Load monitoring
and control interface
UNIVERSAL INTERFACES
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.
Main features
• Plastic casing
• Programming pushbutton and LED on the case
• Connection to bus line with KNX terminal block
• Connection to current transformers by means of a 6-wire screw terminal block
• IP20 protection degree (installed device)
• Weight 20 g
Functional characteristics
• Connection to current transformers EK-TA-... by means of 3 physical inputs
• Possibility to measure (up to) three single-phase or one three-phase lines;
• Possibility to receive power values from bus
• 8 general purpose power thresholds
• 4 4-channel logic functions (AND, OR or XOR)
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-... must be
ordered separately.
