If setting to the ‘Speed regulation’ status, the rectifier will regulate the running
speed of the rectifier fan according to the air inlet temperature. If setting to the ‘Full
speed’ status, the fan will run at full speed
Over voltage
restart time
50s to 300s
300s
When the rectifier is over voltage, the rectifier will automatically power off. Power
on the rectifier after a delay of setting time, and judge whether it is still over
voltage. This delay refers to the setting value of the ‘Over voltage restart time’. If
the rectifier is not over voltage in the ‘Over voltage restart time’, it is considered
that the rectifier can work normally. If the rectifier is over voltage within that time,
the rectifier will power off and be locked and cannot power on automatically
Interval start
0 to 10s
0s
The rectifier will output the voltage in a specific sequence and interval. If it is set to
‘0’, it indicates the voltage is output simultaneously
OverVolt Enable
Yes, No
No
If setting to ‘Yes’, it indicates that the rectifier will still power on forcibly and output
the voltage even if it detects there is AC over voltage
