We have renewed the product features and applications to make them easier to understand, so please take a look. ーーーーーーーーーー This is a next-generation load device composed solely of passive components (resistors, reactors, capacitors) that allows for the setting of active/reactive power (leading/lagging). By connecting a computer software to a power meter, constant power control is possible even when the voltage changes. In evaluating power supplies and measuring instruments (such as power conditioners, UPS, power factor transducers, etc.), tests can be conducted without worrying about control resonance or load responsiveness that may occur when using electronic loads. Additionally, when evaluating power conditioners, using our grid connection testing software in conjunction allows for automatic execution of everything from load adjustment for anti-islanding tests to test implementation and report generation, significantly reducing the man-hours required for testing.

Our (Chuo Ward, Osaka) grid connection testing environment has been renewed! ● Testing capacity has increased! 6 [kW] → 8 [kW] ● Smooth automatic testing is possible using the "Grid Connection Automatic Testing Software." https://www.kernel-sys.co.jp/product/autoTest/ ● A new product, "Testing Script Creation Software," is also available. https://www.kernel-sys.co.jp/product/autoTest/testscript_index.html You can also utilize partial tests, such as "remote output control function testing only" or "standalone operation testing only," on an hourly basis. ▼ For more details ▼ https://www.kernel-sys.co.jp/support/p_pdf/AutomaticTest.pdf Our staff will be present to support the testing. Consultation on test content, contracting for tests, and site visits are also possible, so please feel free to contact us!
