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:

  • Make sure that the ambient temperature of the power supply remains below 45°C.
  • Adjust the output voltage, measured at no load and at the battery end of the cable, very precisely to the end-of-charge voltage.

  • Use a 16A 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.
  • Only use matched batteries when connecting 12V types in series.
  • 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.
