metering in tap-off box

Bus bar systems are increasingly applied in data centres. This is a logical development because bus bar systems ensure very small losses during the transport of power and a high degree of flexibility.
The disadvantages of a bus bar system are that it is somewhat more expensive to install and that very large short-circuit power flows are possible in the 19" cabinets, due to which, you have to take extra account of the short-circuit resistance of the components (fuses!) when selecting your PDU.
Schleifenbauer Products, in collaboration with one of its clients, has developed a metering module that can be built into a branch box of such a bus bar system. Alongside there is an animation in which it can clearly be seen how such a module is built into the tap-off box.The BB meter can be supplied in single-phase and three-phase for both 16A and 32A. The BB meter can only be supplied to installers who can build them into the tap-off boxes. It is therefore not a product intended for end users.
The installer receives the products and installation instructions from us and provides the building-in and the RJ45 connections on the outside of the tap-off box.
Definilink bus bar configuration:

With the Definilink bus bar, only the standard coils in the branch boxes are attached and linked to the branch box with a special connector. With an external Definilink controller, everything can then be measured, just like 'normal' meters. Thanks to the Definilink method, we can provide a solution for all branch boxes. An advantage of the Definilink method is that the controllers can be exchanged without interrupting the power supply. This is clarified in the diagram below.

In this way, it is also possible to postpone investment in metering and then, without interrupting the power supply, connect the meters later. Your electrician only needs to attach the coils and the connectors to the branch box.
