The Lightronics AB0302D is a D/C dimmed, 0–10V control interface ballast driver designed for DMX-512 operation and for integration into Lightronics Unity Architectural Lighting Control systems. Installed between the control system and lighting loads, it provides centralized control of dimmable fixtures through Unity Architectural remote stations, DMX-512 control input, or contact closures. Utilizing a 120VAC hot feed with a Class II 0–10VDC analog control signal, it supports low-voltage dimming control of LED and fluorescent lighting systems.

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 0–10VDC dimming capability supports smooth, low-voltage control of modern LED and fluorescent lighting systems.

Integration into existing lighting systems is straightforward. The AB0302D 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. The unit can also operate as a relay-style device when only switched HOT control is required, providing added flexibility in mixed system applications.

Designed for dependable, long-term operation, the AB0302D delivers consistent performance in architectural lighting environments. Its durable construction and low-voltage dimming capability make it a practical solution for facilities requiring energy-efficient control, smooth dimming performance, and reliable system integration.
