Active Power Transducers

Posted on Posted in Transducers

Description

DIN rail mounting transducers available in 55mm x 112mm or 100 x 112mm DIN  rail cases

Application

Used to convert various inputs into standard DC signals for driving panel meters and for use in control devices.

Selection Guide

M100-WA1 Single Phase
M100-WA2 3 phase 3 wire balanced load
M100-WA3 3 phase 4 wire balanced load
M100-WA4 3 phase 3 wire unbalanced
M100-WA5 3 phase 4 wire unbalanced load
M100-WA6 3 phase 3 wire balanced load externally connected
reverse CT’S
 

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.
