Interface CF2 for load monitoring and control

Interface for load monitoring and control that can be used for:
- the instantaneous current measurement absorbed by (up to) three single-phase electrical circuits or one three-phase electrical circuit;
- the control of electrical loads with priority detachment (and re-attachment).
The current measurement is carried out by connecting up to three EK-TA -... current transformers. Load control includes a configurable load limit threshold at which the device detaches, by priority, electrical loads connected to output channels of KNX actuators. The device is powered by the KNX bus line with a SELV voltage 30 Vdc and does not require auxiliary power. Mounting in wall box or on 35 mm rail (EN 60715) with the support EK-SMG-35 included in the delivery. To be used in KNX installations for home and building automation.

• Connection of EK-TA-... current transformers through 3 physical inputs
• Possibility of measuring of (up to) 3 single-phase lines or 1 three-phase line
• Possibility to receive the power value (W) from the bus
• 8 power thresholds (W) for generic uses (e.g. activation of loads dependent on the generation of electricity from a photovoltaic system)
• 4 logic functions (AND, OR o XOR) with 4 inputs

• Indirect measurement of instantaneous current (mA) through EK-TA-... transformers
• Calculation of instantaneous power (W and kW)
• Counting of the total electric energy (kWh)
• Sending on the bus measured values of current, power and energy

• Possibility to manage independently up to 8 loads for each measuring channel
• Power thresholds (W) for load management and corresponding hysteresis (W) settable separately for each measuring channel
• Sending on the bus of threshold overrun signal
• Possibility of selective exclusion from the bus of loads to be controlled
• Delay time (s) for load deactivation and reactivation settable separatately for each channel

A detailed description of the parameters can be found in the application manual of the device. Configuration and commissioning require ETS4 2.0 or later versions. ETS application program: APEKCF2TP##.knxprod (## = release). Available languages: English, French, German, Italian
