Its NC\/NO output selection makes it suitable for virtually any lock type used in modern access control systems, as well as RFID card readers, fingerprint machines, and exit push buttons.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use this power supply outside the United States?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The KDB05 accepts AC 100V–240V at 50\/60 Hz, covering virtually every mains voltage standard used worldwide. Simply use the appropriate plug adapter for your country's outlet format and this unit will work seamlessly.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What does the adjustable time delay do?\u003c\/h4\u003e\n\u003cp\u003eA: The time delay setting controls how long the lock remains unlocked after an access event (e.g., a card swipe or fingerprint scan). You can set it to 3, 6, or 9 seconds (with a range of 0–15 seconds) so the door re-locks automatically after the chosen interval, enhancing security without requiring manual re-locking.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does this power supply have short-circuit protection?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The KDB05 features automatic overload and short-circuit protection. If a short-circuit occurs, the unit will automatically disconnect power or trip its auto-fuse line to protect your access control system components from damage.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What types of electric locks is this access control power supply compatible with?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"The Asia-Teco KDB05 power supply is compatible with a wide range of electric locks, including electromagnetic (magnetic) locks, electric strike locks, and other 12V DC locks.
