” or “

” to 

select the parameter value. Press “ENT” to confirm and save. 

2. The value description of the parameters is listed below: 

Parameter  

Range 

Default 

Value description   

Rect Over Volt  56V ~ 59V  59V 

The rectifier over voltage alarm will be 

raised when the rectifier output voltage is 

higher than the “Rect Over Volt”   

Default Volt 

48V ~ 58V  53.5V 

 

The “Default Volt” must be 

lower than the “Rect Over Volt” 

Walkin Enabled  Y, N 

N 

Walkin Time 

8s ~ 128s 

10s 

The output soft start function means the rectifier voltage will rise from 0V 

to the “Default Volt” after the “Walkin Time”     

Fan Speed 

Full Speed, 

Half Speed 

Half 

speed 

When set to “Half Speed”, the rectifier will regulate the fan speed 

according to the temperature. When set to “Full Speed”, the fan will 

operate at full speed   

HVSD Time 

50s ~ 300s  300s 

The rectifier will shut off automatically upon over-voltage, and restart after 

a certain delay to see whether it is still over-voltage then. That delay is set 

through the parameter “HVSD Time”. If the rectifier’s output voltage is 

normal within the delay, the rectifier is regarded normal; otherwise, the 

rectifier will be locked out and auto-restart function will be disabled
