You can also choose the generator exerciser load mode, to test the generator on load or off-load. It is applied to the place where generator is not frequently used. 3, Under manual mode, by press "+" button to start or stop the generator manually. 4, High and low Frequency (Hz) protection. 5, ATS setting menu with password protected. RDS3 Series PC class dual power Auto transfer switch, 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 abnormal, then it transfer between two power supply system, to ensure the power supply reliablity and safety. The ATS have " Main Power", "Backup Power" and "Two way OFF" positions, 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, meanwhile due to have high short time withstand current capacity, no need special SPCD, doesn't affect the selective of inside circuit, meanwhile it also can meet the application at big capacity power supply side.
