Parameter Description
Rectifier
Current sharing
The rectifiers can work in parallel and share the current. The
unbalanceness is better than ± 3% (R48-1800) or ± 5% (R48-3200/
R48-2900U) rated output current. Test current range: 10% ~ 100%
rated current
Derate by input (at 45°C)
R48-1800:
The rectifier outputs max. 1700W power with input voltage 176Vac.
The rectifier outputs 800W power with input voltage 85Vac
R48-3200/ R48-2900U:
The rectifier outputs 100% power with input voltage 176Vac.
The rectifier outputs 50% power with input voltage 120Vac.
The rectifier outputs 18.75% power with input voltage 85Vac
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 monitoring
module
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 monitoring module), 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
monitoring module, or by removing the rectifier from system
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
Temperature derating
R48-1800:
Temperature below 45°C, outputs full power
Temperature above 45°C, there will be linear derating, that is:
At 55°C, output power is 1,600W
At 65°C, output power is 1,500W
At 75°C, output power is 800W
At 80°C, output power is 0W
R48-3200:
Starts at -40°C; Temperature below 45°C, outputs full power
Temperature above 45°C, there will be linear derating, that is:
At 65°C, output power is 2,320W
At 70°C, output power is 1,450W
At 75°C, output power is 0W
R48-2900U:
At the ambient temperature of:
Below 45°C, outputs full power: 2,900W
Above 45°C, there will be linear derating, that is:
At 55°C, output power ≥ 2,320W
At 60°C, output power ≥ 1,450W
At 65°C, output power: 0W
