  • 3-Phase Power Measuring System "Quick Connect"

  • Innovative connection of 3-phase current transformer sets to a multifunctional power meter
  • Current transformers

  • The multifunctional meters MPR 3 (72 x 72 mm) and MPR 4 (96 x 96 mm) in conjunction with the current transformer set ASKDS are specially designed for the monitoring of equally or unequally loaded 3- or 4-phase networks in building technology. All relevant data can thus be measured and displayed.

    Your benefits of “Quick Connect":
    • • Drastically reduced labour time (and therefore costs) due to
    •   the quick and easy wiring
    • • Avoiding faulty connections due to simple “Plug ’n‘ Play“ technology
    • • Higher security and less down time due to integrated protective
    •   circuits, which enable to connect the current transformer live
    • • Large range of primary currents from 60 to 1250 A with
    •   only three different transformer designs
    • • Two multifunctional power meters to choose from
    •   (72 x 72 mm & 96 x 96 mm)

– Quick – easy – efficient –
  • -   Much quicker installation than with three conventional transformers
  • -   Easier wiring by 8-pin RJ45-connector instead of 6 separate wires for conventional transformers
  • -   Allows efficient setup of multifunctional power measurement in conjunction with our meter MPR 3 (72 x 72 mm) or MPR 4 (96 x 96 mm)
 
Description
  • -   Current transformer set designed for use with our multifunctional meters type MPR 3 (72 x 72 mm) and MPR 4 (96 x 96 mm)
  • -   Transmission of the measured values to the meter by means of a modified RJ45 interface via standard CAT5 patch cable (available in
  •     different lengths up to 5 m)
  • -   All transformers can be operated open due to an integrated protective circuit
  • -   3-phase current transformer sets designed for a near switch installation in the range of a large number of standard circuit breakers
Description
  • -  Easy connection of the 3-phase current transformer set ASKDS to the 330 mV voltage input for primary currents from 60 A up to 1250 A
  • -  Via adapter also connectable to split core current transformers type KBR 18/32/44 with 0…333 mV output
  • -  Replacement of a large number of analogue meters and thus considerably lower wiring costs
  • -  Storage of minimum and maximum values enables monitoring and fault analysis
  • -  Digital input and output as well as an S0 pulse output allow integration in an energy management system
  • -  Additional interface: Modbus-RTU (RS485)

Measured values
With the multifunctional power meter MPR 3 the following measured values can be recorded:
-  Instantaneous values of current, voltage, frequency and power factor
-  Active power, apparent power and reactive power per phase as well as for the entire network
-  Minimum and maximum values of current, voltage, active and reactive power, power factor per phase and for the entire network
-  Optionally the distortion factor of current and voltage can be displayed
 
Additionally integrated are one 4-quadrant energy meter for each active and reactive power, two operating-hours counters as well as one phase sequence indicator are integrated.
One of the operating-hours counters can be reset manually.
 
The user-friendly operation of the device is intuitive via four buttons and the menu guide in the display.
 
All mentioned outputs are galvanically separated from the measuring inputs and the auxiliary voltage.
