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 30 A or 32 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 return current to the power supply (battery discharge current) is typically 9 mA when the power supply is switched off (except when using a blocking diode).
