Description
- Simultaneous measurement of DC and AC signals
Evaluation of DC/AC signal conversion technology is critical in the renewable energy market. With input from 2 or more elements, the WT500 can measure DC and AC signals simultaneously and calculate input-to-output efficiency. - Separate integration functions for charge/discharge and bought/sold power
The WT500 is equipped with integration functions that can not only evaluate charge and discharge current such as from secondary cells, but also bought and sold power in photovoltaic power generation systems. - Saving measured data directly to USB memory
Measured data can be saved in CSV format directly to USB memory. - Easy setup with cursor keys
Menu-type screen offers intuitive setting. - Simultaneous measurement of normal data and harmonic data with the harmonic measurement, /G5 option
RMS voltage, RMS current, power values, and harmonic components up to the 50 order can be measured simultaneously. - WT series for power evaluation of energy-saving equipment
The WT series have been used as powermeters for Green IT, Energy Star, CO2 reduction and other energy-saving equipment. The WT series-Including the WT500--supports your power evaluation needs.
The WT500 Power Analyzer excels at single- and three-phase power measurements. Standard features include a color TFT display and USB interface for communications and memory. The instrument has a basic power accuracy of 0.1%, maximum inputs of 1000 V, 40 A and a measurement bandwidth of DC to 100 kHz.
Newly Designed Architecture
Intuitive control by using cursor keys in four different directions.
To reduce setting errors, menus display settings in order of relative importance in order.
Measured Value Direct Save Function
Two USB ports for peripherals are installed for direct data saving (up to 1 G byte) in USB memory at shortest intervals.
The saved data can be opened in applications such as Excel.
* Excel is a registered trademark of Microsoft Corporation in the U.S.A.
A Variety of Display Formats
In addition to numerical data, the WT500 can display input signal waveforms and trends (time variation of numerical data).
Bar graph display and vector display are also available with the harmonic measurement (/G5) option.
*1 Waveforms of up to approximately 5 kHz can be displayed.
*2 Excludes single-phase models.
Split screen display for numerical values and waveforms is not available.
Simple Setting and Display of Efficiency
|
Two efficiency calculations can be set by selecting input elements or output elements from a list. |
Example: η1 = PΣ/P1 x 100% η2 = PΣ/P2 x 100% |
USB Memory Storage Function
Only necessary items within the measured data like voltage, current, and power can be saved in USB memory in binary or CSV format (up to 1 GB).
Files saved in CSV format can be opened in general-purpose applications such as Excel to allow displaying of data in graphs.
Variety of Integration Functions
In addition to integration functions of active power (WP), current (q), reactive power (WQ), and apparent power (WS), a new feature provides measurement of bought and sold watt hours. Also, average active power can be calculated over an integration interval.
This feature is useful for evaluating the power consumed by intermittent-control instruments in which the power value fluctuates. Average active power is calculated by using user-defined settings.
GP-IB Communication (/C1)
GP-IB communication enables you to control the WT500 or transfer data from a PC.
Ethernet Communication (/C7)
Data can be transferred via Ethernet* communication.
It enables file transfers using an FTP server.
* 100BASE-TX
External Current Sensor Input (/EX1, /EX2, /EX3)
Current can be measured by using current clamps without disconnecting power supply wiring (voltage output type). By setting an external current sensor conversion ratio, it can support various types of current clamp-on probes.
VGA Output (/V1)
By connecting to a monitor, you can create large displays of numerical values and waveforms. This function is convenient for simultaneously confirming data on multiple monitors, or to check data remotely.
Harmonic Measurement (/G5)
This function enables simultaneous measurement of normal and harmonic data. Harmonic components of up to the 50th order can be measured. With the WT500 you can simultaneously confirm voltage, current, and the distortion factor (THD) as well as measure the distortion factor without switching modes.
Delta Computation (/DT)
This function allows you to calculate individual phase voltages and phase currents from the line voltages and phase currents measured in a three-phase, three-wire (3P3W) system. The phase voltage can be calculated from the line voltage measured with the three-phase, three-wire (3V3A) method. This is useful when you want to determine the phase voltage in a DUT with no neutral line by using the three-phase, three-wire (3V3A) method.
Note: This function cannot be installed on products with only one element.
Added Frequency Measurement (/FQ)
In addition to the standard two channels of frequency measurement, an option is available for frequency measurement on all channels. This option provides frequency measurement of voltage and current on all channels with input elements 1 through 3 installed.This is necessary when you want to measure voltage and current frequency from the instrument's I/O as well as voltage and current frequencies of multiple items under test at the same time.
Note: This function cannot be installed on products with only one input element.
