TruONE. A critical breakthrough for critical power.

The new TruONE is the world’s first true all-in-one automatic transfer switch, engineered to incorporate switch and controller in one seamless unit. Performance tested beyond standard requirements, TruONEstands ready to ensure the steady delivery of critical power at all times.

Its self-contained design reduces the number of wires and connections, which speeds installation and ensures best-in-class reliability. Its predictive maintenance and modular components reduce downtime and service costs. And its advanced connectivity is ready for the future. In addition, unlike typical ATS solutions, TruONE allows emergency manual operation under load for immediate power restoration in the event of equipment malfunction. 

TruONE represents a major shift in engineering and a critical breakthrough for critical power.
