The Lovato ATL900 is a premium automatic transfer switch (ATS) controller engineered for advanced management of multiple three-phase power sources in critical industrial and commercial power systems. As part of the high-performance Lovato ATL series, the ATL900 delivers intelligent automatic source transfer, load management and integrated PLC functionality for sophisticated standby power and energy continuity applications.
Designed for electrical engineers, generator specialists and switchboard manufacturers, the ATL900 combines extensive monitoring capability with flexible expansion options and advanced communication functionality. Its large graphic LCD display, built-in RS485 communication and programmable logic architecture make it ideal for complex power distribution systems requiring dependable automation and high operational reliability.
With support for three controlled power sources, two tie-breakers, integrated current monitoring and expandable communication modules, the Lovato ATL900 is suitable for industrial power management systems, generator synchronisation applications and critical infrastructure installations where uninterrupted power continuity is essential.
Automatic transfer switch controllers continuously supervise electrical power sources and automatically transfer loads between utility supplies, generators and backup systems whenever voltage or frequency conditions move outside predefined limits. This ensures operational continuity while protecting sensitive electrical infrastructure and minimising downtime.
The Lovato ATL900 is specifically designed for sophisticated power management applications involving multiple incoming sources and tie-breakers. Its integrated PLC logic, communication expandability and advanced monitoring functions allow engineers to implement intelligent standby power strategies across industrial facilities and critical infrastructure environments.
