Frequently Asked Questions
Q: What types of electric locks is this DC 12V 4A access control power supply compatible with?
A: This power supply is compatible with a wide range of electric locks, including electromagnetic (EM) locks, electric strikes, and electric bolt locks. 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.
Q: Can I use this power supply with both 110V and 240V mains power?
A: 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.
Q: How do I set the lock release delay time?
A: 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.
Q: What happens if there is a short circuit?
A: 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.
