Parameter Description
Rectifier
Current sharing
Rectifiers can work in parallel and share the current. The unblanceness is better than
±3% rated current. Test current range: 10% ~ 100% rated current
Derate by input (45°C)
The rectifier can output max. power of 5,800W with input voltage of 304Vac ~ 530Vac.
The output power will drop to 50% rated power when the input volatage fall to 304Vac ~
260Vac
Output delay startup
The startup time is configurable through controller. The time is 8s at 90% rated load, and
90s at 100% rated load
Fan controlling
Rectifier fan speed can be increased when the rectifier temperature and output current is
raising. The fan speed will reach full speed when ambient temperature is more than 45°C
or full loads output. If the PFC bus voltage exceeds the normal range, for example in the
case of low bus voltage, the fan will stop to work
Overvoltage protection
mode
The rectifier provides overvoltage hardware and software protection. The hardware
protection point is 59.5V ± 0.5V, and it requires manual resetting to restore operation.
The software protection point is between 56V and 59V, and can be set through the
controller
When the output voltage of rectifier is higher the overvoltage protection point, the rectifier
will shutdown. The overvoltage protection point is between 56V and 59V, and can be set
through the controller. The alarm indicator (red) will be on when rectifier occurs
overvoltage protection. The protection event will be set to the controller which will deal
with this alarm. If the rectifier happens four times overvoltage in 5min, it requires manual
resetting to restore the operation
There are two software setting modes through the controller on rectifier:
1. Restart by hand
2. Restart automatically after overvoltage protection in 5s
Temperature derating
Temperature below 45°C, outputs full power: 5,800W
Temperature above 45°C, outputs power as following::
At 50°C, output power is 5,400W
At 65°C, output power is 4,640W

At AC side
The AC input side can withstand five times of simulated lightning voltage of 5kV at
10/700µs, for the positive and negative polarities respectively. It can withstand five times
of simulated lightning surge current of 20kA at 8/20µs, for the positive and negative
polarities respectively. The test interval is not smaller than 1 minute. It can also withstand
one event of simulated lightning surge current of 40kA at 8/20µs (test with AC cabinet)
At DC side The DC side can withstand one time of simulated lightning current of 10kA at
8/20μs
Other
Safety regulation Compliant with IEC60950
Noise The noise is not more than 60dB (A) when ambient temperature is 25°C
Protection level IP20
Insulation resistance
At temperature of 15°C ~ 35°C and relative humidity not bigger than 90%RH, apply a
test voltage of 500Vdc. The insulation resistances between AC circuit and earth, DC
circuit and earth, and AC and DC circuits are all not less than
10MΩ
Insulation strength
Remove the SPD, controller and rectifiers from the system before the test
AC circuit to earth: 50Hz, 2,500Vac
AC circuit to DC circuit: 50Hz, 3,000Vac
DC circuit to earth: 50Hz, 1,000Vac
