5 Amp 13.8Vdc Power Supply with Switch Mode – Full Current Load Large Box

In large commercial installations, managing individual “plug-and-play” adapters for every camera or lock is inefficient and creates a maintenance nightmare. The Large Box Switch Mode Power Supply centralizes power distribution into a single, wall-mounted steel enclosure. Utilizing high-efficiency Switch Mode technology, these units convert AC mains into a stable DC output (typically 12V or 24V) while generating significantly less heat than older linear models.

The “Large Box” format is specifically designed to house not only the power transformer but also a Battery Backup (UPS) system. In the event of a mains failure, the Large Box Switch Mode Power Supply seamlessly switches to battery power, ensuring that security systems remain operational. This makes the Large Box Switch Mode Power Supply a critical component for life-safety systems, high-security data centers, and multi-tenant residential buildings.

Why the Large Box SMPS is the Security Professional’s Standard

The Large Box Switch Mode Power Supply provides a level of organization and protection that smaller, unboxed units cannot match.

• Integrated Multi-Channel Distribution: Features a fused distribution board, allowing the Large Box Switch Mode Power Supply to power up to 4, 8, or 16 devices independently.

• Lockable Steel Enclosure: The Large Box Switch Mode Power Supply protects against tampering and unauthorized power-downs with a keyed entry.

   

• Dedicated Battery Charging Circuit: Includes an intelligent charging module to maintain a 7Ah or 17Ah Lead-Acid battery in peak condition.

• Visual Diagnostic LEDs: Front-panel indicators on the Large Box Switch Mode Power Supply provide instant status on Mains Power, DC Output, and Battery Health.

• Individual Output Fusing: Each channel is protected by a glass fuse or PTC (Resettable) fuse, ensuring a short circuit on one door doesn’t crash the entire system.

• High Current Capacity: Available in heavy-duty ratings from 5A up to 20A to handle significant electrical loads across a facility.

• Cable Management Knockouts: Designed with pre-punched entries for 20mm conduits, keeping the Large Box Switch Mode Power Supply installation neat and compliant.

Achieving a Reliable Infrastructure Installation

When installing a Large Box Switch Mode Power Supply, location is key. It should be mounted in a ventilated area, such as a telecommunications room or a secure riser cupboard. Because these units often power critical security hardware, the Large Box Switch Mode Power Supply should be wired into a dedicated unswitched fused spur to prevent accidental disconnection.

To ensure the longevity of your system, we recommend performing a “Load Calculation” before choosing your Large Box Switch Mode Power Supply. Sum up the peak current draw of all connected maglocks, strikes, and readers, then add a 20% safety margin. Secure your building’s vital systems with a Large Box Switch Mode Power Supply—the definitive hub for professional power management.
