Frequently Asked Questions
Q: What types of electric locks is this door access control power supply compatible with?
A: This DC12V 5A power supply is compatible with a wide variety of electric locks, including magnetic locks, electric strikes, and electric bolts that operate at DC 12V. It supports both Normally Open (NO) and Normally Closed (NC) lock configurations, making it highly versatile for most access control installations.
Q: Does this power supply support a backup battery connection?
A: Yes. This access control power supply includes a backup battery connection interface with anti-polarity protection and overdischarge protection. If the battery voltage drops below 9.5V, the unit automatically disconnects it to prevent damage — and if the battery is connected in reverse, only the fuse is affected, keeping the main unit safe.
Q: What does the adjustable delay timer do?
A: The adjustable delay timer (0–15 seconds) controls how long the electric lock remains unlocked after an access event is triggered. This allows you to set the exact door-open duration that suits your security requirements — from a brief 1-second release to a full 15-second window.
Q: Is this power supply suitable for both residential and commercial access control systems?
A: Absolutely. With a universal AC 110V–240V input, 5A output current, and 50W high-power transformer, this unit is well-suited for both residential building intercom systems and larger commercial access control deployments with multiple electric locks or entry points.
