PR300 Power and Energy Meter

PR300 is a panel-mounted meter designed to meet two user needs: a power facility meter and a meter for monitoring energy consumption.

  • 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

Universal Design

PR300 versatilely 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.

【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.
