Securitron BR4 4 Amp Bridge Rectifier Access Control

Product Description

The SECURITRON BR4 is a 4 amp bridge rectifier designed for use in access control and electric locking system installations. A bridge rectifier converts alternating current (AC) to direct current (DC), providing the stable power supply that electromagnetic locks and access control hardware require to operate reliably. At 4 amps, the BR4 handles the load demands typical of single- and multi-door locking systems. Electricians and low-voltage access control technicians are the primary installers of this component.

The BR4 is used in commercial and residential access control applications where AC power must be converted to DC for electric locking devices. It fits into panel enclosures and power supply assemblies, making it a practical component for new installations and service replacements alike. Its compact footprint — 5.3 inches long, 3 inches wide, and 1.2 inches tall — allows integration into tight enclosure spaces without modification.

Key Features

• 4 amp output rating supports single- and multi-door electric locking loads
• Converts AC input to DC output for stable electromagnetic lock operation
• Compact form factor: 5.3 x 3 x 1.2 inches for installation in standard panel enclosures
• Lightweight at 0.1 pounds, minimizing added load on enclosure mounting hardware
• Sold individually for targeted component replacement or system expansion

Compatibility

Designed as an OEM-style replacement or add-on component for access control and electric locking system power supply assemblies requiring bridge rectifier functionality.

Installation Notes

Installation should be performed by a licensed electrician or certified low-voltage access control technician. Disconnect and de-energize all power sources before handling or replacing the rectifier. Follow applicable NEC guidelines for low-voltage access control wiring. Verify that the rectifier's amp rating meets or exceeds the total locking device load before energizing the circuit.
