£234.38
The Lovato ATL100 is a compact and reliable automatic transfer switch (ATS) controller designed for monitoring and managing two independent single-phase power sources in industrial and commercial power distribution systems. As part of the advanced Lovato ATL series, this controller provides dependable automatic source switching for applications requiring continuous power availability and supply redundancy.
Designed for panel builders, electrical contractors and automation engineers, the ATL100 offers simple and efficient management of transfer switching systems. Its modular DIN rail format allows fast installation inside switchboards and control panels, while the integrated monitoring functions ensure reliable supervision of incoming power sources.
With support for single-phase 80–300 V AC monitoring and automatic management of two power sources, the Lovato ATL100 is ideal for standby power systems, generator transfer applications and critical power installations requiring uninterrupted supply continuity.
Automatic transfer switch controllers continuously monitor incoming power supplies and automatically transfer loads between primary and backup sources when voltage conditions fall outside preset limits. This ensures continuous operation of critical electrical systems and minimises downtime during supply interruptions.
The Lovato ATL100 is engineered for compact switchboard installations where dependable source monitoring and automatic transfer functionality are essential. Its modular design and simplified operation make it suitable for generators, UPS systems and emergency power applications.
