Charging batteries

The power supply can be used to charge lead-acid or maintenance-free batteries. (Two 12 V batteries in series).

Instructions for charging batteries:

  • Adjust the output voltage, measured at no load and at the battery end of the cable, very precisely to the end-of-charge voltage.

End-of-charge voltage

27.8 V

27.5 V

27.15 V

26.8 V

Battery temperature

10°C

20°C

30°C

40°C

  • Use a 50 A or 63 A circuit breaker or a blocking diode between the power supply and the battery.
  • Make sure that the output current of the power supply is below the permissible charging current of the battery.
  • Only use matched batteries when connecting 12 V types in series.
  • The reverse current to the power supply (battery discharge current) is typically 35 mA when the power supply is switched off (except when using a blocking diode).
