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, TruONE® stands 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.
