Case Study: Newburyport, MA achieves continuous intersection operation during a Category 3 storm with McCain Inc.'s 48VDC Low-Voltage ATC Cabinet

Mccain’s 48vdc Low-voltage Atc Cabinet Powers Only Working Signals in Newburyport, Ma Until Power Was Restored

Newburyport, MA experienced widespread power outages during Category 3 Winter Storm Stella that left almost all signalized intersections dark and hazardous. To address safety and resilience concerns, McCain Inc tested its Low-Voltage solution — the 48VDC Low-Voltage 350i ATC Cabinet — in a solo intersection pilot approved by MassDOT.

McCain Inc’s 48VDC Low-Voltage 350i ATC Cabinet kept the Old Route 1/Low Street intersection fully operational throughout the outage; 10 hours after discovery the battery was still at 70%, enough for two days of fully actuated operation or two weeks in flashing yellow. As a result, the McCain Inc-equipped intersection was the only one in Newburyport, MA to remain functional during the storm, demonstrating extended battery life and improved public safety.
