Charging batteries

The device can be used to charge lead-acid or maintenance free batteries. Two 12V SLA or VLRA batteries are needed in series connection.

Instructions for charging batteries:

  • Ensure that the ambient temperature of the device is below 45°C.
  • Set the output voltage (measured at no load and at the end of the battery cable) very precisely to the end-of-charge voltage.

  • Use a 16A circuit breaker or blocking diode between the device and the battery.
  • Ensure that the output current of the device is below the allowed charging current of the battery.
  • Use only matched batteries when putting 12V types in series.
  • The return current to the device (battery discharge current) is typ. 10mA when the device is switched off except in case a blocking diode is utilized.
  • Do not use the devices for battery charging in mounting orientations other than the standard mounting orientation or in any other condition where a reduction of the output current is required (e.g., altitude).
