The R300 series power supplies serve as a constant IU rectifiers in primary switched circuit technology. They generate a regulated output voltage for the battery charge.

A constant DC voltage with a small AC component ensures loading of sealed lead / calcium batteries in both the cycle and in standby parallel operation for maximum battery life.


The power supplies of the R300 series are single phased and have an output power up to 3 kW.

The units are built according to the following standards:
  • EN 60335-2-29
  • EN 55014
  • 60555-3
  • EN 50082-1
  • EN 50081-1
All units are equipped with a 1 kW PFC (Power Factor Corrector), which means the power factor is corrected to almost 1. Therefore they meet the standard EN 61000-3-2.

The input current is a maximum of 3 kW output power at 16 A. Output fuses are installed for devices up to 30 A rated current in the positive line. Be externally protected for all other devices must have the battery in standby parallel operation and the consumer.

The protection of the battery should be done for safety reasons, in accordance with the VDE regulations, as close to the battery. the lines between the battery and the backup should be double insulated. Upon request, the fuses are installed in a separate 3-U rack.
