AB0302A-277 Unity Architectural Ballast Driver

(What discontinued products are comparable to this product?)

The Lightronics AB0302A-277V is an A/C dimmed, switched HOT / dimmed HOT ballast driver designed for DMX-512 operation and for integration into Lightronics Unity Architectural Lighting Control systems. Powered by 120VAC device power, it controls 277V lighting loads, making it suitable for higher-voltage applications commonly found in commercial lighting systems. Installed between the control system and lighting loads, it provides centralized control through Unity Architectural remote stations, DMX-512 control input, or contact closures.

Key Features
 • 3 control channels, 2,400W per channel (7,200W total)
 • Controls 277V lighting loads with 120VAC device power
 • A/C dimmed output with switched HOT feed capability
 • Compatible with Unity Architectural Lighting Control systems
 • Supports Unity Architectural remote station control
 • Supports DMX-512 control input
 • Programmable for up to 64 preset lighting scenes
 • Softpatch capability for flexible channel assignment
 • Contact closure inputs for external control integration
 • Nonvolatile memory retains scenes when powered down

Users can quickly recall preset lighting scenes while maintaining simple control through Unity Architectural wall stations or DMX-512 input. This allows consistent, repeatable lighting operation in environments where ease of use is essential. In addition, the ability to control 277V loads while operating from a 120VAC power source makes the unit well suited for installations requiring higher-voltage lighting circuits.

Integration into existing lighting systems is straightforward. The AB0302A-277V supports Unity Architectural remote stations for simple preset scene control, while DMX-512 allows connection to broader lighting control systems. Softpatching simplifies system setup and addressing, and contact closure inputs expand control options for automated or external triggering. As a result, the unit works well in both new installations and retrofit applications where 277V lighting control is required.

Designed for dependable, long-term operation, the AB0302A-277V delivers consistent performance in architectural lighting environments. Its durable construction and ability to manage higher-voltage loads make it a practical solution for facilities requiring reliable, flexible lighting control.
