Rectifier - Battery charger

 
 
CESINEL designs and manufactures industrial Rectifiers-Battery chargers to supply critical DC loads and to charge any type of battery. The typical applications for these equipments are:
  • Power stations and substations
  • Oil, gas and petrochemical plants
  • Water treatment plants
  • Manufacturing plants
  • Transportation

Our Rectifier-Battery charger is based on the standard “12 SCR bridge” power conversion system, thus providing reliability, efficiency and cost-effectiveness. The control board is based on microprocessors of the latest generation, and its front access ensures easy accesibility and maintenance.

The Rectifier-Battery charger standard configuration can be equiped with a wide range of options and customized solutions in order to adapt to the clients’ requirements. It includes input isolation transformer protected by MCCB, and a full set of battery charging methods, with battery voltage/temperature compensation.
