Hager 2908 — 12/24 VDC 1-Amp Regulated Power Supply for Commercial Door Hardware

The Hager 2908 is a UL-listed, regulated 1-amp power supply designed to drive electric door hardware from a single, dependable source. Accepting standard 120 VAC line input, it delivers a clean, field-selectable 12 VDC or 24 VDC output — making one part number suitable for the vast majority of commercial access-control installations. Typical loads include electric strikes, magnetic locks (maglocks), electrified power transfers (EPT), and low-energy door operators.

Built for the demands of commercial openings, the 2908 provides filtered, regulated DC output with over-current protection in a compact enclosure suited for header, above-ceiling J-box, or dedicated electrical cabinet mounting. An optional battery backup accessory — the Hager 2-679-0661 (5 Ah sealed lead-acid) — extends standby operation through utility outages.

Key Features & Benefits

• Field-Selectable 12/24 VDC Output: Jumper-selectable voltage covers fail-safe and fail-secure locking devices from a single part number, reducing stocking complexity.
• 1 Amp Continuous Regulated Output: Filtered, regulated DC rated for continuous duty — sufficient headroom for multiple low-draw devices or a single higher-demand load.
• 120 VAC Standard Line Input: Connects directly to any commercial branch circuit; no special transformer required.
• Battery-Backup Ready: Compatible with the Hager 2-679-0661 5-amp-hour battery backup for uninterrupted operation during power outages.
• Over-Current Protection: Built-in protection guards both the supply and connected hardware against faults and current surges.
• UL Listed: Meets UL listing requirements for use in commercial access-control systems.
• Compact Enclosure: Space-saving footprint simplifies installation in headers, j-boxes, or electrical cabinets.

Typical Applications

• Powering electric strikes in office, healthcare, and educational facilities
• Driving magnetic locks (maglocks) on single-door access-control openings
• Supplying electrified power transfers and low-energy operators
• Providing a dedicated, clean DC source for access-control readers and ancillary devices sensitive to power noise
• Schools, hospitals, government buildings, and commercial office retrofit projects
