ATS 1.1
Automatic Transfer Switch Units - ATS Series

Simultaneous monitoring of Mains and Generator Bus-bars

ATS 1.1 is a dedicated Load Transfer Control switch which allows independent control of Load and Generator, feeding the Load from either Mains or Generator bus-bars, whichever is available, with Mains bus-bar priority.

ATS1.1 is a Load Transfer Control Switch, which monitors the Mains Bus-Bar voltages and transfers the load if the voltage limits fall beyond required tolerances. These units can be used with any two voltage bus-bars, where the load is required to be controlled according to their availability. All three phase voltages are monitored on the mains bus-bar side and each phase can have independent upper and lower voltage limits. ATS1.1 is designed with 2 auxiliary outputs and 3 auxiliary inputs. T... »

ATS1.1 is a Load Transfer Control Switch, which monitors the Mains Bus-Bar voltages and transfers the load if the voltage limits fall beyond required tolerances. These units can be used with any two voltage bus-bars, where the load is required to be controlled according to their availability. All three phase voltages are monitored on the mains bus-bar side and each phase can have independent upper and lower voltage limits.

ATS1.1 is designed with 2 auxiliary outputs and 3 auxiliary inputs. These i/o ports can be configured from the device menu for peripheral device control.

The unit allows the user to crank the generator on for testing or periodical maintenance. This test function can be executed with or without load transfer, allowing testing for the transfer switch at the same time. Normal system operation is maintained in the Automatic mode.

During operation, mains or generator phase voltage can both be monitored on the controller display, hence avoiding extra AC voltmeters to be used on the panel. All voltage values are displayed in True RMS values with high reading accuracy.

All unit parameters can be adjusted from the device configuration menu and all program parameter values can be seen on the controller display. The units can also be programmed to control the engine cooldown function, hence allowing simple engine starter units to be used with small capacity generator sets.
