Application Background(1)
Background
DC Remote Feeding Power System is used in telecom field. At early period it
was used for PHS (Personal Hand phone System).
As the development of 3G & 4G communication technology, every kind low
power consumption equipment are developed. In particular is widely used for
outdoor base station equipment, Repeater or RRU (Remote Radio Unit). The
requirement of power reliability and safety is much more tight. For telecom-
grade power supply protection needs to consider this type of
communications equipment , DC Remote Feeding Power Systems become
the first choice of telecom carriers.
The volume of RFP is related to RRU. Every RRU need one Remote device.
2-3 Remote devices need one Station Device
Note:RFP= DC Remote Feeding Power System

Market Outlook
Overall Market Outlook in China
Presently, the demand volume of RFP is only 300K -400K sets in year 2012.
The volume of Station Device will be 300-400K sets, and the volume of Remote
Device is 600-1200K sets. In fact the supply volume don’t reach 50%. The
reason is the product stability can’t meet the requirement.
The average increase rate of RFP by 60% in future 5 years.
