Frequently Asked Questions
What is an access control power supply?
An access control power supply converts standard wall AC power into the regulated DC voltage that electrified locks, electric strikes, and other electronic door hardware require. It is the backbone of any access-controlled door system.
What voltage do I need for my electrified lock?
Most commercial electrified locks and strikes operate on either 12V DC or 24V DC. Always check the manufacturer's specifications for your specific lock or strike before selecting a power supply. Some units offer both outputs.
Do access control power supplies include battery backup?
Many commercial power supplies include a built-in battery backup or a battery backup input, ensuring your locks continue to operate during a power outage. This is especially important for fail-safe locks and ADA-compliant exit doors.
How many outputs do I need?
That depends on how many doors you are controlling. Single-door setups typically use a single-output supply, while multi-door systems require multi-channel or multi-zone units. Each output can typically power one lock or strike.
Are access control power supplies UL listed?
Yes. For commercial installations, always select a UL-listed power supply. This ensures the unit meets safety standards and will satisfy code inspection requirements.
