Power factor
≧
0.99
Advanced Protection Features
Input reverse, under-voltage, over voltage protection
Output protection

Operating mode
AC mode (Default)
：
AC utility power is the main source. DC
power is the secondary source. PFC>0.99. Max efficiency 95%.
When the AC utility abnormal, the switching time is 0 second.
AC Ratio mode
：
DC and AC input at same time. The percentage
of AC and DC load can be assigned to 100%. If AC set 70%, then
remaining 30% is DC.
Note
：
The AC input power must be higher than 300W after assigning DC and AC ratio.
DC mode
：
DC power is the main source. AC utility is the
secondary source. THD<3%, Max efficiency is 91%. The
switching time between AC and DC power is 0 second.
