Frequently Asked Questions
Q: What types of electric locks is this DC 12V access control power supply compatible with?
A: This power supply is compatible with a wide range of 12V electric locks and access control hardware, including electromagnetic (EM) locks, electric strike locks, RFID card readers, fingerprint access controllers, and exit push buttons. Its configurable NC/NO output makes it adaptable to most common lock types on the market.
Q: How does the remote control unlock feature work?
A: The included 433.92 MHz fixed-code remote communicates wirelessly with the power supply unit. When triggered, it sends an unlock signal that directly controls the connected electric lock — no need to reach a keypad or reader. The effective range is up to 20 meters in open conditions, making it ideal for garages, gates, and office entry doors.
Q: What happens if there is a power outage or short circuit?
A: This unit features Fail Secure mode, which means the connected electric lock remains locked if power is lost — ensuring your access point stays secure during an outage. In the event of a short circuit, the automatic protection circuit will temporarily disconnect the output or trigger the auto-fuse to protect your connected equipment.
Q: Can this power supply be used internationally with different voltage standards?
A: Yes. The unit accepts a wide AC input range of 110V to 240V at 50/60 Hz, making it suitable for use in North America, Europe, Asia, and most other regions without requiring a voltage converter.
