BC 500 RT

The automatic battery chargers of the series EA-BC 500 are suitable for charging lead acid batteries with a capacity up to 300Ah. The units operate using the I-U-U characteristics.

The empty battery is first charged in constant current mode until the rated voltage is reached. There follows a boost charge at constant voltage, limited to one hour. Thereafter the charger switches to trickle charge.

Three LEDs on the front are indicating the actual status of the charging mode.

Key Features:

  • Wide input voltage range 90...264V with active PFC
  • Output powers: 150W up to 300W
  • Battery voltages: 12V, 24V, 36V and 48V
  • Charging currents: 5.5A up to 20.5A
  • I-U-U charging characteristic
  • Short-circuit and reverse polarity protection
  • Overtemperature protection (OT)
  • Including adaptor for wall mount
  • Safety EN 60950
