Multifunction Meter measures power and energy.
July 11, 2006 -
Featuring 3 separate LED displays, compact PR300 measures Amps and Volts per phase, Watts, VAR's, VA, Hz and Power Factor with instantaneous/min/max readings. Meter suits worldwide use with universal mounting options (DIN or ANSI), wiring from 1p2w-3p4w systems, and AC/DC power supply. Voltage inputs are menu-selectable from 150-600 Vac. RS485 serial communications with MODBUS® RTU/ASCII protocol is standard, with optional Ethernet 10BASE-T/100BASE-TX available.

Yokogawa Adds PR300 to POWERCERT® Power and Energy Meter Lineup
Newnan, Georgia - Yokogawa Corporation of America introduces the PR300, a new addition to the POWERCERT® family of panel-mounted power and energy meters. It was developed for worldwide use with universal mounting options (DIN or ANSI), universal wiring from 1p2w to 3p4w systems, and a universal AC/DC power supply. Voltage inputs are menu-selectable from 150VAC up to 600VAC. CT/PT ratios can be set from the front panel or with communications.
The PR300 compact multifunction meter, with three separate LED displays, will measure Amps and Volts per phase, Watts, VAR's, VA, Hz and Power Factor (all with instantaneous/min/max readings). Other measurement functions include active energy (kWh, MWh), reactive energy (kVArh, MVArh) and Apparent energy (kVAh, MVAh). In addition, RS485 serial communications with MODBUS® RTU/ASCII protocol is a standard feature; and Ethernet 10BASE-T/100BASE-TX is available as an option. Other options include demand current/power measurement with alarm output, selectable analog output, pulse output and digital input for remote integration or alarm reset.
Development Background
Until recently, the POWERCERT® series of power monitors were available mainly in Japan where the need to reduce energy consumption was particularly pressing. Following the Kyoto Protocol in February 2005, the implementation of practical measures to reduce energy consumption and cut back on greenhouse gas emissions has been on the increase all over the world. As a result, the demand for power monitors used in energy saving applications is rising worldwide; and the PR300 fulfills a host of power monitoring functions for that purpose.
Major Markets
o Manufacturers of electrical power equipment such as switchgear and generator
controls.
o Power utility suppliers and Industrial end-user production sites and
buildings.
o Automation and energy management systems for
commercial/institutional/governmental facilities.
