Proper Accuracy and Bandwidth to Precisely
Measure Inverter Output
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 Wide variety of built-in interfaces, including LAN, USB (communication, memory), CF cards, RS-232C, synchronization control, and external control. * Built-in for PW3390-02 and PW3390-03 | |
Switch Screens with a Single Touch, Accessing a Variety of Power Analysis Methods The power analysis engine allows the simultaneous, parallel calculation of all parameters. Access a variety of analysis methods simply by pressing the page keys to switch screens. |
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. |
Measure the Efficiency of PV Power Conditioners (PCS)
HIOKI's Current Measurement Solutions for Large Currents of 1000 A or More Introducing a lineup of sensors taking measurements up to 6000 A for 50 Hz/60 Hz, and up to 2000 A for direct current.
