UPStealth® Uninterruptible Power Supply

We now live in an Always-On ITS world and Departments of Transportation throughout U.S. and Canada have made a commitment to increasing safety with the UPStealth Uninterruptible Power Supply (UPS).  The UPStealth utilizes transformational nickel-zinc batteries to energize intersections, ITS cabinets and ITS data centers when utility power is lost.  

As the fastest growing UPS for ITS, UPStealth offers transportation departments the opportunity to upgrade to an easy-to-install, self-maintained solution with superior performance, environmental and safety advantages over traditional battery backup solutions.



UPStealth® Uninterruptible Power Supply is available for all traffic signal controller and ITS cabinets.


Cabinet Optimization

"The UPStealth’s flexible design is really appealing. I don’t have to buy another cabinet. It just slides into the dead space not being used and other UPStealth configurations can fit under shelves, on a door panel or on the sides of the racks. The fact the battery is green and energy efficient on top of that is just icing on the cake."

Norm Colby. Operations General Supervisor. City of Sacramento.
