Charging batteries

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

Instructions for charging batteries:

Only use matched batteries when connecting 12V types in series.
Make sure that the ambient temperature of the power supply remains below 40°C.
Use a 10A protective circuit breaker or a decoupling 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.
The reverse current to the power supply is typically 8mA. This reverse current can discharge the battery when the power supply is switched off, unless a decoupling diode is used.
Adjust the output voltage, measured at no load and at the battery end of the cable, very precisely to the end-of-charge voltage. The voltage should be set to 27.8V at 10°C, 27.5V at 20°C, 27.15V at 30°C and 26.8V at 40°C ambient temperature.
