VigilantPlant excels at bringing out the best in your plant and your
people - keeping them fully aware, well informed, and ready to face the
next challenge. The Yokogawa PR300 Power-and-energy POWERCERT Meter is a
core building block of Yokogawa's VigilantPlant solutions that promise
to bring operational excellence to visionary plants. |
Large Triple Display and Multimeter
Combine three desired measurement items and show them all at once on the
large LED display. Just one PR300 unit can take the place of two or more
meters, dramatically contributing to savings in cost, space and wiring.
The PR300 comes with measurement functions for reactive power, apparent
power, demand current, demand power, and other items, as well as with a
transducer function. The user can optionally select an item to be
displayed for each line of the display. Even during measurement, the
display parameter can be changed with one touch using the SET/ENT key.

Demand Alarm and Network Access
The PR300 comes complete with functions necessary for efficient
power monitoring, including power integration over a desired period,
a transducer function (4 - 20 mA DC output), an integrated pulse
output of electric energy, demand current/power alarm output
functions, RS-485 communication (Modbus/PC link), and Ethernet
communication.
Universal Design
PR300 versatility supports a wide range of phases and wire systems,
from a single-phase two-wire system to a three-phase four-wire
system. The phase and/or wire system, including CT/VT ratios, can be
selected or changed on site using the panel keys. For panel
mounting, PR300 supports various standards with different shapes and
sizes. |
