Central Energy Converter

The  CEC4L350WGAC  is  part  of  Alpha Innovations solution  for  remote  powering  of  telecommunication equipment located in remote sites. It is intended for use on the telecommunication centre side, or in a street cabinet.

 

The  CEC4L350WGA  is  derived  from  the  CEC4L320  that includes  four  fully  independent,  fully isolated DC/DC up converters, each feeding one Plain Old Telephone Service (POTS) copper pair with 350  VDC.  The  output  current  per  converter  is  limited  under  60  mA,  to  comply  with  the relevant standards (IEC60950-21).

 

Each converter (or its subrack) includes detections for defectives POTS and POTS not connected to a Remote Site. In this case, the feeding voltage is reduced below 50 VDC (protection mode).
