Frequently Asked Questions
Q: What types of locks is this door access control power supply compatible with?
A: This DC 12V 5A power supply is compatible with a wide range of electric locks, including electric strike locks, magnetic locks (maglocks), and other 12V DC locking devices. It supports both NO (Normally Open) and NC (Normally Closed) lock configurations, making it versatile for most access control installations.
Q: Can I use this power supply with a battery backup for uninterrupted operation?
A: Yes. This unit is designed to support a battery backup. It includes battery anti-polarity protection so that if a battery is accidentally connected in reverse, only the fuse activates and the main unit remains undamaged. It also features automatic overdischarge protection, disconnecting the battery when voltage falls below 9.5V to preserve battery life.
Q: How do I set the delay time on this access control power supply?
A: The delay time is fully adjustable from 0 to 15 seconds via the built-in adjustable design on the unit. You can fine-tune this setting to control how long the lock stays released after an access event, providing flexibility for different door types and security requirements.
Q: Is this power supply safe to use with my existing access controller?
A: Yes. This power supply is specifically designed to reduce the load on your access controller by providing dedicated power directly to the locking mechanism. It features overcurrent, overvoltage, and short-circuit protection, and its anti-interference design ensures stable, reliable operation alongside your existing access control hardware.
