WM14 DIN and WM14 96 available as Basic and Advanced
power analyzers can be used in all the applications where it
is needed to measure and control the main electrical
parameters and to transmit them by pulses, by serial
communication or Profibus DP to a PLC or a PC. WM14 is
compact and is available either for panel mounting or DIN-
rail mounting.
WM14 is the natural evolution of WM12. It maintains the
same advantages and measurement capabilities of the
multi function meter providing the following additional
features and benefits:
• Metering of both total and partial active and reactive
energies with pulse outputs in order to survey not only
the typical load parameters but also the consumptions.
• Measurement of the thermal current, by single phase,
and recording of the maximum demands. This
information will let the maintenance people know if the
over current protections (fuses, automatic switches,
etc.) are adequately preset and in case of trip which is
their real current.
• Hour counter meter function. On board of a machine or
a generating-set, the instrument shows how long those
machines are being used saving also the cost of an
external classical hour counter meter. A proper
“machine usage” cost and/or mechanical maintenance
can be estimated and planned.
• OR/AND control of up to 16 selected variables so to grant
an extended load or line control through 2 digital outputs.
