4、更换整流模块注意事项

1．检查新整流模块是否有损坏。

2．松开整流模块的把手固定螺钉。

3．按压整流模块把手，待把手弹出后抓住把手将整流模块拉出机架。此时请尽量小心，刚刚退出工作的模块外壳表面温度还很高，注意

抓紧模块以免跌落损坏。

4．抓住新整流模块把手，缓慢将整流模块推进到插框，确保输入、输出插座连接良好。整流模块运行指示灯经过短时延迟后会点亮，风

扇运转。

5．检查新的整流模块工作是否正常。包括：监控模块是否能识别新整流模块；是否和其他整流模块均流；当重新拔出该整流模块时，观

察监控模块上是否有相应告警。若各项检验都正常，则更换上的整流模块运行正常。

6．将把手推进前面板以固定该整流模块。

7．固定整流模块的把手固定螺钉。

s. When the module is inserted into the system, it will not cause the disturbance of the system output voltage. Replacement t

ime of module is less than 1 minute.

B. Digital current sharing: Rectifier module adopts advanced digital current sharing technology, without monitoring modul

e, it can automatically e current between modules, and the unbalance of current sharing is less than 1.5A.

C. Input limited power control: According to the change of input voltage and output voltage, the rectifier module adopts adv

anced limited power control method. The conversion point is 176V. When the input voltage is 176Vac~290Vac, the module c

an output high power; when the input voltage is 85Vac~176Vac, it can not only ensure the large load demand, but also ensu

re the reliable operation of the module when the input voltage is low.

4. Notices for Replacing Rectifier Module

1. Check whether the new rectifier module is damaged.

2. Release the handle screw of the rectifier module.

3. Press the handle of the rectifier module and pull the rectifier module out of the rack when the handle pops out. At this tim

e, please be as careful as possible. The surface temperature of the shell of the module just quit work is still very high. Pay att

ention to grasping the module to avoid falling and damage.

4. Grasp the handle of the new rectifier module and slowly push the rectifier module into the socket to ensure that the inpu

t and output sockets are well connected. The rectifier module operation indicator lights up after a short delay, and the fan ru

ns.

5. Check whether the new rectifier module works properly. Including: whether the monitoring module can identify the new re

ctifier module; whether it shares the current with other rectifier modules; when the rectifier module is re-pulled out, observ

e whether there are corresponding alarms on the monitoring module. If all the tests are normal, the replacement rectifier mo

dule will run normally.

6. Push the handle into the front panel to fix the rectifier module.

7. Handle fixing screw for fixing rectifier module.

3. Main functions and characteristics of R48-1000 high frequency switching power supply module

A. Hot plug-in: The rectifier module adopts non-destructive hot plug-in technology. Its output and input have soft start unit

s. When the module is inserted into the system, it will not.

The disturbance of system output voltage is caused. Replacement time of module is less than 1 minute.

B. Digital current sharing: Rectifier module adopts advanced digital current sharing technology, without monitoring modul

e, it can automatically e current among modules, and the current sharing is uneven.

The scale is less than 1.5A.

C. Input limited power control: According to the change of input voltage and output voltage, the rectifier module adopts adv

anced limited power control method. Transformation point in

176V. When the input voltage is 176Vac290Vac, the module can output the maximum power; when the input voltage is 85Va

c176Vac, the module can output the maximum power.

It not only guarantees maximum load demand at low input voltage, but also ensures reliable switching power supply for mo

dules.
