The CE, a dedicated 32-bit digital signal processor, performs the back-end computations. CE calculations
include:
•
Rev 1
Gain and offset compensation
Delay compensation on all channels
90° phase shift for VAR calculations
Frequency measurement
Accumulation for voltage and current RMS and power computation
Active, reactive, apparent, fundamental, and harmonic power calculation
Fundamental and harmonic current and voltage calculations
Monitoring of the input signal frequency (for frequency and phase information)
Monitoring of the input signal amplitude (for sag detection)
Temperature acquisition
Due to the custom nature and complexity of the CE, the CE code is part of the installed firmware and
is not modified by the user. Contact Maxim support for more information regarding CE code.
