12VDC 5A Access Control Power Supply Switch NO/NC Time Delay
12VDC 5A Access Control Power Supply Switch NO/NC Time Delay
Access Control Power Supply Switch – AC220V Input / 12VDC Output, 5A, Adjustable Time Delay
Keep your doors, gates, and secure areas running reliably with this professional-grade Access Control Power Supply Switch (Model V30 by Asia-Teco). Designed for seamless integration into access control systems, this unit converts AC 220V mains power to a clean DC 12V output, delivering up to 5A of current — enough to drive two electromagnetic or electric strike locks simultaneously. Whether you're securing a small office or a multi-door facility, this switch gives you dependable fail-safe operation with flexible NO/NC compatibility.
Key Features
- Universal AC Input: Accepts AC 220V mains power for broad compatibility with standard electrical installations.
- Stable 12VDC Output: Delivers a consistent DC 12V supply to power access control hardware such as electric strikes, magnetic locks, and controllers.
- 5A Working Current: Sufficient capacity to simultaneously power up to 2 door locks with stable, reliable current.
- NO/NC Output Support: Compatible with both Normally Open (NO) and Normally Closed (NC) configurations for maximum wiring flexibility.
- Adjustable Time Delay: Built-in timer is user-adjustable from 1 to 15 seconds, allowing you to control how long the output remains active after a trigger event.
- Fail-Safe Security Mode: Designed to default to a safe state in the event of a power interruption, helping protect your premises.
- Durable ABS Shell: Robust ABS plastic housing stands up to everyday use in commercial and light-industrial environments.

Frequently Asked Questions
Q: What type of locks can I connect to this access control power supply switch?
A: This power supply switch outputs DC 12V at up to 5A, making it compatible with most 12V electromagnetic locks, electric strike locks, and electric bolt locks. The 5A capacity is sufficient to power up to two standard door locks simultaneously, making it a great fit for small multi-door access control setups.
Q: What is the difference between NO (Normally Open) and NC (Normally Closed) output modes?
A: In Normally Open (NO) mode, the circuit is open (unlocked) by default and closes (locks) when power is applied or a signal is triggered. In Normally Closed (NC) mode, the circuit is closed (locked) by default and opens when triggered. This unit supports both configurations, giving you flexibility to match your specific lock type and security requirements.
Q: How does the adjustable time delay work on this unit?
A: The built-in time delay allows you to set how long the output remains active after a trigger event — anywhere from 1 to 15 seconds. This is useful for applications like automatic door closing, where you want the lock to re-engage after a set period following an authorized entry without requiring a manual reset.
Q: Is this power supply switch suitable for 110V AC systems?
A: No. This model is designed specifically for AC 220V input. If you are in a region with 110V AC mains power, please ensure you use an appropriate step-up transformer or source a unit rated for your local voltage before installation.
Q: What does "Fail Safe" security mode mean for this device?
A: Fail Safe means that in the event of a power failure or disruption, the device defaults to an unlocked (open) state. This is important for emergency egress — ensuring people can exit a building freely if power is lost. This mode is commonly used with magnetic locks in office and commercial environments.
