AB0302A Unity Architectural Ballast Driver

(What discontinued products are comparable to this product?)

The Lightronics AB0302A 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. Installed between the control system and lighting load, it provides centralized control of dimmable fixtures and switched circuits through wall stations, DMX-512 control input, or contact closures. This configuration supports reliable operation of fluorescent and LED lighting systems, as well as other 120V devices requiring switched HOT feed control.

Key Features
 • 3 control channels, 2,400W per channel (7,200W total)
 • 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 combination of dimmed A/C output and switched HOT feed provides flexibility to control a wide range of lighting loads, including dimmable fluorescent fixtures, LED drivers, and other devices requiring switched HOT control.

Integration into existing lighting systems is straightforward. The AB0302A 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 updated control is required without replacing existing infrastructure.

Designed for dependable, long-term operation, the AB0302A delivers consistent performance in architectural lighting environments. Its durable construction and stable control capabilities support reliable daily use, making it a practical solution for facilities that require simple operation, energy-efficient lighting control, and long-term system stability.
