Keep traffic signals running with zero-interruption power protection

Prevent Signal Blackouts with Battery Backup Systems


Power outages at intersections can occur for various reasons that are largely beyond the control of city traffic and maintenance teams. However, these power losses can lead to dark traffic signals at small and large intersections, posing serious safety risks to motorists and pedestrians. Discover NexTech's Battery Backup and Power Conditioning solutions to ensure your traffic lights remain operational, even during utility power interruptions.


Clary UPS systems provide reliable, continuous power with On-Line Double Conversion technology. These systems feature zero transfer time, ensuring no interruptions in power supply. By isolating the load from utility input, rectifying AC to DC, and using an inverter to generate a true sine wave output, Clary UPS delivers clean, stable, and fully regulated voltage. Additionally, they synchronize to the input phase when online, offering seamless and reliable protection for your critical intersection equipment.

Clary Backup Power Product Line


The Clary SP1250XLE is designed to provide extended run time when configured with available lithium or 4-battery AGM systems — ideal for intersections requiring longer backup duration during extended outages. The SP1250LX offers an integrated PIM and programmable display, making it well-suited for agencies that need on-site configuration and monitoring capabilities built directly into the unit.


For modern reduced-footprint ATC traffic cabinets, the SP-1400LT provides a small form-factor online UPS optimized for tight cabinet installations. All models synchronize to the input phase when utility power is restored, offering seamless transitions that prevent signal disruption. Clary systems are engineered for all climates, making them reliable across the full range of Southern California environments from coastal to inland desert conditions.
