Access Control Power Supply Unit 12V5A

Product Description

A 12 V 5 A access control power supply is a dedicated power module designed to deliver stable DC power (typically ~12 V) with up to 5 amps of current to your access control components — including electric locks (maglocks, strikes), biometric/controllers, RFID readers, exit buttons and related peripherals. These units often include battery backup support, protective circuits, and timing functions essential for reliable security system operation.

Key Features & Functions

Stable Output

• Output: 12 V DC at up to 5 A (≈60 W).

• Some units allow adjustable voltage (e.g., 11.5 – 13.5 V) to suit different lock types and wiring conditions.

Battery Backup & UPS

• Most 12V 5A PSUs have a battery terminal to connect a 12 V lead–acid battery (commonly 7 Ah).

• When mains power fails, they switch to battery power seamlessly, keeping access control operational.

Protection & Safety

• Short-circuit protection: stops current flow during faults.

• Overload protection: prevents damage if too much load is applied.

• Over-voltage/Reverse polarity protection: safeguards your access devices and PSU itself.

 Lock Control

• Many units include a lock-delay timer (adjustable, e.g., 0–15 sec) so doors stay unlocked for a controlled time after access is granted.

Flexible Compatibility

Works with:
✔ Electric locks (maglocks, electric strikes)
✔ Access controllers (biometric readers, RFID panels)
✔ Exit buttons / intercom systems
✔ Alarms / auxiliary devices on the same 12 V supply.
