GN310B

Input Card For High-Accuracy Power Measurements in Electric Drives and Electrical Grids – GN310B, GN311B

The power analyzer card offers three power channels, each one consisting of one voltage input and one current (or voltage) input. The card also offers 2 digital channels for torque and speed measurements.
It is specially designed for efficiency measurements in inverter-driven electric drive systems and all tests in grid-connected systems or the grid itself with 5 voltage ranges of up to ± 1500 V DC and 7 current ranges of up to ± 2 A.

The power analyzer card also offers the best-in-class power accuracy of 0.015% of reading + 0.02% of range.
