1. 48v rectifier power supply 2. output current 30A 1500w 3. battery charge or power supply for load 4.2 years warranty

  Our company SETEC Power Co.,Ltd, mainly focus on DC/DC converter, DC/AC inverter, battery charger ,AC/DC rectifier power system and solar pump inverter

                 

  Battery Charger 30A(from Generator 220V)

 

  its  function 1: mainly used for battery charge or discharge,or power supply for the communication load,  2:Charging current limit  3: float charge or boost charge  etc

 

Adopted advaned module and design makes battery charger is small in size, which can provide enough power to satisfy the communication requirements with 19″ rack mounting features. It is applicable to all kinds of the exchange room, base stations, satellite communication, data communication, railway and utility power system where electric network fluctuation range is very wide. Battery charger has the advantages of convenient operation, easy installation and maintenance. System rack installation, convenient and flexible expansion. Main features are as below.

 

Rectifier modules used new technology, so the power factor can be 0.99

 

criterion height is 2U,output-current can obey user’s request to design,Max current is 30A. 

 

rectifier modules used soft switch technology,while load rate10% then efficiency can be  87%,50% load rate the efficiency can be above 95%
