8、 模块双重供电
整流模块R48-2900U特点:
1、输入电压宽范围限功率:功率降额输入电压范围：85Vac～176VA
不工作承受大静态电压：415Vac
额定输入电流：＜16A@2900W
大输入电流：＜19A@2900W/176Vac
输入冲击电流：<30A
2、输出限功率、短路限流
3、热插拔，自适应
4、双重温度限功率，过温保护
5、 DSP软件均流
l与平均电流的差值< ±1.5A
l模块内部处理器DSP均流控制.
–平均电流模式
–恒定电压控制
–模块自主控制
–模块故障不影响均流
–不均流告警
?黄色指示灯:均流误差超过8A
?红色指示灯: 没有输出或误差超过10A
l大可并联48个
l无需均流线
l使用CAN总线，确保所有模块正常通信即可
6、过压关机，自动重启动
l硬件过压保护：
–59.5V。需要人工启动。
l软件过压保护
–监控设置：56-59V
–软件过压保护模式有两种，可以通过后台维护软件选择：
A.一次过压锁死模式
当输出达到软件保护点后，模块关机并保持，需要人工干预方可恢复工作；
B.二次过压锁死模式
当输出达到软件保护点且输出电流大于5A时，模块在关机5秒钟后重新开机，如果在设定时间内（默认为5分钟，可设）发生第二次过压，模块关机并保持，需要人工干预方可开机。
–如果整流模块输出电流小于5A（额定输出10%）时，整流模块不关机。
–人工干预方法：通过监控模块复位整流模块，或从电源系统上脱离整流模块来复位。

8. Modular dual power supply
Rectifier module R48-2900U features:
1. Input Voltage Wide Range Limited Power: Power Reduction InputVoltage Range: 85Vac~176VA
Not working to withstand high static voltage: 415Vac
Rated input current:<16A@2900W
Large input current:<19A@2900W/176Vac
Input impulse current:<30A
2. Output Power Limitation, Short Circuit Current Limitation
3. Hot swap, adaptive
4. Dual Temperature Power Limit and OvertemperatureProtection
5. Software current sharing of DSP
The difference between L and average current is <+1.5A
L module internal processor DSP current sharing control.
- Average Current Mode
Constant Voltage Control
Modular autonomous control
Module failures do not affect current sharing
- Non-uniform flow warning
Yellow indicator: current sharing error more than 8A
Red indicator: No output or error exceeding 10A
L Large parallel connection 48
L No streamline
Use CAN bus to ensure that all modules communicate normally.
6. Overvoltage shutdown, automatic restart
Hardware Overvoltage Protection:
59.5V. Manual startup is required.
Software Overvoltage Protection
Monitoring settings: 56-59V
There are two modes of software over-voltage protection, whichcan be selected through background maintenance software:
A. One-time Overvoltage Lock-up Mode
When the output reaches the software protection point, themodule shuts down and maintains, requiring manual intervention toresume work.
B. Secondary Overvoltage Locking Mode
When the output reaches the software protection point and theoutput current is greater than 5A, the module restarts after 5seconds of shutdown. If the second overvoltage occurs within theset time (default is 5 minutes, it can be set), the module shutsdown and maintains, manual intervention is needed to start.
If the output current of the rectifier module is less than 5A(rated output 10%), the rectifier module will not shut down.
Artificial intervention: reset the rectifier module bymonitoring module or disconnect the rectifier module from the powersystem.
