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.

1X00416H01

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.
