It also works with RFID card readers, fingerprint access controllers, and exit push buttons — making it a versatile choice for most 12V access control setups.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I use this power supply with both 110V and 240V mains power?\u003c\/h4\u003e\n\u003cp\u003eA: Yes. The Asia-Teco CU-P9 accepts a wide AC input range of 90V to 260V, so it operates on both 110V (North American standard) and 220–240V (European\/international standard) mains supplies without any manual voltage switching.\u003c\/p\u003e\n\n\u003ch4\u003eQ: How do I set the lock release delay time?\u003c\/h4\u003e\n\u003cp\u003eA: The built-in delay control circuit lets you adjust the lock release (unlock) duration from 0 to 15 seconds. This is typically done via an onboard trim potentiometer or jumper setting — refer to the included documentation for exact adjustment instructions.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What happens if there is a short circuit?\u003c\/h4\u003e\n\u003cp\u003eA: The CU-P9 features automatic short-circuit protection. If a fault occurs, the unit will either temporarily disconnect its output or trip its built-in auto-fuse, protecting your locks and access controllers from damage until the fault is cleared.\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 DC 12V 4A access control power supply compatible with?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This power supply is compatible with a wide range of electric locks, including electromagnetic (EM) locks, electric strikes, and electric bolt locks.
