backup battery is not included.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the difference between the KD1205 and KD1203 models?\u003c\/h4\u003e\n\u003cp\u003eA: The KD1205 provides a DC 12V 5A output, while the KD1203 provides a DC 12V 3A output. Choose the 5A model for systems with higher current demands (e.g., multiple locks or larger electromagnetic locks) and the 3A model for lighter-duty or single-lock installations.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Is this power supply compatible with RFID card access control systems?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. This unit is specifically engineered to power RFID card readers, electromagnetic locks, electric strikes, and associated access control accessories that require a stable 12V DC supply.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What happens if there is a short circuit or overload on the output?\u003c\/h4\u003e\n\u003cp\u003eA: The power supply features intelligent fault protection. On an overload, output is gradually reduced to protect the connected equipment. On a short circuit, output shuts down immediately and a red LED flashes to indicate the fault. Once the fault condition is cleared, the unit automatically recovers — no manual reset required.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What backup battery does this access control power supply support?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This power supply is compatible with 12V 7Ah sealed lead-acid batteries with a charging voltage of DC 12.5–14V.
