Description
Access Control Power Supply Unit (PSU) 12V 3A
Stable Power Delivery: Provides a clean, regulated 12V DC output, with 3A instantaneous (peak) current to support electromagnetic locks, strikes, and exit buttons.
Adjustable Output Voltage: Allows fine-tuning (usually 12V to 15V) to compensate for voltage drop over longer cable runs.
Built-In Time Delay: Supports a user-adjustable relay timer (typically 0 to 15 seconds).
Fail-Safe/Fail-Secure Modes: Features NC (Normally Closed) and NO (Normally Open) outputs to control different lock types.
- Electric drop bolts & electromagnetic locks.
- Biometric readers and RFID card controllers.
- Access keypads and exit buttons.
- Doorbell / Intercom systems.
- Current Threshold: Rule of thumb is to calculate the total current draw of all devices (locks + readers) and keep it under 80% of the power supply’s capacity.
- Battery Backup: For uninterrupted security during mains power outages, ensure your setup utilizes a compatible 12V backup battery.
- Voltage Drop: Keep cable runs short or use heavier gauge wires to prevent voltage drop over distance.
High and low, three-way switch, over-current, over-voltage and short circuit protection.12VDC 3A access control power supply is characterized by its anti-interference ability, stability and reliability. Power application range applied to a variety of construction intercoms, and access to a variety of import and export controls, especially applicable to a variety of electric lock motors. It can reduce the load of the access controller, and save wiring to reduce hidden trouble.
