Rectifiers

Two-Branches and Bus-Tie 

 

 

  • Natural convection cooling
  • Battery Rectifier (BR) for Charging  Lead-acid, Ni-Cd and Sealed Type Batteries
  • Service Rectifier (SR) for Supplyng DC Loads
  • Bus-Tie connection in case of AC voltage loss or failure of one rectifier
  • Optional output diode
  • High efficiency
  • High reliability
