Emerson power system

48V/90A

 

brief introduction

NetSure531 A31 The embedded system is embedded in the high-frequency switching power supply of high frequency switch power supply system miniaturization, Emerson network power rectifier module design of the new generation of high frequency switch based on a high power density and high reliability, the system uses19”Structural design, optional ordinary/High efficiency rectifier module supports energy saving sleep technology and high efficiency-The function of common module mixing can be widely used in the mobile communication networkLTE FTTx and other efficient, green environmental protection network construction needs.

 

System characteristics

l  Small size, embedded installation,3UThe inserted frame supports the outgoing line and the side outlet,2UInserted frame full frontal connection

l  Emerson3Instead of rectifier module, the system has higher power density and higher efficiency

l  System supports energy saving sleep technology and high efficiency-Common module mixing function, more energy saving and environmental protection

l  Wide input voltage range85~300VacThe adaptability of the grid is strong

l  Operating temperature of rectifier module:-40 ~ +80 Environmental adaptability is strong

l  Nondestructive thermal plug, support online maintenance, convenient and quick

l  Perfect battery management function, effectively prolong the service life of the battery

l  provideRS232Net mouth,USBAnd other communication interfaces, flexible networking, remote monitoring can be achieved

 

Application range

l  LTEIndoor coverage power supply

l  FTTxBroadband integrated access power supply

l  Small capacity power supply demand of communication base station
