Frequently Asked Questions
Q: What voltage does this mini electric cabinet lock require?
A: This electric cabinet lock operates on DC 12V at 2A. Make sure your power supply matches these parameters for safe and reliable operation. It is not directly compatible with 5V-only systems without a step-up converter.
Q: How does the lock's work mode function?
A: This lock uses an independent (fail-secure) work mode. When power is off and the door is closed, the lock engages automatically. When power is applied, the lock releases (unlocks). This makes it ideal for automated locker systems and vending machines where security during power loss is essential.
Q: Can this electric lock be installed in any orientation?
A: Yes. The compact design has no left, right, front, or reverse side limitation, so it can be mounted in virtually any orientation to suit your cabinet or locker configuration. A mechanical emergency unlock feature is also included for manual override.
Q: What types of cabinets or enclosures is this lock compatible with?
A: This mini electric lock is designed for lightweight cabinet doors weighing between 0.5 and 4 kg. It is ideal for delivery lockers, refrigerated cabinets, mailboxes, self-service lockers, book counters, changing-room cabinets, and vending machines.
Q: What does the feedback signal line do?
A: The feedback signal line is a short-circuit signal switch built into the lock. It is open (disconnected) when the lock is in the unlocked state, and closed (connected) when the lock is engaged. This allows external control systems or microcontrollers to monitor the lock status in real time.
