Typical Applications
The M100-WA series measure active power in single, three phase three or four 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 etc.
The high isolation of 4kV as with all the M100 series, allow these watt transducers to be connected to a variety of measuring and control devices and systems, such as analogue meters, PLC, computers, data loggers, digital instruments and telemetry systems.
Both auxiliary powered and self powered versions of each type are available, it is recommended to use an auxiliary powered version if the system being measured has voltage variations in excess of ± 20%.
