Frequently Asked Questions
Q: What is the difference between the 12V 3A and 12V 5A access control power supply?
A: The 12V 3A model is sufficient for powering a single electric lock along with its access controller. The 12V 5A model provides greater current capacity and is recommended when two locks are connected to the same power supply, ensuring more stable and reliable operation.
Q: Is this DC 12V switch power supply compatible with both RFID and fingerprint access control systems?
A: Yes. This power supply is designed to work with a wide range of access control devices including RFID/IC card readers, fingerprint controllers, electromagnetic locks, electric strike locks, and exit push buttons — making it a versatile solution for most door access control installations.
Q: Does this power supply work with AC voltages outside the US (110V)?
A: Absolutely. The 3A model accepts AC input from 110V to 260V, and the 5A model accepts 90V to 260V, making both units compatible with global electrical standards including 110V (North America) and 220–240V (Europe, Asia, Australia).
Q: What happens if there is a short circuit in the connected lock or controller?
A: This power supply includes an automatic protection circuit. In the event of a short circuit or overload, the unit will temporarily disconnect output or the auto-fuse will trip, protecting both the power supply and any connected devices from damage.
