Frequently Asked Questions

Q: Does this access control power supply work with both 110V and 220V mains power?

A: Yes. The Asia-Teco TPM005B accepts a universal AC input range of 100V–240V, so it is compatible with standard mains voltage in the United States (110–120V), Europe (220–240V), and most countries worldwide — no separate voltage converter needed.

Q: What type of backup battery does this power supply support?

A: The unit includes a dedicated backup battery connection port that supports a standard 12V sealed lead-acid (SLA) battery (battery not included). When mains power is interrupted, the connected battery automatically takes over to keep your access control devices running without interruption.

Q: Can I use this power supply to directly control an electromagnetic lock without a separate access controller?

A: Yes. The TPM005B is designed to control electric locks directly. Its NC/NO output terminals allow you to wire various lock types (EM locks, electric strikes, etc.) straight to the unit, reducing the load on your access controller and simplifying your overall wiring layout.

Q: What happens if there is a short circuit in the connected load?

A: The built-in automatic protection circuit detects overload or short-circuit conditions and either temporarily disconnects the output or triggers the auto-fuse to prevent damage to both the power supply and connected devices. Once the fault is cleared, normal operation resumes.
