Charging batteries
The power supply can be used to charge lead-acid batteries or maintenance-free batteries (SLA or VRLA batteries). Two 12 V batteries connected in series are required.
Instructions for charging batteries:
- Use only matched batteries when putting 12 V types in series.
- Ensure that the ambient temperature of the power supply remains below 40°C.
- Use a 15 A or 16 A circuit breaker or a decoupling 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.
- The reverse current to the power supply is typically 6 mA. This reverse current can discharge the battery when the power supply is switched off, unless a decoupling diode is used.
- Switch the device to "Parallel Use" mode and 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 | 55.6 V | 55 V | 54.3 V | 53.6 V |
Battery temperature | 10°C | 20°C | 30°C | 40°C |
