Telecom FIT-FORM-FUNCTION Retrofitting of DC Power Supply Systems

Modernization (retrofitting) of DC power supply systems

FIT-FORM-FUNCTION program – Comparison of annual values
Comparison of annual values (power loss and CO2) of 6.0 kW DC power supply systems

During the last few years, the BENNING company has invested particularly in the development of highly efficient power supply systems for an energy-saving and safe operation of systems for information and communication technology (ICT).

Here, the focus was on increasing the efficiency with regard to the conversion of AC current into DC current for rectifiers and of DC current into AC current for inverters and UPS systems.

Now, BENNING offers the FIT-FORM-FUNCTION modernization of existing DC power supply systems (made by BENNING) by replacing older rectifier plug-in modules with modern TEBECHOP SE devices.

Modernization is possible by easy plug & play installation without any downtime.

As shown in right image, the new TEBECHOP SE devices reduce the system power loss by more than 50 %. The following example shows the possible savings regarding electric energy and CO2 emissions of a DC power supply  system after the modernization with TEBECHOP SE rectifier plug-in modules.

Your advantages at a glance:

  • increased energy efficiency
  • reduction of electrical energy costs
  • reduction of CO2 emissions
  • conservation of resources by re-utilizing the existing system infrastructure (cabinet, monitoring, cabling, fuses etc.)
  • lower investment costs compared to new systems
  • improved system availability

The following TEBECHOP SE rectifier plug-in modules are available for the modernization of BENNING power supply systems:

1. TEBECHOP 2000 SE-712 rectifier plug-in module of 1/4 19“ and 48 V - 40 A for the replacement of 1/4 19“ rectifier plug-in modules of 48 V - 33 A

2. TEBECHOP 2000 SE-753 rectifier plug-in module of 1/6 19“ and 48 V - 40 A for the replacement of 1/6 19“ rectifier plug-in modules of 48 V - 50 A

3. TEBECHOP 12000 SE-127 rectifier plug-in module of 19“ and 48 V - 225 A for the replacement of older rectifier plug-in modules of 48 V - 225 A with the same mechanisms and connection configuration.

Retrofitting of the rectifier systems by means of the  rectifier plug-in modules listed under item 3 requires wiring work in the rectifier cabinet (addition of neutral conductor).
