78M6631 Data Sheet

1.5 Digital Computation Engine (CE)

The CE, a dedicated 32-bit digital signal processor, performs the back-end computations. CE calculations

include:

• 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.
