1. What will this ATS operate when a power failure occurs?
In general, ATS will transfer to the standby power when the utility power(main power) fails.
Also, ATS will transfer to the utility power when utility power returns. In this way, ATS ensures
you have the continuous power.
2. What's the other control voltage besides 220V AC?
AC110V, AC280V, DC24V are available. Please consult us for other voltages.
3. Can I operate this ATS manually?
Yes, our ATS have both electric and manual mode(switchable using the black button on front panel),
you can operate our ATS using handler.
4. What does accessories list include?
Scews and bolts; A pair of safety protection boards; A handler for manual operation.
5. Does this ATS must work with an ATS controller for automatic transfer?
No, using this ATS alone is sufficient for the automatic transfer between 2 power sources.
But with ATS controller, more functions can be achieved like delay before transfer, voltage detection,
communication and etc.
