Parameter
Range
Default
Value description
Over (over-
voltage)
40V ~ 60V
58.5V
The “DC Over Voltage” alarm will be raised when the
system DC output voltage is higher than the value of
“Over”
The values of
these three
parameters should
be: Over > Low >
Under
Low (low-
voltage)
45.0V
The DC low voltage alarm will be raised when the system
DC output voltage is lower than the value of “Low”
Under (under-
voltage)
45.0V
The DC under voltage alarm will be raised when the
system DC output voltage is lower than the value of
“Under”
High (high
temperature)
10°C ~
100°C
40°C
The high temperature alarm will be raised when the
detected ambient temperature is higher than the value of
“High”
The value of
parameter “High”
must be higher
than that of
parameter “Low”
Low (low
temperature)
-40°C ~
10°C
-5°C
The low temperature alarm will be raised when the
detected ambient temperature is lower than the value of
“Low”
Load shunt
Y, None
None
Set according to the system actual situation
Shunt Coeff
Dependent on system
type
In the system with a load shunt, this parameter can be set only when the
parameter “Shunt” (as a system type) is set to “Set”

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”
The “Default Volt”
must be lower than
the “Rect Over
Volt”
Default Volt
48V ~ 58V
53.5V
When the communication between the rectifier and the
monitoring module is interrupted, the output voltage of
the rectifier is the default voltage
Walkin Enabled

The output soft start function means the rectifier voltage will rise from 0V to the
“Default Volt” after the “Walkin Time”
Walkin Time

1A ~ 50A
30A
The monitoring module limits the rectifier input current within the limit value
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
