PRODUCT
FEATURES
Low cost of ownership with 2 year parts and labor warranty; 2 year accuracy specs and recommended calibration cycle. Reliable
state of the art fully solid‐state design with 2.9GIPs RISC processing and FPGA based sampling control
Large, high‐resolution color display shows all the data you want with an easy‐to‐use touchscreen user interface to get you up
and testing in no time
Highest precision measurements with industry‐leading noise floor and linearity and up to 100 readings per second with no
reduction in accuracy (up to 500/sec with reduced accuracy with W type channels).
Extremely wide dynamic range allows signals with crest factors to over 100:1 to be measured with full accuracy without having
to reconfigure, and allows range‐less operation (within each shunt) providing truly gapless measurements with varying signals
and is one less thing for you to configure and worry about
All configured measurements are always performed, no need to reconfigure for specific results
Measurements of low power meeting the requirements of EN50564:2011 are built into the XT2640 as standard. A computer is
not needed
Harmonic and Spectrum Analysis of voltage, current and power on all four channels for frequencies up to 435kHz (W type
channels) or 115kHz (S, L or A type channels). Harmonic analysis of up to 500 harmonics (option H500) or 100 harmonics
(standard).
Regulatory harmonics assessment of EUTs is available as an option (option EN) to the applicable requirements of EN61000‐3‐2,
EN61000‐3‐12 and EN61000‐4‐7. The EUT assessment is built‐in to the XT2640 and no computer is required. Each set of
measurements made during an assessment is able to be reassessed to any additional classifications required.
Front Panel USB Drive Interface for portable flash drives or hard disc drives –
Data log to a file in CSV or binary formats at up to 500 per second
Export a tabulation of historically saved data – needs no prior knowledge of the data to be recorded
Save an image of the screen – great for engineering record keeping
Import and export configurations – great for sharing a configuration between units or having your own configuration
Import and export harmonics limits – makes it easy to switch between different harmonics requirements
Export CSV format tabulations of measurement results, harmonics, spectrum, or scope waveforms – makes generating your
own reports easy without mistakes
Export CSV format complete tabulations of EN61000‐3‐2 and ‐12 assessments – makes generating your own reports easy
without mistakes
Internal non‐volatile memory of over 2Gbyte size for high speed data logging at rates up to 500 per second.
Not a “one size fits all” with the extra purchase cost, operating cost, and reduction in performance that entails – you only have to
pay for of the capabilities and performance you want ‐
Up to four power measurement channel cards each of four different channel card types in any combination in a single
XT2640 ‐
S ‐ Provides 0.1% accuracy, 1MHz class bandwidth and 22bit sampling
A ‐ Provides world class 0.03% accuracy, 1MHz class bandwidth and 24bit sampling
L – Same as the A type but optimized for lower voltage applications such as AC:DC and DC:DC power supplies
W ‐ Provides 0.1% accuracy, 5MHz class bandwidth and 22bit sampling
Each channel card type is available with one of three current input options in any combination in a single XT2640 ‐
D – Dual Shunt (up to 20Arms continuous and 150Apk inrush measurable, 250Apk withstand) in a single input terminal
pair with resolution down to 0.1µA – no need to change terminals
H ‐ High Current (up to 30Arms continuous and 200Apk inrush measurable, 300Apk withstand) with resolution down to
10µA
X – External Current Transducer or Shunt Input (up to 15Vrms) with resolution down to 0.1µV
Optional MT type motor channel provides analog or digital speed, direction and torque inputs for mechanical
measurements.
Up to three different Virtual Power Analyzers™ (VPAs) may be independently configured in the one unit for input/mid‐
point/output power and efficiency tests ‐ there is no need to interconnect separate units in order to make synchronous or non‐
synchronous group power measurements.
Measurements in each VPA are fully configured in a single screen at the touch of the screen, no hunting around for the
configuration setting you need. Each may be configured as Nx1ø (1 to 4ch), 2ø3w (2ch), 3ø3w (2ch), 3ø3w (3ch) or 3ø4w (3ch)
and each VPA has totally independent measurement configuration.
A choice of screens to view the measurements, just one touch to change between screens ‐
Power Data Screen ‐ displays V, A, W, VA, VAR and PF data for any single channel or for a group of channels, or displays
loading (impedance, resistance and capacitance/inductance), or displays mechanical speed, torque, power and motor slip
percentage, or displays power loss and efficiency.
Custom Power Data Screen ‐ lets you choose the data you want displayed in a color, font size and location you want, along
with any text you define
Harmonic Bar Chart Screen ‐ displays harmonics with flexibly scaled bar charts and also a scrollable textual listing of both
amplitude and phase results, and harmonics can be checked against user supplied limits for each harmonic with individual
harmonic and overall pass/fail indications
Spectrum Analysis Screen ‐ displays signal spectral content with a user cursor for obtaining numerical levels
