protection
Stop when 250% of rated output current is exceeded
Overvoltage protection Stop when the main circuit DC voltage is above 820 V
Undervoltage protection Stop when the main circuit DC voltage is below 350 V
Overheat protection Protection triggered when the inverter bridge gets
overheated.
Overload protection Stop after running at 150% of rated current for 60
seconds (for MD500T450G-INT, stop after running at
130% of rated current for 60 seconds)
