PR300Power and Energy Meter

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

Various meters are integratedinto one instrument.

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 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.

Other RS-485 devices can be connected to the network using Ethernet–serial gateway function.

• Examples of Display Item Combinations

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

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.

The demand alarm and network access make your power monitoring even more efficient.

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.
