Test Automobile Fuel Economy



Evaluate WLTP Mode Performance - A New Fuel Economy Standard

Taking fuel economy measurements that comply with WLTP standards requires the precise measurement of current integration and power integration for the recharging/discharging of each battery in the system. High accuracy clamp current sensors, the excellent DC accuracy of the PW3390, and the ability to integrate current and power at 50 ms intervals are extremely effective in meeting this application.


Optimal Current Sensors for Automotive Testing

Easily connect high accuracy clamp-type sensors without cutting the cables. Sensors operate over a temperature range of -40°C to 85°C (-40°F to 185°F), characteristics that enable highly accurate measurements even inside the engine room of a car.


Current and Power Integration Function by Polarity

DC integration measurement integrates the recharging power and discharging power by polarity for every sample at 500 kS/s, and measures positive-direction power magnitude, negative-direction power magnitude, and the sum of positive- and negative-direction power magnitude during the integration period. Accurate measurement of recharging power and discharging power is possible even if there is rapid repetition of battery recharging/discharging.


Link to Peripheral Devices via External Control

Use external control terminals to START/STOP integration and capture screen shots. This makes it easy to control operations from console switches and link to the timing of other instruments when measuring the performance of an actual automobile.


Proper Accuracy and Bandwidth to Precisely Measure Inverter Output


Complete Pursuit of Measurement Accuracy and High Frequency Characteristics

The PW3390 delivers 4 input channels and ±0.04% basic accuracy for power - the top instrument in its class. Achieve more precise measurements of the power and efficiency of high efficiency equipment used in power electronics. Further, a 200 kHz measurement band and flat amplitude and phase characteristics up to high frequencies enable the precise measurement of power at top frequency levels and low power factor.


Power Analysis Engine That Achieves High-Speed Simultaneous Calculation on 5 Systems

Precisely capture input waveforms with 500 kS/s high-speed sampling and a high resolution 16-bit A/D converter. The power analysis engine performs independent digital processing for 5 systems: period detection, wideband power analysis, harmonic analysis, waveform analysis, and noise analysis. High-speed simultaneous calculation processing enables both precise measurements and a 50 ms data refresh rate.


Current Sensors for the Thorough Pursuit of High Accuracy

-High Accuracy Sensor Pass-Through Type Pass-through type with high accuracy and a wide measurement range. Conduct extremely accurate measurements of large currents to a maximum of 1000 A over a wide operating temperature range. -High Accuracy Sensor Clamp Type Clamp for quick and easy connections. Conduct extremely accurate measurements of large currents to a maximum of 1000 A over a wide operating temperature range. -High Accuracy Sensor Direct Wire Type Newly developed DCCT method delivers expansive measurement range and superior measurement accuracy at a rating of 50 A.


Built-in Current Sensor Phase Shift Function
Achieve Superior Accuracy for High-Frequency, Low Power Factor Power

Equipped with new virtual oversampling technology. Achieve phase shift equivalent to 200 MS/s while maintaining a high speed of 500 kS/s, as well as a high resolution of 16 bits. Set and correct the phase error of the current sensor at a resolution of 0.01°. Use of the phase shift function results in a dramatic reduction of measurement error. This allows the measurement of high-frequency, low-power factor power included in the switching frequency of inverter output, which is difficult to measure with conventional equipment. * Virtual oversampling: Technology that uses a sampling frequency several hundred times higher than the actual sampling frequency to perform virtual deskewing.


In the Laboratory or in the Field


Take Highly Accurate Measurements Even in Tough Temperature Conditions

Severe temperature environments, such as engine rooms with intense temperature changes and constant temperature rooms, can hinder high accuracy measurements. The extremely accurate pass-through and clamp type sensors both feature excellent temperature characteristics and a wide operation temperature range to help address these challenges.


Achieve High Accuracy Measurement Even in the Field

Dramatically compact and light-weight form factor achieved by concentrating the calculation functions in the power analysis engine. Highly accurate measurements normally achieved in the laboratory are now also possible in the field.


Max. 6000 A Measurement on 50 Hz/60 Hz Lines

The CT7040 AC FLEXIBLE CURRENT SENSOR series can measure commercial power lines up to 6000 A, including solar power conditioner output. Even thick cables can be wired easily among crowded wiring or in narrow locations.


External Power Supply Not Needed for Sensor Connections

Power can be supplied to the current sensor from the main unit, so there is no need to provide a separate external power supply for the current sensor. Connected sensors are recognized automatically, for reliable and quick measurements.


Wiring Displays and Quick Setup Lets You Begin Measuring Immediately

Perform wiring while checking wiring diagrams and vectors on the screen. Optimum settings are performed automatically simply by selecting a connection and using the quick setup function.


New Method for Measuring Large Current over Multi-Cable Wiring

Highly accurate measurement of current in multi-cable wiring with large currents has been difficult-until now. The CT9557 adds the output waveforms from the high accuracy sensors connected to each branch line of the multi-cable wiring, for the highly accurate measurement of large currents.


Extensive Interface for Linking with External Devices

Measure the Power Conversion Efficiency of Inverters



Highly Accurate and Fast 50 ms Calculation of Power in Transient State

Measure power transient states, including motor operations such as starting and accelerating, at 50ms refresh rates. Automatically measure and keep up with power with fluctuating frequencies, from a minimum of 0.5Hz.


Combined Accuracy of Current Sensors Applicable throughout Entire Range

Combined accuracy throughout the entire range is provided through the use of a built-to-order high accuracy pass-through type current sensor. Obtain highly accurate measurements regardless of range, from large to minute currents, even for loads that fluctuate greatly. * High-accuracy specifications are not defined for the built-to-order high accuracy current sensor when used alone.


Measure High-Frequency Noise in Inverters

Power supply problems caused by high switching inverter frequencies are unrelated to the fundamental frequency, making it difficult to conduct proper harmonic analysis. The noise analysis function performs a frequency analysis of noise components up to 100 kHz, and displays the frequency, and voltage and current levels for the top 10 points. This is effective for measuring high-frequency noise in inverters.


Acquire Data from up to 8 Synchronized Units (32 Channels)

When you connect CONNECTION CABLE 9683 to multiple PW3390 units, the control signals and internal clocks synchronize. From the master unit, you can control the measurement timing on the PW3390 units that are set as slaves. With interval measurement, you can save synchronized measurement data to a CF card or a PC to achieve simultaneous measurements across a larger number of systems.


Analyze and Measure EV/HEV Inverter Motors



Electric Angle Measurement of Motors (PW3390-03 only)

The PW3390-03 features a built-in electric angle measurement function required for vector control via dq coordinate systems in high-efficiency synchronized motors. Make real-time measurements of phase angles for voltage and current fundamental wave components based on encoder pulses. Further, zero-adjustment of the phase angle when induced voltage occurs allows electric angle measurement based on the inductive voltage phase. Electric angle can also be used as an Ld and Lq calculation parameter for synchronized motors.


Measure Harmonics with Consideration for PWM Waveform Characteristics

The zero-crossing filter automatically matches the input frequency in the range of 0.5 Hz to 5 kHz to reliably detect the fundamental frequency. Further, harmonic analysis that is based on the fundamental frequency automatically prevents aliasing error using a digital AAF, which allows both precision and measurement reproducibility at a high level.


Transfer to Data Logger via Bluetooth® wireless technology

Connect the PW3390 and a data logger (with support of LR8410 Link) via Bluetooth® wireless technology to wirelessly transmit 8 parameters of measurement values from the PW3390 to the data logger. In addition to the voltage, temperature, humidity, and other parameters measured by the multichannel data logger, you can also integrate the measurement values of the PW3390 and observe and record them in real time.
