Phase Out

Interface CF2 for load monitoring and control

Description

The Ekinex® EK-CF2-TP interface for load monitoring and control is a KNX devices which can be used to:

•measure the instantaneous current absorbed by (up to) three single-phase or one three-phase electrical circuits;
•control electrical loads with priority disconnection and reconnection.

The current measurement is performed by means of max three Ekinex® EK-TA current transformers. The device is powered by the KNX bus and does not require auxiliary power supply. Flush-mounting or mounting on a standard 35 mm DIN-rail by means of a support included in the delivery.

Load monitoring

•Direct measurement of instantaneous current by means of transformers EK-TA
•Calculation of instantaneous power
•Total electricity metering
•Sending on the bus of measured current, power and energy values

Load control

•Possibility to independently handle up to 8 loads for each channel
•Configurable power threshold for load control and related hysteresis
•Sending on the bus of an indication when the threshold is reached
•Possibility to exclude loads from the bus
•Disconnection and reconnection delay independently configurable for each channel

Power supply

•30 Vdc power supply by KNX bus
•Current consumption from bus < 10 mA

Delivery

Delivery includes a terminal block for connection to the bus and a support for mounting on a standard 35 mm DIN-rail. Current transformers EK-TA (page 151) must be ordered separately.
