CDR 400 - 8

Back To List
  • Input : 3 x 380 V / 50 Hz 200 KVA
  • Output : 8 x 50 A / 8 x 440 V
  • Circuits per cabinet : Up to 8
  • Parallel work : Yes
  • Formation of starter lead acid batteries- regardless of the specific technology used in the formation of batteries, these type of rectifiers provide charge and discharge during the process. The high output voltage (440 V) allows to manage the charge/discharge of up to 24 twelve volt batteries with one circuit.;
  • Formation of stаtionary lead acid batteries- there is no reason why this equipment can't be used for charging (and discharging, if necessary) different types of stationary batteries (2V, 4V, 6V and 12V) used in telecommunications, as industrial UPS, for renewable enegy sources, etc. ;
