Traffic Signal UPS System

Runtime varies with battery configuration and load, but a properly sized 3kVA UPS with maintenance-free VRLA batteries like AlphaCell can typically provide 4 to 8 hours of backup power for traffic signal loads, depending on battery bank size and actual power draw.

A 3kVA UPS can support intersection traffic signal heads, controller cabinets, LED displays, and ITS communication equipment, typically handling combined loads up to 3000VA, including signal lamps, cabinet fans, and detection sensors.

The maximum continuous load for a 3kVA UPS is 3000VA, or roughly 2400-2700 watts depending on power factor, which should be selected with a safety margin below the UPS's rated capacity to ensure reliable traffic signal operation during outages.

Traffic signal UPS systems typically use maintenance-free Valve-Regulated Lead-Acid (VRLA) batteries, such as AlphaCell Outside Plant Batteries, which are leak-proof, ready for 100% capacity out of the box, and engineered for extended outdoor runtimes in harsh environments.

Maintenance-free VRLA batteries used in traffic signal UPS systems typically last 5 to 10 years depending on climate, discharge cycles, and maintenance practices, with outdoor-rated designs like AlphaCell built for extended service life and reduced replacement frequency.

Yes, traffic signal UPS systems and their batteries are specifically engineered for outdoor deployment, featuring leak-proof, weather-resistant designs that withstand temperature extremes and moisture while maintaining reliable backup power for intersections and ITS equipment.
