Interface CF2 for load monitoring and control

DIN-Rail mount modules

CODE: EK-CF2-TP

DESCRIPTION

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.

FUNCTIONS / FEATURES
  • 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

 

LOAD MONITORING

  • 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

 

LOAD CONTROL

  • 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
CONFIGURATION AND COMMISSIONING

A detailed description of the parameters can be found in the application manual of the device. Configuration and commissioning require ETS5 2.0 or later versions. ETS application program: APEKCF2TP##.knxprod (## = release).
