Benchtop power analysis for alternative energy

Tag : usb power supply

Its three input channels can be set independently to measuredifferent parameters and ranges, making it ideally suited to AC orDC measurements of input/output conversion efficiency.
Optional harmonic measurement functions can be used to measure theharmonic components of the voltage, current and power as well asthe normal (total) measurement values.
In addition, the RMS voltage and current (the total of the RMSvalues of all the frequency components in the measurement frequencybandwidth) can be measured simultaneously with the harmonicmeasurements.
The WT500 is designed for ease of use, with a set-up key accessinga range of pull-down menus.
The ease and speed with which functions and set-up parameters canbe accessed is a major advantage in efficiency measurements in aproduction-line environment.
Easily accessed functions include range selection, scaling,synchronisation source, line and frequency filters, update rate,averaging, and integration.
The WT500 can integrate the active power (watt-hour), the current(ampere-hour), the apparent power (volt-ampere-hour) and thereactive power (VAR-hour).
During integration, the measured and computed values of normalmeasurements can be displayed in addition to the watt-hour,current-hour, volt-ampere-hour, VAR-hour, sold/bought power andintegration time.
Other features include user-defined functions, frequencymeasurement, harmonics setting and delta computation.
In addition, a 'miscellaneous' key displays a menu for systemoverview, setting the date/time, selecting the message language,selecting the menu language, setting the display colour and settingthe self-test function.
A remote-control function is also available via the standard USBand optional GP-IB and Ethernet interfaces, while a store functionis used to save directly to an external USB memory.
