Chi tiết Sản phẩm
Digital Power Meter
P/N: WT310E-C2-F ( interface RS232C)
The WT300E series digital power analyzer provides extremely low current measurement capability down to 50 micro-Amps, and a maximum of up to 26 Amps RMS.
This instrument is ideal for engineers performing stand-by power measurements, Energy Star®, SPECpower and IEC62301 / EN50564 testing,
battery charger and other low-level power measurements.

The WT300E's wide range of functions and enhanced specifications, allows handling of all the measurement applications from low frequency to high frequency inverters using a single power meter.
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.
U/I/P/Freq/Integ(+/-)/Harmonics components/ THD with max. 100ms cycle.
In addition to standard power measurements, the WT300E series measures all DC and AC parameters.
Additionally, the WT300E series can measure harmonics and perform integration simultaneously without changing the measurement mode.
The accompanying WTViewerFreePlus software can monitor and save the 200 parameters used.
Auto Ranging Function For Integration Measurement
Typically, when power meters operate in an integration mode to measure power consumption and standby power, the measuring ranges need to be fixed.
However, if the level of the input exceeds the maximum of the selected range, the test will need to be repeated.
The WT300E Series has a high-speed automatic ranging capability in integration mode, which removes the need to repeat any test.
Bandwidth: DC and 0.1Hz to 100 kHz (WT310EH is up to 20 kHz for 40A).
Direct Input: 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).
High-speed data update (up to 10 readings per second.

THe WT300E series offers a wide range of communication interfaces such as USB, GP-IB or RS-232 (selectable) and Ethernet Modbus/TCP (Optional)
Wide current input range
Wide current input ranges: The WT300E series covers a broad range of current inputs, from few mA up to 40 A rms. Both AC and DC waveforms can be measured.
Simultaneous measurement of all parameters: The WT300E can measure all DC and AC parameters. The WT300E series 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.
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.
Users therefore have the flexibility to choose a variety of settings according to their application needs e.g. from production lines to engineering test benches. Users can use WTViewerFreePlus software to set up all basic and advanced measurements. Additionally, the numeric values, waveform display* and trend graphs of the measurement data can be displayed and saved.
*Waveform display requires the /G5 Harmonic option
Connectivity of Modbus/TCP*1 with YOKOGAWA’s recorders and Ethernet*1 with PLC
Digital data measured by the WT series can be acquired by YOKOGAWA’s recorder GP10*2, *3 and GM*2, *3 via Ethernet or Modbus/TCP directly. It is also possible to make use of the GA10*2 data logging software to monitor and record data.
The WT300E series can also be connected with YOKOGAWA’s PLC, FA-M3V*2 using Modbus TCP protocol for production fields.
*1 /C7 Ethernet option is required.
*2 GP10/GM/GA10/FA-M3V are manufactured by Yokogawa Electric Corporation.
*3 /E2 and /MC options are required.
D/A output for measurement recording
The D/A option is used to output Voltage, Current, Power, and other measured data for recording to data loggers using the +/-5Vdc scaled outputs.
This mode will compare measured, computed, and integrated values with previously set determined values by the communication command, and output (from -5V to +5V) determined results by D/A output.
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.
