1. Your nameplate color is not we see in the market. Which color is the authentic?

In the past, the ATS we sold to foreign and domestic markets use the classic AISIKAI BLUE . Recently, we use this new light blue for foreign market. Both are authentic.   

 

2. What is the meaning of  CK in our model? Why does some ATS have, some does not?

CK means "Export". Because foreign trade transportation usually has a higher risk of damage than domestic transportation, our workers  take additional measures such as bubble wrap when shipping ATS with CK. Recently, we started using different nameplate colors to distinguish Export goods, and CK may not be used.


6. 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.

7. What's the other control voltage besides 220V AC?

 AC110V, AC280V, DC24V are available. Please consult us for other voltages.

8. 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.  


9. What does accessories list include?

Scews and bolts; A pair of safety protection boards; A handler for manual operation.

10. 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.
