Ensure unmatched connectivity, reliability, and safety. 

More power to you

When you specify TruONETM, you bring a higher level of ease and reliability to your project. Installers can save time with one-wire installation. Facilities managers can streamline service. And everyone can rest easy with superior transfer switch functionality and reliability. 


Safety and Protection
TruONE enables safe emergency manual operation—even under load—without opening the panel door when the HMI is mounted to the ATS frame. The HMI can be detached from the frame for door mounting, offering more flexibility for the panel designer. Best of all, regardless of the HMI installation method, there’s no need for connecting dangerous line voltages to the door, so the risk of operator injury due to equipment malfunction is reduced.

Continuous Operation
TruONE features predictive maintenance, self-diagnostics and customer-replaceable critical modules to simplify service and significantly reduce downtime and service costs.

Data and connectivity
TruONE features cloud-based connectivity through the ABB AbilityTM Electrical Distribution Control System (EDCS). ABB Ability simplifies implementation and use of TruONE in coordination with other ABB devices, ensuring one common user interface and one common software environment. Market-leading modular connectivity with seven communication protocols ensures installability and connectivity now and far into the future.

Reliable in Extreme Conditions
You can be sure TruONE exceeds standard requirements for performance and reliability to bring you dependable operation in even the most challenging electrical, mechanical and environmental conditions. 
TruONE is the only ATS to guarantee safe and reliable operation during dramatic variations in temperature (-25…+70°C) and voltage (160–576 VAC), and it’s tolerant of vibrations (acc. IEC 60068-2-6) and shocks (acc. IEC 60068-2-27). TruONE also has true short-circuit resilience—able to take the hit and remain fully operational after exposure to the most dangerous phenomena to which an ATS can be exposed. Site conditions can change due to unexpected situations, but the performance of TruONE does not.
