With voltage sag and complete voltage loss protection function.
Strong overload capacity, support DC start.
Has perfect anti-DC backflow and DC output control function.
System intelligence, modularization, easy operation and maintenance
Voltage sags are generally caused by failures of power grids and substation facilities or sudden large changes in loads. In some cases, there may be two or more consecutive sag or swell. If the voltage sag is too long, the equipment will stop abnormally, a large number of products will be scrapped, the yield rate will be greatly reduced, and huge economic losses will be caused.
