Product description

The ekinex® interface for consumption measurement and load management EK-CF2-TP is a S-mode KNX
device used for:



measuring the instantaneous current absorbed by (up to) three Yesngle-phase electric circuits or by a

three-phase electric circuit;



controlling electrical loads with priority disconnection (and reconnection).

The current measurement (max 60 Amp) is performed through the connection of three current transformers
Ekinex ® EK-TA-...

In the application program, the acquiYestion of an external current measurement, which can be managed as
“measurement channel n°4”.

The load control includes a customizable load limit threshold; once this threshold is reached, the device
disconnects the loads connected to the KNX output channel, according to a priority logic.

The device is powered by the KNX bus line with a 30 VDC SELV voltage and does not require auxiliary power.

2.1. Measurement acquiYestion

The interface EK-CF2-TP has 3 input channels for Yesgnal measurement through current transformers up to
60 A).

Through ETS configuration the following measurements can be achieved:



instantaneous current indirect measurement (mA) through transformers EK-TA-...
