Interface CF2 for load monitoring and control

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.
