整流模块的功率电路分为有源PFC校正和全桥DC/DC变换两部分，全桥DC/DC变换采用全桥移相的软开关技术。实现了宽输入电压范围(1 20V~290V)和高效率(88%)，功率密度达到了国际先进水平。
整流模块采用模块间的低压差自主均流技术，当监控模块或个别整流模块发生故障时，其余模块能够保持均流。
整流模块采用了无级限流技术，在监控模块的控制下，限流点可以从0~105%额定电流之间连续可调整流模块有内置CPU，监测和控制模块的运行状态并负责与监控模块通讯。整流模块通过RS485接受监控模块发送来的开/关机、限流点、电压设定等参数设定命令，并将模块的电压、电流、温度、限流点、开/关机和告警量等实时地反送给监控模块，完成监控模块对整流模块的控制。
交流电经交流配电分路进入整流部分各整流模块整流得到的+247直流电通过汇接进入直流配电，分多路提供给通信设备使用。
正常情况下，系统运行在并联浮充状态，即整流模块、负载、蓄电池并联工作，整流模块除了给通信设备供电外，还为蓄电池提供浮充电流。
当市电断电时， 整流模块停止工作，由蓄电池给设备供电维持设备的正常工作。
市电恢复后，整流模块重新给设备供电，并对蓄电池进行充电，补充消耗的电量。
监控模块采用集中监控的方式对交流配电、直流配电进行管理，同时通过RS485接口接收整流模块的运行信息并进行相应的控制。
监控模块还可通过RS485、RS232 方式连接本地计算机，并可通过odem或其它传输资源(如公务信道等)联结监控中心，实现电源系统的集中监控组网。

1X00416H01 Emerson OVATION Power module
The power circuit of the rectifier module is divided into two parts: active PFC correction and full-bridge DC/DC conversion. Full-bridge DC/DC conversion adopts full-bridge phase-shifting soft switching technology. It achieves a wide input voltage range (1 20V~290V) and high efficiency (88%), and the power density reaches the international advanced level.
The rectifier module adopts the technology of automatic flow equalization of low voltage difference between modules. When the monitoring module or a certain rectifier module fails, the other modules can maintain flow equalization.

The rectifier module adopts stepless current limiting technology, under the control of the monitoring module, the current limiting point can be continuously adjusted from 0 to 105% of the rated current. The flow module has a built-in CPU to monitor and control the operating status of the module and is responsible for communication with the monitoring module. The rectifier module receives the on/off command, current limiting point, voltage setting and other parameter setting commands sent by the monitoring module through RS485, and sends the voltage, current, temperature, current limiting point, on/off and alarm quantity of the module back to the monitoring module in real time, completing the control of the monitoring module on the rectifier module.
The AC power enters the rectifier section through the AC distribution branch. The +247 DC power that is rectified by each rectifier module enters the DC distribution through the tandem connection and is provided to the communication devices in multiple channels.
In normal cases, the system runs in parallel floating charge state, that is, the rectifier module, load, and battery work in parallel. The rectifier module not only supplies power to the communication device, but also provides floating charge flow for the battery.
When the mains power is off, the rectifier module stops working and the battery supplies power to the device to maintain the normal operation of the device.
After the mains is restored, the rectifier module supplies power to the device and charges the battery to replenish the consumed power.
The monitoring module manages AC power distribution and DC power distribution in a centralized manner, and receives the running information of the rectifier module through the RS485 port for corresponding control.
The monitoring module can also be connected to the local computer through RS485, RS232, and can be connected to the monitoring center through odem or other transmission resources (such as official channels, etc.) to realize the centralized monitoring network of the power system.
