Stable Power for Continuous Signal Operation

Power supplies are essential for delivering consistent, regulated electricity to all traffic cabinet components. They convert incoming voltage to the precise levels required for controllers, detectors, and communication equipment—ensuring smooth, uninterrupted performance.

Protecting Equipment from Power Fluctuations

Modern traffic power supplies are built with surge protection, overload safeguards, and failover features to defend critical systems against voltage spikes and outages. This protection extends the life of cabinet components and reduces the risk of costly downtime or repairs.

Designed for Compatibility and Efficiency

Traffic cabinet power supplies are engineered for compatibility with NEMA and ATC standards, allowing easy integration into both new and retrofit installations. Their energy-efficient designs minimize waste and heat generation, supporting long-term reliability and sustainability.

What Our Clients Say About Working with ATS Traffic

Read authentic reviews from businesses and organizations
we’ve served throughout Canada.

Very efficient and nice people working there.

Cory Farley

Google Review, Regina

We rent Signage all the time and ATS has always come through, especially on short notice, emergency work.

Jody Reimer

Google Review, Winnipeg

Very, very friendly and professional staff. I was looking for a very niche item that no where else in town had. Instead of just saying no sorry, they instead went through the hassle of looking through catalogs to see if what I needed could be ordered. They even went as far as to look online and find me a link for what I needed!!! 10/10 recommend.

Ben Harder

I met one of the flaggers and she shared quite a bit of knowledge on flagging laws and took her job seriously… it made me think ATS traffic is a great company to hire when I need flaggers.
