Typical Applications
The M100-WA series measures active power in single, 3 phase 3 or 4 wire balanced and unbalanced systems. Using the time division multiplier circuit means that they can be used over a wide range of input waveforms. The D.C. Output signal is directly proportional to the instantaneous power being measured. Typical applications include the measurement of power in switchboards, power stations, generating sets.
