3 Phase Power Meters / Data Loggers

 

Model LDW-6092K

LDW-6092-with-clampsThe LDW-6092K is a complete hand held 3-phase power meter kit, that supports data logging to SD memory card. The versatile meter measures a large number of power parameters for single phase or 3-phase systems. The meter has a multi-line LCD display showing all measured power parameters, and can be configured to record all its measurements to an SD memory card. The unit will integrate the recorded measurements over time intervals ranging from 2 seconds to 2 hours, giving enough flexibility to capture short events or record data over a long period of time.

The meter measures the following parameters in either single phase or 3 phase:

  • Voltage (10 to 600V AC)
  • Current (individual per phase and total – 0.2A to 1200A AC)
  • True Power (kW – individual per phase and total)
  • Energy (kWh – individual per phase and total)
  • Power Factor (individual and average)
  • Apparent Power (KVA)
  • Reactive Power (KVAR)
  • Phase Angle

Measurements are true RMS and take into account the power factor.

The LDW-6092K also includes a full licence of the easy to use yet sophisticated graphing software package DPlot, which makes it easy to open the data files saved by the unit and generate graphs of the measured parameters. This software is a general purpose graphing or analysis tool, so it can be used for other jobs as well.

The complete kit includes the meter, mains adaptor, 3 clamp-on current transformers (switchable range), 4 voltage leads with alligator clips, 2GB SD card, DPlot sophisticated graphing software CD, and a soft carry case.

Typical Applications

  • Spot checking all power parameters, including voltage, current, power, power factor, KVA
  • Monitoring over a period of time for peak demand (by using the data logging function with a short time interval)
  • Checking overall energy usage over a period of time (using the data logging function with a longer time interval)
  • Recording voltage dips and highs from the incoming mains (but not short transients)
  • Energy saving studies – to help identify what is using the most energy within a site
  • On site demonstrations of energy saving systems and appliances – show the customer the actual energy savings on their own site!
