Specifications
Up to the 500th order harmonic can be measured at
a 400 Hz fundamental frequency. Also, up to the
255th order harmonic can be measured at 1 kHz. Up
to 150 kHz harmonic measurements are supported
for aircraft testing that requires high order harmonic
measurements.
WTViewer is application software that allows you to read
numerical data measured with a WT1800 Precision Power
Analyzer to a PC via Ethernet, GP-IB, or USB communication,
and display and save the numerical values.
Up to 12 power inputs can be measured simultaneously in
synchronized measurements between two units. Also, the
ability to collect data of up to four WT1800 units allows you
to measure the conversion efficiency, power, and power loss
of up to 24 power inputs.
n Integrated Power and Harmonic Distortion Factor
Measurements
The WT1800 is capable of measuring long hours of integrated current (Ah) and power (Wh) in
order to understand the amount of power consumption. It is not only possible to measure
50/60 Hz AC signals, but also perform high precision DC measurement indispensable for the
DC power supply evaluation. Also, the /AUX option input allows you to monitor heat
generation, etc.
In addition, a DA output function (/DA option) allows you to output analog signals to an
external recorder (ScopeCorder, etc.) and perform long hours of monitoring of current and
power along with the temperature and other data.

Overview
New large data centers based on cloud computing are being constructed while
the importance of energy conservation is growing. Since the WT1800 is
capable of measuring up to 6 power inputs, the current and power
consumption of up to six servers can be measured with a single unit. The
standard GP-IB, USB, and Ethernet communication functions allow the operator
to monitor data in multiple locations by collecting data via communication.
Overview
High order harmonic measurements are important in the aircraft industry.
The WT1800 provides a function to measure up to 150 kHz harmonics and
allows you to measure up to the 500th order harmonic.
Advantages of WT1800 Advantages of WT1800
*An external input terminal (EX) allows you to measure both direct input measurement and clamp measurement.
*Direct input and current sensor input cannot be connected simultaneously.
*For detailed specifications, see the page on the specifications. You need to provide a cable for voltage measurements when wiring.
