Next-generation load device "LCR load device" that realizes the efficiency of solo driving tests.
This is an LCR load device that can be used for tests specified in the "Individual Test Methods for System Interconnection Protection Devices."
This is a single-phase three-wire alternating current load device that supports various tests as LC loads and R loads. It is also possible to configure test equipment linked with other measuring instruments and power supplies through computer control. By using our developed products such as the grid connection test software (sold separately) and the power conditioner evaluation system (PVU01403), automatic grid connection testing for solar power system power conditioners can be conducted.

The R load device and LC load device catalog has been renewed.
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.
