DC 12V 5A 50W Door Access Control Switch Power Supply

DC 12V 5A 50W Door Access Control Switch Power Supply — AC 110–240V

Power your electronic access control systems with confidence. The Asia-Teco TA208CK-D is a robust 50W switching power supply designed specifically for door access control installations, building intercoms, electric lock drivers, and entry/exit management systems. With wide-range AC input (110–240V) and stable DC 12V / 5A output, it's built for reliable, round-the-clock operation in commercial and residential security setups.

Key Features

• Wide-Input Compatibility: Accepts AC 110V–240V input, making it suitable for use worldwide without additional adapters.
• Stable 12V / 5A Output: Delivers clean DC 12V at up to 5A (50W) to power electric locks, access controllers, intercoms, and more.
• Triple Control Methods: Supports high, low, and switch control modes for versatile integration with a wide range of access control hardware.
• Built-In Protections: Overcurrent, overvoltage, and short-circuit protection circuits safeguard both the power supply and connected devices.
• Battery Backup Ready: Includes battery anti-reverse polarity protection (only the fuse is affected if the battery is connected backwards) and automatic overdischarge cut-off when battery voltage drops below 9.5V.
• Adjustable Delay Timer: New upgrade design allows output delay adjustment from 0 to 15 seconds — ideal for timed electric lock releases.
• Remote Control Module Slot: Integrated lock slot for remote control modules within the access control system.
• Reduces Wiring Complexity: Offloads power demands from the access controller itself, simplifying wiring and reducing potential issues.
• Durable Metal Enclosure: Solid metal construction for heat dissipation and long-term durability in installed environments.

Frequently Asked Questions

Q: What devices can this DC 12V 5A access control power supply power?

A: This power supply is compatible with a wide range of 12V DC security and access control devices, including electric door locks (magnetic locks, electric strikes), access control panels, building intercoms, card readers, and other entry/exit management hardware that requires up to 5A of current at 12V.

Q: Does the TA208CK-D support battery backup?

A: Yes. The unit is designed to work with a backup battery. It features anti-reverse polarity protection (only the fuse blows if the battery is connected backwards, protecting the unit) and an automatic overdischarge protection that disconnects the battery when voltage drops below 9.5V to preserve battery life.

Q: What does the adjustable delay timer (0–15 seconds) do?

A: The built-in adjustable delay timer controls how long the output remains active after a trigger signal — for example, how long an electric door lock stays unlocked after an access event. You can set this anywhere from 0 to 15 seconds depending on your application requirements.

Q: Is this power supply compatible with both 110V and 240V electrical systems?

A: Yes. The TA208CK-D accepts a wide AC input range of 110V to 240V, making it suitable for use in North America, Europe, and most other regions without the need for a separate voltage converter.

Q: What protections are built into this power supply?

A: The unit includes overcurrent protection, overvoltage protection, short-circuit protection, battery reverse-polarity protection, and battery overdischarge protection — providing comprehensive safeguarding for both the power supply itself and all connected equipment.
