- Wide Choice of Measurement Items
- The Demand Alarm and Network Access Make Your Power Monitoring Even More Efficient.
- Universal Design
Details
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.
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. 
Examples of Display Item Combinatons
* Use SEL key to view phase Amps and Volts.
Wide Choice of Measurement Items
*denotes optional.
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.
Universal Design
These make your power monitoring even more efficient!
Other RS-485 devices can be connected to the network using Ethernet–serial gateway function.
PR300 comes complete with functions necessary for efficient power monitoring, including power integration over a desired period, a transducer function (4 to 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.
Integrated power monitoring by Daqstation
Data acquisition and monitoring using the recorder
The Ethernet-serial gateway function enables connection between the PR300 and RS-485 devices.
Browser-assisted monitoring by DAQMASTER
Data logging by MW100
Monitoring is assisted by the browser, and data are transferred by the FTP function.
Network instrumentation by DAQWORX
Capable of measuring energy and environmental factors
Connection with control devices is possible via the network (10BASE-T/100BASE-TX). Data logging is performed by PC.

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.
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.
