DC 12V 5A Access Control Power Supply – Video Intercom Adapter
Asia-Teco DC 12V Access Control Power Supply Switch – 5A Output
Power your access control system with confidence. The Asia-Teco DC 12V Access Control Power Supply Switch delivers a stable 12V DC output with up to 5A momentary current (3.5A continuous), making it the ideal dedicated power source for electric locks, video intercom systems, door bells, exit push buttons, and access controllers. Featuring a wide AC input range of 110V–240V at 50–60Hz, this CE-certified, metal-housed unit is built for reliability and long service life.
Key Features
- Durable Metal Construction: High-quality metal enclosure ensures long-lasting, dependable performance in demanding environments.
- Direct Electric Lock Control: Drives electric locks directly without overloading your access controller, reducing wiring complexity and extending the life of your system.
- NC / NO Output Modes: Supports both Normally Closed (NC) and Normally Open (NO) configurations to work with virtually any type of electric lock or access device.
- Adjustable Time Delay: Built-in delay control circuit allows lock release time to be set from 0–10 seconds or 0–15 seconds (model dependent), giving you flexible control over door timing.
- Fail-Safe Security Mode: Designed with a fail-safe mode for enhanced security — the lock defaults to a safe state in the event of a power interruption.
- Automatic Protection Function: Integrated overload and short-circuit protection helps safeguard connected equipment.
- Wide Universal Input: Accepts AC 110V–240V input at 50–60Hz, suitable for use in North America, Europe, and most regions worldwide.

Why Choose a Dedicated Access Control Power Supply?
Routing power for electric locks directly through an access controller can strain the controller and cause premature wear or system instability. A dedicated power supply unit like this one isolates the high-current lock load, ensuring your access controller operates within its rated limits. For more information on best practices in access control and building security systems, refer to guidance from the U.S. Consumer Product Safety Commission (CPSC) regarding electrical safety standards for consumer and commercial devices.
Frequently Asked Questions
Q: What types of electric locks is this DC 12V access control power supply compatible with?
A: This power supply is compatible with a wide range of electric locks and access control devices that operate on DC 12V, including Normally Open (NO) and Normally Closed (NC) electric locks, magnetic locks (maglocks), access controllers, exit push buttons, door bells, and video intercom systems.
Q: Can I use this power supply with both 110V and 240V mains power?
A: Yes. The unit accepts a universal AC input of 110V–240V at 50–60Hz, making it suitable for installation in North America, Europe, Asia, and most other regions around the world without the need for a separate voltage converter.
Q: How does the adjustable time delay function work?
A: The built-in delay control circuit lets you set how long the lock stays released after an access event (such as a button press or card read). Depending on the model (KDB05 or KDB08), the delay is adjustable from 0–10 seconds or 0–15 seconds, giving you precise control over door release timing for your specific application.
Q: What is "Fail Safe" security mode?
A: In Fail Safe mode, the electric lock defaults to its unlocked (open) state in the event of a power failure. This is commonly used in life-safety applications where doors must remain passable during an emergency, such as fire egress routes. In contrast, "Fail Secure" locks remain locked when power is lost. Always consult your local building codes and fire safety regulations when selecting a security mode.
Q: Is this power supply protected against overloads or short circuits?
A: Yes. The unit features an automatic protection function that guards against overload and short-circuit conditions, helping to protect both the power supply and connected access control equipment from damage.
