PRS0500
Rectifier Module, Control Module and Embedded Rack |
Rectifiers
for Telecommunication
 Redundancy technology:
obviously improve reliability of whole system running by the
standby of modules8,
16, or 32xE1
Soft switch technology:
obviously reduce the equipment dimensions, improve switch power,
lower the loss of energy, and improve efficiency and stability of
system running
Power factor correction
technology: increase efficiency, reduce electromagnetic pollution,
and improve the life of components
Load current sharing
technology: obviously lower the ratio of load current of power
supply modules with abnormality, and improve stability of system
running
Electromagnetic
compatibility technology: reduce active and passive
electromagnetic pollution of the equipment, and ensure safe and
reliable running of the communication equipments.
