Auto Transfer Switch (ATS) is mainly used in two way power supply system with rated voltage below 400V, AC 50/60Hz, rated current up to 630A, when one power supply is abnormal then it transfers between two power supply system, to ensure the power supply reliability and safety.

The ATS have “Main Power”, “Backup Power” and “Two ways OFF position” with higher breaking and making capacity. It not only can meet normal load transfer, but also can meet high inductive impedance or big motor load transfer.

• RDS2 series ATS
• RDS3 Series ATS
