Rectifier
Current sharing
The rectifiers can work in parallel and share the current. The
unbalanceness is better than ± 5%
Derate by input (at 45°C )
176Vac input, The rectifier outputs 100% power
132Vac input, The rectifier outputs 1400W power
93Vac input, The rectifier outputs 1000W power
85Vac input, The rectifier low pressure power off
Output delay
Output voltage can rise slowly upon rectifier start up. The rise time
is configurable
Fan speed adjustable
Rectifier fan speed can be set to half or full speed
Over-voltage protection
The rectifier provides over-voltage 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 (0.5V above output
voltage, 59V by default), and can be set through the controller
There are two software protection modes, which can be selected
through the software at the host:
1. Lock out at the first over-voltage
Once the output voltage reaches protection point, the rectifier will
shut off and hold that state. It requires manual resetting to restore
the operation
2. Lock out at the second over-voltage
When the output voltage reaches the software protection point, the
rectifier will shutdown, and restart automatically after 5 seconds. If
the over-voltage happens again within a set time (default: 5min.
Configurable through controller), the rectifier will shut off and hold
that state. It requires manual resetting to restore the operation
Manual resetting: Resetting can be done manually through the
controller, or by removing the rectifier from system
Temperature derating
Temperature below 55°C, outputs full power
At 55°C to 65°C, output power is Linear decline in 1,800W;
At 65°C to 70°C, output power is Linear decline in 1,500W;
At 70°C to 80°C, output power is Linear decline in 0W

protection
features
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
