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.
