Powermanager lts load shedding automatic transfer
The PowerManager LTS is designed to allow the most efficient use of the generator by monitoring and managing the backed up selected and non-selected circuits. If the generator approaches overload condition, the non-selected circuits are cycled off, allowing the selected circuits to remain powered. This switch is designed to operate with the digital controls that are used on air-cooled and liquid-cooled generators from 8 kW through 45 kW.
The LTS is housed in an aluminum NEMA 3R enclosure. It is service entrance rated at 200 amps and also has a built in 16 circuit priority load center. The main contactor protects the selected priority circuits while the secondary contactor protects the remaining, non-selected circuits located in the existing electrical panel. The cover is side hinged for easy access.
The transfer switch contactor is rated at 250 VAC and is available in single phase configuration only.
