DC 12V Access Control Power Supply 3.5A 5A – Wide AC Input
DC 12V Access Control Switch Power Supply – 3.5A & 5A Options
Power your door access control system with confidence using this robust DC 12V switching power supply from Asia-Teco. Available in 12V 3.5A and 12V 5A versions, this unit is engineered with high-quality electronic components and advanced switching technology to deliver stable, reliable output across a wide range of access control applications — including electric locks, RFID/IC card readers, access controllers, and exit push buttons.
Which Output Should You Choose?
- 12V 3.5A — Ideal for installations powering a single electric lock from the supply.
- 12V 5A — Recommended for installations powering two electric locks simultaneously, offering greater headroom and a more stable output.
Key Features
- Wide AC Input Range: Accepts AC 90V–260V (12V 3.5A model) or AC 90V–260V (12V 5A model), making it compatible worldwide.
- Regulated DC Output: Delivers a clean, stabilized DC 12V output at 3.5A or 5A.
- Direct Electric Lock Control: Controls electric locks directly without requiring additional relay boards.
- Reduced Controller Load: Offloads power demand from your access controller, simplifying wiring and improving system reliability.
- NC / NO Output Selection: Configurable Normally Closed or Normally Open outputs to suit various electric lock types.
- Adjustable Lock Release Delay: Built-in delay control circuit allows lock open time to be set between 0–15 seconds.
- Automatic Protection: Features short-circuit protection; in the event of a power fault, the supply safely disconnects or the auto-fuse trips to protect connected devices.
- Fail-Safe with Signal Mode: Operates in Fail Safe with Signal mode for added installation flexibility.
- Anti-Interference Design: Advanced internal circuitry minimizes electromagnetic interference for consistent performance.

Frequently Asked Questions
Q: What is the difference between the 12V 3.5A and 12V 5A access control power supply?
A: The 12V 3.5A version is sufficient for powering a single electric lock from the supply. The 12V 5A version provides a higher current output and is the recommended choice when powering two electric locks simultaneously, ensuring a more stable and reliable operation.
Q: What types of electric locks and devices are compatible with this power supply?
A: This DC 12V switch power supply is compatible with electromagnetic (E/M) locks, electric strike locks, access controllers, exit push buttons, and RFID/IC card readers — making it a versatile power solution for most door access control systems.
Q: Does this access control power supply work with both 110V and 220V mains power?
A: Yes. The unit accepts a wide AC input range of 90V to 260V, making it compatible with standard mains voltages used in both North America (110V/120V) and international markets (220V/240V) without any manual voltage switching.
Q: What does the Fail Safe with Signal security mode mean?
A: In Fail Safe mode, the electric lock is released (door unlocks) if power is cut, ensuring people can exit safely during a power outage. The "with Signal" designation means the unit also provides a signal output that can be monitored by the access controller to indicate the power status.
Q: Does the power supply include short-circuit protection?
A: Yes. This unit features automatic protection circuitry. If a short circuit occurs, the power supply will temporarily disconnect output or the auto-fuse will trip, protecting connected devices such as locks and access controllers from damage.
