PA2640 Three Phase Harmonics & Power Analyzer

Multi-Channel & Harmonics Power Analyzer

pa2640 The PA2640 is a three phase power analyzer & harmonics analyzer, additionally it is three single phase power analyzers in a single chassis with a single user interface. The PA2640 Harmonics & Power Analyzers may have up to 4 channels installed, which may be any combination of channel cards and with any combination of available current input options. Multiple PA2640 Harmonics & Power Analyzers can be Ethernet connected to make simultaneous multi channel measurements, useful where power analyzer measurements are needed in multiple locations, where close proximity to the load is required.

Channels may be individually configured, in effect as 3 virtual power analyzers.

Each PA2640 channel can be independently configured for 1ph, 2ph, 3ph 3W, 3ph 4W, multi-channel wiring configurations, signal filtering, default measurement coupling, display results smoothing and efficiency grouping. Voltage and current input channels may be optionally synchronized to each other.

Product Features:

  • PA2640 has MU option (Multi-Unit Option) which allows the connections of up to 50 units, useful to perform synchronous Efficiency Measurements on Three Phase Input / Three Phase Output power conversion devices
  • Offers 1-4 simultaneous channels – all measuring Vrms, Vpk, Arms, Apk, Acf, A inrush, PF, W, VA, VAr, THD, THD+N, V Harmonics, A Harmonics
  • Allows input/output efficiency and power loss…for example testing variable speed drives, electric lighting and power supplies
  • Ideal for Avionics
  • It is accurate with waveform distortion (accurate with non sinusoidal waveshapes)
  • DC-1MHz bandwidth
  • 0.03% basic accuracy
  • Color display with Graphs/Bargraphs/Plots/Data logging
  • PC software available
