Why Choose the KDB05?
Unreliable power is one of the most common causes of access control system failures. The Asia-Teco KDB05 addresses this with a dedicated, purpose-built power supply that isolates your locks and readers from the main controller's power bus — reducing wiring complexity, preventing voltage drops, and extending the life of your entire access control system.

Frequently Asked Questions
Q: Is this access control power supply compatible with both 110V and 220V outlets?
A: Yes. The KDB05 accepts a universal AC input range of 100V–240V, making it compatible with standard electrical outlets in North America, Europe, Asia, and most other regions worldwide.
Q: Can I use this power supply to directly power a magnetic lock?
A: Absolutely. The KDB05 is specifically designed to power electromagnetic (magnetic) locks, electric strike locks, and access controllers directly. Its NC/NO output configuration lets you match the lock type in your installation.
Q: What happens if there is a short circuit in the system?
A: The KDB05 features automatic short-circuit protection. In the event of a fault, the unit will temporarily disconnect power or trip the auto-fuse, protecting your connected devices until the issue is resolved.
Q: How do I set the lock release delay time?
A: The built-in delay control circuit allows you to adjust the lock release time anywhere between 0 and 15 seconds, giving you flexibility to match your door's access timing requirements.
