Maximize Efficiency of Power DevicesWhy is Evaluating Conversion Efficiency Important?

Helping Customers Bring the Best Products to Market

What Do You Get?

New energy sources such photovoltaic, wind and fuel cell systems are becoming increasingly popular. The power generated by these new energy sources is often connected to grids, or the traditional power supply network, after converting to 50 or 60Hz signals using a power conditioner, which uses a power inverter with a sine wave output. To ensure that the precious energy sources are maximized to their fullest potential, it is important to evaluate the conversion efficiency and output of the power conditioners. Even a 1% increase in efficiency can lead to tremendous overall savings.

High-accuracy, multi-channel power meters save manufacturers time and money by enabling the simultaneous testing of both primary and secondary AC and DC signals. The PW3337 outperforms competitors by providing independently configurable range settings for each side, enabling you to use the optimal range and assuring the proper resolution and precision to make a valid analysis.

Steps to Analyzing Power Conditioner Efficiency

✔ Measure the output at the primary DC side and secondary 3-phase AC side, setting the optimal range for eachHow? Because the PW3337 has 3 independently configurable AC and DC channels

✔ Monitor and record the resulting efficiency displayed on the PW3337How? Because the PW3337 comes with 4 rows of displays and the data can be downloaded to a PC

✔ Use clamp sensors if the measured current exceeds 65AHow? Because the PW3337 has built-in current sensor input terminals to support the larger currents

✔ Calculate efficiency by performing output/input calculations ✔ Calculate the ripple rate: what is the ratio of the AC component that is superimposed on the DC line? ✔ Test for harmonic components such as voltage THD, which can be a concern with grid-linked systems

How? Because the PW3337 has advanced built-in processing of all power and harmonic data!

By connecting one of a variety of Hioki clamp on sensors to the PW3337, you can measure currents of up to 5,000 A AC with guaranteed accuracy. Choose from a range of high-accuracy, clamps or pass-through AC/DC current sensors and models specifically designed for 50/60 Hz measurement. Clamp sensor terminals are built-in to the power meter at no additional charge.

Issues with Inverters What Do You Get?

Motor control using inverters is increasingly on the rise as a means to save energy and drive efficiency. In daily life, inverters are widely used in electrical appliances such as air-conditioners and refrigerators, and as well as the motors used in elevators and pumps, etc. In addition, inverters are used for UPS (uninterruptible power supply), fluorescent lamps, LCD backlights, and other common devices. Recently, applications for inverters are further spreading to motor control of electric vehicles and hybrid cars, as well as power conditioners for new energy sources like photovoltaic systems. As demand for energy saving measures increase in the near future, so will the applications incorporating inverter technology.

Inverters are becoming indispensable, but they are also notorious as a source of harmonics and noise. Inverter output also contains a high level of common mode voltage, so it is critical that the output is measured in order to evaluate the inverter’s abilities as well as the subsequent motor control through the use of the inverter. A high accuracy multi-functional power meter is indispensable in verifying the inverter's true capabilities and helps developers make corrections to the inverter's design so that the power source is optimized.

Steps to Analyzing Inverter Efficiency

✔ Connect multiple instruments to synchronize their operation, including display updates, data updates, and start of integrationHow? Because you can synchronize up to 8 units of Model PW3337

✔ Measure all data with simultaneous parallel processing, including RMS values, mean values, fundamental wave components, THD, and harmonic componentsHow? Because the PW3337 has advanced built-in processing of all power and harmonic data!

✔ Measure the wide frequency band at the inverter's secondary sideHow? Because the PW3337 offers an expanded frequency band from DC and 0.1 Hz to 100 kHz

✔ Use clamp sensors if the measured current exceeds 65AHow? Because the PW3337 has built-in current sensor input terminals to support the larger currents
