2、R48-1000高頻開關電源模塊主要功能和特點
a.熱插拔：整流模塊采用無損傷熱插拔技術，其輸出和輸入都有軟啟動單元，當模塊插入系統(tǒng)時，不會引起系統(tǒng)輸出電壓的擾動。更換模塊時間小于1分鐘。
b.數(shù)字化均流：整流模塊采用先進的數(shù)字化均流技術，無需監(jiān)控模塊，模塊間可以自動均流，均流不平衡度小于1.5A。
c.輸入限功率控制：整流模塊根據(jù)輸入電壓和輸出電壓的變化，采用先進的限功率控制方法。轉(zhuǎn)換點在176V。當輸入電壓在176Vac～290Vac時，模塊可以輸出大功率；當輸入電壓在85Vac～176Vac時，使其在低輸入電壓時既保證大負載需求，又能保證模塊的可靠工作
4、更換整流模塊注意事項
1．檢查新整流模塊是否有損壞。
2．松開整流模塊的把手固定螺釘。
3．按壓整流模塊把手，待把手彈出后抓住把手將整流模塊拉出機架。此時請盡量小心，剛剛退出工作的模塊外殼表面溫度還很高，注意抓緊模塊以免跌落損壞。
4．抓住新整流模塊把手，緩慢將整流模塊推進到插框，確保輸入、輸出插座連接良好。整流模塊運行指示燈經(jīng)過短時延遲后會點亮，風扇運轉(zhuǎn)。
5．檢查新的整流模塊工作是否正常。包括：監(jiān)控模塊是否能識別新整流模塊；是否和其他整流模塊均流；當重新拔出該整流模塊時，觀察監(jiān)控模塊上是否有相應告警。若各項檢驗都正常，則更換上的整流模塊運行正常。
6．將把手推進前面板以固定該整流模塊。
7．固定整流模塊的把手固定螺釘。

2. 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 units. When the module is inserted into the system, it will not cause the disturbance of the system output voltage. Replacement time of module is less than 1 minute.
B. Digital current sharing: Rectifier module adopts advanced digital current sharing technology, without monitoring module, it can automatically equalize 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 advanced limited power control method. The conversion point is 176V. When the input voltage is 176Vac~290Vac, the module can output high power; when the input voltage is 85Vac~176Vac, it can not only ensure the large load demand, but also ensure 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 time, please be as careful as possible. The surface temperature of the shell of the module just quit work is still very high. Pay attention 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 input and output sockets are well connected. The rectifier module operation indicator lights up after a short delay, and the fan runs.
5. Check whether the new rectifier module works properly. Including: whether the monitoring module can identify the new rectifier module; whether it shares the current with other rectifier modules; when the rectifier module is re-pulled out, observe whether there are corresponding alarms on the monitoring module. If all the tests are normal, the replacement rectifier module 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 units. 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 module, it can automatically equalize 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 advanced 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 85Vac176Vac, 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 modules.
