Solar cell strings with a system voltage of up to 400V can be measured. Reliable I-V measurement with a linear sweep within 200[ms]. [Demo units available for loan.]
The "Epsilon 400" is an IV curve tracer that supports the voltage range of 400V, which is common for many residential solar power generation systems. It has been newly renewed from the old model PVA12280! Compact and lightweight, it features simple operability and beautiful displays on a color LCD. It can store up to 9999 data points in internal memory, and it allows for approximately 1-second result display, enabling short-term measurements that are less affected by sudden changes in sunlight or shadows. 【Features】 ■ Capable of measuring 400[V] and 30[A] ■ Equipped with an automatic measurement function (manual/automatic selection available) ■ Japanese mode added to the operation guide (English also selectable) ■ Safe operation with reverse connection detection function (misuse detection) ■ Internal data storage capacity of 9999 points, suitable for large-scale power plants ■ Reliable and smooth graph display through 1024-point measurements ■ Linear sweep within 200[ms], with results displayed in about 1 second * For more details, please refer to the PDF document or feel free to contact us. * Demo units are also available for loan, so please get in touch.

Company information
Since the time of the Sunshine Project at the current Ministry of Economy, Trade and Industry, we have developed simulated power sources, measuring instruments, power conditioners, and more, in response to requests from organizations such as the National Institute of Advanced Industrial Science and Technology, the Central Research Institute of Electric Power Industry, and Tokyo University of Agriculture and Technology. Based on these achievements, we have commercialized our products and expanded sales to various research institutes and manufacturers, proudly positioning ourselves as a niche leader in this field. We specialize in the development of products and systems that combine hardware and software, including simulated power sources such as solar cells and storage batteries, load devices necessary for grid connection testing, and testing systems that operate these components collectively. We also have extensive experience in solar cell measurement, and our I-V curve tracer is widely used not only for the maintenance of solar power plants but also for research and development purposes at manufacturers, research institutions, and universities. We have numerous delivery records of automated measurement systems that incorporate measuring instruments and load devices. Development of power electronics equipment that combines analog and digital technologies, development of control software using DSP, and construction of PV measurement systems are among the services we offer, tailored to meet our customers' needs.
