WT210/WT230 DIGITAL POWER METERS
The WT210/WT230 has five times the high-frequency range and approximately twice the basic accuracy as the previous generations plus a high-speed data acquisition rate and a compact design make this digital power meter highly desirable.
The WT230's advanced specifications and its wide range of functions let you handle all your measurement applications from low-frequency equipment to high frequency inverters using a single power meter.
A high frequency range and improved precision make this power meter an excellent tool.
· Maximum input with assured accuracy: 26 A
· Basic accuracy: 0.1%
· DC measurement: 0.5 Hz to 100 kHz frequency range
· Compact design (half-rack size)
· 5 mA range for very low current measurements (model WT210 only)
· Line filter function
· High-speed data update (as fast as 10 readings per second)
· Harmonic measurement function available
· User calibration capability
· Large-current measurement capability using external sensor input
· Basic Characteristics
· Comparison with Former Models
· Easily Acquire and Manage Power Measurement Data from Your PC
Wide Frequency Range
Wide Frequency Range Lets You Work on a Variety of Different Applications
· Low-frequency EquipmentLow-frequency measurements starting at 0.5 Hz can be used for evaluations of cycloconverters and when a motor are started.
· Commercial Power SuppliesBasic Power Accuracy: 0.1%
Power accuracy is even better than in fomer WT200/WT130 series.
· Inverters100 kHz power frequency rangeNow you can obtain more precise measurements on high-frequency equipment such as inverters.
