When conducting setting, use ▼ or ▲ key to select one of screens or parameter items to be set, and ◄ or ► to
select the parameter value. Then press ENT key to confirm and save.
The value of DC parameters is described as follows:

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)
-40°C to
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 to
100°C
-5°C
The low temperature alarm will be raised when the detected
ambient temperature is lower than the value of ‘Low’

When the module output voltage is higher than the
setting value of the ‘Module over voltage’ parameter,
the rectifier will generate a module over voltage alarm
The setting value of the
‘Default voltage’ must be
lower than that of the
‘Module over voltage’
Default voltage
48V to 58V
53.5V

Yes, No
No
Load soft start function means that the rectifier voltage increases gradually from
0V to the setting value of the ‘Default voltage’ after the setting value of the ‘Output
