Charging batteries
The power supply can be used to charge lead-acid or maintenance free batteries. (Two 12V batteries in series)
Instructions for charging batteries:
- Set the output voltage (measured at no load and at the end of the battery cable) very precisely to the end-of-charge voltage.
End-of-charge voltage | 27.8V | 27.5V | 27.15V | 26.8V |
Battery temperature | 10°C | 20°C | 30°C | 40°C |
- Use a 50A or 63A circuit breaker (or blocking diode) between the power supply and the battery.
- Ensure that the output current of the power supply is below the allowed charging current of the battery.
- Use only matched batteries when putting 12V types in series.
- The return current to the power supply (battery discharge current) is typ. 18mA when the power supply is switched off (except in case a blocking diode is utilized).
