1.2  Introduction 

The ACTURA Flex 48330 Power system consists of 50A rectifiers, Control Unit, 

Multi-Function Unit (MFU), rectifier shelf and BCU (optional). 

The product is used in base station, small exchange station, satellite 

communication, data communication, and so on, with a strong adaptability to power 

network fluctuation. 

This system is used as a power supply for telecom equipment with system nominal 

voltage of -48V and positive terminal earthed. 

1.3  Features 

The DC power system is easy-to-operate, easy-to-install and easy-to-maintain. Its 

main features are: 

  Rectifier uses APFC technology and therefore its PF is up to 0.99; 

  Wide AC input voltage range of 85~290V; 

  Rectifier efficiency is at least 90%; 

  Extra low EMI of rectifier and excellent EMC performance;
