Yokogawa WT332E - Digital Power Analyzer 

2 input

The WT300E series is the enhanced version of Yokogawa’s 5th generation of compact power meters. The world’s best-selling power meter is the instrument of choice for a wide range of applications in production testing, quality assurance and Research & Development. 

 Accuracy with fast display and update rate

The WT300E series with the fast display update rate of 100ms, offer’s engineers a short tact time in their testing procedures. The basic accuracy for all input ranges is 0.1% rdg + 0.05% rng (50/60Hz) and DC 0.1% rdg + 0.2% rng.

 Auto ranging function available in selected ranges.

The auto-range function is used to select or change the ranges automatically, within specified ranges. This results in shorter range changing times, allowing more efficient testing.

Maximum direct input of up to 600V and 20A, or 40A (incase of WT310EH). The wide current input ranges on the WT310E series, give users the option to measure current as low as 50 micro-Amps to as high as 40Arms (incase of WT310EH).

 Bandwidth

DC and 0.1Hz to 100 kHz (WT310EH is up to 20 kHz for 40A)

  Simultaneous measurement of all parameters

The WT300E can measure all DC and AC parameters. can also measure harmonics and perform integration simultaneously without changing the measurement mode.

 Fast display and data update rate

The fast display and a maximum data update rate of 100ms on the WT300E series, offers a short tact time in testing procedures.

High-speed data update (up to 10 readings per second.)

 MAX hold function

The maximum values of RMS/PEAK Voltage & Current, Active Power, Reactive Power and Apparent Power can be held.

 Line filter and frequency filter capabilities

These filter functions will cut off unnecessary noise & harmonic components for fundamental waveform measurements.

 Free PC application software WTViewerFreePlus

The WTViewerFreePlus software can capture measured numeric values, harmonic values and waveform data. The data can be transferred to a PC via a USB, GP-IB/RS-232 or Ethernet communication interface, and it can be displayed* and saved on the PC.

*Waveform display requires /G5 Harmonic option

Application

Reference

 Production line or QA testing of electric devices

  • Compact half rack mount size helps engineers build smaller test systems with a better return on investment
  • D/A output and Modbus/TCP* functions for data recording
  • Multiple communication interfaces: USB, RS-232 or GP-IB and Ethernet capability

Testing_Electric_Device_with_Power_Meter_Yokogawa_WT310E.png

The simultaneous measurement of power consumption parameters such as U, I, P, frequency, power factor and harmonics for production line or QA testing results in reduced tact times. Thus testing is faster and low cost. The DA output and communication interfaces enable data to be remotely and flexibly captured. *“Modbus/TCP” function is supplied with the Ethernet (/C7 option).

 Evaluation of large current equipment

  • Direct high current measurements of up to 40Arms without using external sensors (WT310EH)
  • Auto ranging function for Integration mode.

The WT310EH allows 40 Arms to be directly connected to the input without the requirement to use current clamps or current sensors. This not only provides more precise measurement but also saves on investment costs.The wide current ranges are from 1 A to 40 A and voltage ranges are from 15 V to 600 V.

Users can use it to evaluate special waveform driven devices such as, IH cookers and heaters

 Duration testing and efficiency measurement for industrial motors and rotating machinery

  • Integration measurements over long periods of time
  • Modbus/TCP Protocol for data recording
  • DC, 0.1 Hz to 100 kHz broad bandwidth capability

The WT300E series provides reliable current integration (Ah) and Energy (Wh) measurements for up to 10,000 hours.

The D/A option can be used to transmit these measurements to an external data logger or recorder, such as a ScopeCorder, and monitor and log data along with other parameters, such as temperatures, torque, and rotation speed.

The Modbus/TCP communication with /C7 option is used to save and monitor the measurement results of up 200 chs.

YOKOGAWA GA10 data logging software can be used directly to save data along with other parameters such as temperatures, torque and rotation speed by this Modbus/TCP Protocol.

 Development and evaluation tool for home appliances

  • 5mA range allows for small current measurements (WT310E)
  • Auto ranging function during integration mode
  • Range skip (range configuration) function provides the ability to select usable ranges in advance. Auto ranging enables the WT300E series to rapidly adapt to changing input conditions

 Automotive- Battery or DC driven device evaluation

  • Accurate DC measurements: 0.3% total
  • Direct high current measurement of up to 40A without any external current sensor.
  • Charge/Discharge energy measurements for batteries

 Conformance and evaluation testing of uninterruptable power supplies (UPS)

  • Maximum harmonic order settings for THD calculations
  • Efficiency measurements using a single power meter
  • Average Active Power measurement under integration mode

The WT300E series enables users to conduct conformity tests according to UPS performance testing standards.

The WT300E series is used to measure and calculate input & output levels, efficiency, frequency and THD. The average active power data also provides accurate values of power consumption. This equipment along with the WTViewerFreePlus software helps to simultaneously measure all necessary parameters required to test a UPS, thereby reducing the evaluation time.

.

Comparator Function

The WT300E series outputs +5 V, 0 V, or −5 V. To replace the output with a relay contact output, like the WT210/WT230 comparator function, a user can implement their own relay and driving circuit.

.

Automatic zero adjustment

The WT300E series compensates for any drift in the zero level by automatically performing a zero adjustment when the input ranges are changed. This is achieved in less than 100 ms and does not require disconnecting wires.
