Intelligent power distribution for power supply, data centers and telecommunications

ControlPlex®Rack’s modular design ensures optimal flexibility and can be perfectly adjusted to application requirements. The basic configuration consists of a Power-D-Box® CP and the ESX300-S electronic circuit protectors. Depending on the application requirements, the system can optionally be extended with the RCI10 Remote Control Interface for convenient remote access, the RSI10 Remote Signalling Interface for reliable potential-free signalling and the EAI300 External Alarm Interface for transparent integration of sensors.


  • Highest system availability thanks to selective overcurrent protection with integral current limitation
  • Remote control, monitoring and diagnosis of connected loads
  • Recording of measuring values (current, voltage) and comprehensive diagnosis
  • Flexibility through modular design, allowing easy adjustment to your application requirements
  • Compact and service-friendly design
  • Ease of integration into existing management systems

Basic modules:

Power-D-Box CP

The Power-D-Box CP is a modular power distribution system for up to 19 load channels. The sophisticated design helps save valuable mounting time.
