  • Large Triple Display and Multimeter Function
  • Wide Choice of Measurement Items
  • The Demand Alarm and Network Access Make Your Power Monitoring Even More Efficient.
  • Universal Design

Large Triple Display and Multimeter Function

Large Triple Display and Multimeter Function

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.

set/ent

PR300 comes with measurement functions for reactive power, apparent power, demand current, demand power, and other items, as well as with a transducer function.

SET/ENT 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. PLAY

【Support Information】List of RoHS

This is a list of recorder and controller products that support the RoHS (2011/65/EU) directive.

Overview:

The Japan Steel Works, LTD., Muroran Plant uses the Control and Measurement Station CX2000, UP series program controllers, and UT series digital indicating controllers for operation of its heat treating furnaces.

Industries:
Overview:

Okinawa Cellular Telephone Company has launched an experimental vegetable factory to encourage farmers in the prefecture to enter into that business. The 80 square meter vegetable factory engages in hydroponics, and uses 100% artificial lighting. Located at Nanjo City in the southern part of Okinawa island, the facility holds six levels of beds dedicated to raising greens like romaine and leaf lettuce.

Overview:

Improving manufacturing efficiency demands constant action - from uncovering operational waste to identifying areas for continuous improvement. Namely, we must always pursue a cycle of visualizing, analyzing, and solving energy saving challenges.

Overview:

Facing serious environmental problems for the whole earth, clean energy using solar, wind, geothermal, tidal, etc... to reduce CO2 emissions is an inevitable matter. Renewable energy providers need economical/reliable/efficient solutions. Yokogawa provides a reliable data acquisition system with high accuracy for measurement and control instruments.

Overview:

MW100 and PR300 system measures and quantifies the electrical energy consumption for each assembly line.

Overview:

Data from tests of multiple compressors run in parallel are saved to separate files for each compressor using the DAQWORX software suite.

Overview:

DAQWORX Data Acquisition Software Suite helps the administrative department collect and monitor data on each section of the factory, including data on the usage of chemicals, gas, and electricity.

Application Note
Overview:

Yokogawa Power Monitors measure energy in plants, such as power, current, voltage, power factor, etc. In addition, data acquisition for power, vapor, fuel, water, air, etc, and data monitoring using viewer software, are performed by connecting to the MW100 data acquisition unit.

Industries:
Overview:

A useful pre-shipment inspection for picking out defective items. Measures product watt hours, power, current, voltage, and other parameters before and after general inspection to check for abnormalities.

Overview:

It's easy to set up a monitoring system for power equipment that saves energy.

Overview:

Recent years have witnessed increasing corporate initiatives for energy savings and environmental protection due to laws and other ordinances, and this has affected power monitoring needs. As opposed to power monitoring on a large scale such as on the level of an entire factory, there are more and more examples of small scale power monitoring systems such as for manufacturing lines, or even for specific manufacturing equipment.

Overview:

MW100 Data Acquisition/Data Logging System with PR300 Power and Energy Meters

Overview:

In order to save energy and reduce rounds made for periodic inspections, you can set up acquisition and monitoring of power data and temperature data from converters, alarms warning against imminent shutoffs due to power overages, abnormal temperature alarms, and other mechanisms.

Industries:
Overview:

MW100 records solar power parameters such as radiance, ambient temperature and before/after electric conversion power data.

For voltage and current, select FLOAT32L (32 bit floating point). For integral power, it's UINT32L (unsigned 32 bit integer).
The unit on the display depends on the secondary rated power, VT ratio, and CT ratio. It is fixed, and cannot be changed. Ex. For active power, the measuring range and unit are determined as follows. Secondary rated power is the rated power in th...
Yes. Select one with a secondary current rating of 1 A or 5 A. The consumption VA of the PR300 itself is 0.2 VA, so check the rated load of the CT including the wiring.
Does the PR300 support the CCC standard?
(ns-faq-power-12022-spec)
The PR300 is not subject to CCC standards. It can be used in China.
You can do this as long as the measured line voltage is 100 to 240 VDC ±10%. Note that during maintenance on the PR300, if the power is OFF, you must also turn off the original power supply, so we recommend that you use a power supply on a dif...
Yes, but the measuring accuracy will be reduced by about 5 times, plus other limitations.
Select one to match the rated secondary current of the current transformer (CT) you are connecting.
Approximately 5 VDC.
We have a new version of the PR970 that supports Windows 7. You'll need to purchase that one.
What is a demand measurement function?
(ns-faq-power-12003-term)
The PR300's demand measurement function measures average power or current within a specified time limit. It also measures the maximum value during the period of demand measurement. When a specified demand alarm point is exceeded, an alarm is outp...
Yes. Any measurement element can be assigned to any of the three displays (upper, middle or lower). Specified phases of voltage and current can also be assigned, and you can scroll the displays through the phases with the SEL key.
We recommend the PR300 Power and Energy Meter.PR300 Product Information
