OMEGAs OM10 Series watt
transducers accept AC voltages
and currents to produce a
conditioned dc process signal
output representing wattage. Single,
dual, and three element models are
available to accommodate a variety
of wiring configurations. For larger
input voltages and currents, the
OM10 may also be used with
OMEGAs voltage and current
transformers.
