ACCESSORIES FOR CHANGEOVER SYSTEM
Automatic Transfer Switch
Automatic Transfer Switch is used in standby power applications.
ATS will monitor the voltage and frequency of the incoming AC mains (utility) supply and in the event of a failure will issue a start command to the generator
control system.
ATS is designed to monitor the incoming AC mains supply (1 or 3 phases) for under/over voltage and under/over frequency. Should any of the parameters fall out
of limit, ATS will issue a command to the generating set controller.
Once the generator set is available and producing an output within limits, ATS will control the transfer device and switch the load from the mains (utility) to
the generating set.
When the mains (utility) supply returns to within limits, the module will command a return to the mains (utility) supply and shut down the generator after a
suitable cooling run. Various timing sequences are available to prevent nuisance starting or unnecessary supply breaks.
Product Features
ATS has back-lit LCD with 4 line text display which shows system status and indicates any system warnings.
Red and green LEDs indicate the operational status of the network. Moreover ATS has USB, RS232 e RS485 outputs.
ATS is supplied pre-configured with default values which, if necessary, can be easily modified directly from the front panel.
In the absence of DC power supply, a power supply unit is available to be ordered separately (GWD8887).
