The LS3300 from Yokogawa is an AC signal generator capable of outputting both current and voltage simultaneously, thus allowing it to calibrate power measurement instruments such as current clamps/transformers, panel meters, RMS multimeters, and power meters. Also shown, a short programming example as well as the signal shown on the Yokogawa DL95

Are you a developer focused on battery systems or automotive?
If you’re looking to integrate precise DC current and voltage measurements into your project, consider our compact solution that supports both EtherCAT and CAN communication protocols.

Our device offers a small footprint, making it ideal for applications where space is at a premium. With EtherCAT, you can ensure high-speed, real-time data transmission, critical for monitoring and controlling fast dynamic processes. CAN support provides the robustness and reliability.

How to easily get accurate power measurements from WT5000 via modbus into the Yokogawa loggers.

By employing the advanced filter capabilities of the Yokogawa WT5000, one can effectively separate and analyze both the switching frequency and the fundamental frequency within a PWM motor voltage signal. to get detailed understanding of the motor’s electrical characteristics and the behavior of the PWM drive system. FFT analysis can also be performed
