Article Number: 60203003 AC PowerCube 24 / 4000

The AC PowerCube 24 / 4000 is a professional inverter suitable for continuous operation even under extreme conditions. The AC PowerCube 24 / 4000 makes it possible to switch off the diesel generator for longer periods of time and provide the entire onboard installation with power including, for example, air conditioning, kitchen and refrigeration equipment. As a result, there is less fuel consumption, less noise disruption and fewer running hours for the generator.


  • Industrial electronics based on high frequency switched mode technology
  • Quiet and environmentally friendly
  • As a result, high efficiency (>92%) and a minimum of powerloss
  • Significant cost savings from reduced fuel consumption
  • Great high efficiency = minimal cooling required (cool running)
  • Fan cooled, resistant to high ambient temperatures
  • No ripple effect from AC to battery, with as a result, a stable DC network
