The Yokogawa 253752-E1 Power Measurement Module delivers high-precision power analysis and monitoring for integration with Yokogawa data acquisition systems and the PZ4000 Power Analyzer. This module captures voltage and current waveforms across DC to 2 MHz with 5 MS/s maximum sampling rate, enabling detailed analysis of fluctuating power inputs. Harmonic content extends to the 500th order, while FFT processing supports high-frequency power spectrum analysis. Multi-channel synchronized measurement is possible when multiple units operate in master-slave configuration, maintaining synchronization to within 3 microseconds plus two sample points. Optional 4M-word internal memory accommodates extended low-frequency measurements and load transient capture.
