Datasheet
Figure 2. U1272A helps you identify the presence of stray voltage on a disconnected wire running parallel with the wire powering up the
VFD to an industrial motor. The image on the right shows the U1272A in low impedance mode.
Low impedance mode
Stray voltages are usually found in
non-energized electrical wiring adjacent
to powered wires due to capacitive or
inductive coupling between these wires.
The low impedance mode serves to
eliminate false readings by dissipating
these stray voltages thus improves safety
and measurement efficiency during
voltage measurement.
Peak detect at 250 µs
The peak detect function allows you
to capture the engine or motor startup
transient as fast as 250 µs.
